Hot strip mill production planning and sequencing
by Mohammad Reza Yadollahpour, Behrooz ArbabShirani
Abstract: Production planning and sequencing in Hot Strip Mill (HSM) process consists of decision making about three important issues: assigning the orders to slabs, building up programs from the slabs, and sequencing the programs on rolling machines. In contrast to earlier investigations that mostly focus on one of these issues, a comprehensive mathematical model where considerations for both mid and short term planning horizons are simultaneously taken into account is presented to formulate the whole problem. A greedy algorithm is then presented to solve the model in a reasonable amount of time and used for planning in Mobarakeh Steel Company (MSC), the biggest steel enterprise in the Middle East. Computational experiments demonstrate that the proposed method substantially increases the productivity in MSC by decreasing the total tardiness of orders, unsupplied demands of products, setup times and optimally utilizing the lifespans of rollers.

Performance evaluation of TQM attainment in Indian manufacturing sector
by Vineet Gupta, Dixit Garg, Raj Kumar
Abstract: Total Quality Management (TQM) improves product quality, expands business goodwill, provides competitive edge and increases customer base with satisfaction. Most enterprises agree with TQM potential and they have successfully implemented. Although the stagnant urge of some effective performance evaluation mechanism is unfulfilled. With this thought, a performance evaluation model is proposed to examine the implementation performance of TQM practices in the automobile and automotive establishments in India. By this model, a company may analyze the effectiveness as a performance measure of implied TQM practices by considering attainment proportion to implement and significance proportion to fix priority in implementation. Further, the established Inclusive Effectiveness Model is verified by statistical control chart. Also, an industry is selected arbitrarily to check the applicability of the conceived model.

Exploring key dimensions of E-service quality: A case of Indian banking industry
by Vivek Agrawal, Vikas Tripathi, Anand Mohan Agrawal
Abstract: Purpose: Consumers become more aware of a companys performance when the service provider adopts technology. This holds especially true when financial transactions are involved (e.g. when availing of services such as banking). In such situations, consumers demand more reliable services and greater security in financial transactions. Thus, banks need to improve the quality of e-services provided by them. However, to improve online service quality (e-service quality), it is important to understand the factors influencing e-service quality. The present paper seeks to identify e-service quality dimensions relevant to the banking industry. It attempts to critically analyze the relationship amongst them so that policy makers can focus on relevant parameters to improve the e-service quality in banking.
Design/methodology/approach: Interpretive structural modeling (ISM) approach has been applied in this study for modeling the e-service quality dimension. The model would assist policy makers in improving and developing services provided electronically by banks. Further, identification of dimensions would help decision makers improve these dimensions.
Findings: The major findings of this study are to prioritize the strategic dimension in reducing the risks associated with e-service quality. Research shows that there exists a group of dimensions with high driving power and low dependence requiring maximum attention and possessing strategic importance.
Limitations/implications: Policy makers in the banking industry would benefit from this classification in that they would be able to avail themselves of a tool that would enable them to differentiate among the different dimensions affecting e-service quality of online banking, and understand the underlying relationships. Such understanding would help them identify and focus on key dimensions that are important for providing better services online, and building a strong customer base.
Originality/value: The hierarchical presentation of dimensions and their classification into driver and dependent categories is a unique attempt that has been made in context of e-service quality in the Indian banking industry.

A Cooperative Covering Problem under Disruption Considering Backup Coverage
by Ladan Hazrati Ashtiani, Mehdi Seifbarghy, Mahdi Bashiri
Abstract: In this paper, we study the location of emergency centers considering cooperative and backup coverage while natural disasters occur which can result in facility disruption. In this regard, a reliable version of cooperative covering problem is presented considering two types of candidate sites i.e. reliable and unreliable. To achieve a fortified system against disaster, reliable candidate sites are selected from areas which are far away from the disaster harms. Furthermore, backup coverage is considered to compensate unsatisfied coverage of the demand zones due to facility disruption. The performance of the model is investigated solving numerical examples with different approaches utilizing a commercial software. The results confirm accurate performance of the model. They also show that both facility failure and backup coverage considerations lead to a more efficient network by incurring some additional cost.
Keywords: Backup coverage; Cooperative covering; Disruption; Natural disaster; Reliability.
Failure analysis of automobile spares in a manufacturing supply chain distribution centre using Six Sigma DMAIC framework
by S. Srivatsa Srinivas, V. Raja Sreedharan
Abstract: The spares distribution centre is an important member of a manufacturing supply chain where the automobile components are packaged and distributed to customers and retail units. Though the components do not undergo processing in a spare parts centre, various other operations are performed during distribution that contributes to component failures. The Six Sigma DMAIC framework is for the analysis of the failures effectively. The different causes of rejections are generated using the Cause and Effect diagram and each of these causes are validated with the help of experiments and other tools. The root cause of this problem arising in the distribution centre is identified to be the packing method. A solution to the existing cause of the problem is implemented with minor variations in the current packing method and the results are discussed. A structured follow up plan for continuous improvement is also suggested.
Keywords: Spare parts distribution unit; failure analysis; Six Sigma; DMAIC.

by Houssem Felfel, Omar Ayadi, Faouzi Masmoudi
Abstract: In this paper, a multi-product, multi-period, multi-site supply chain production and transportation planning problem under customer demand uncertainty is considered. The problem is modeled using a multi-stage stochastic programming model taking into account the production amount, the inventory and backorder levels as well as the quantity of products to be transported between the different plants and customers in each period. Risk Management is also addressed by incorporating a risk metric into the stochastic programming model which leads to a multi-objective optimization model. The objective aims simultaneously to maximize the expected profit as well as the worst case profit. A real example from textile and apparel industry is studied in order to illustrate the effectiveness of the proposed model and the robustness of the supply chain planning solutions.
Keywords: multi-site; supply chain planning; multi-stage stochastic programming; textile; risk management.

Coordination and Pricing Decisions in a Closed-Loop Supply Chain
by Hamid Faramarzi, Ignacio Castillo
Abstract: This paper investigates coordination and pricing decisions in a closed-loop supply chain (CLSC) with a manufacturer (who solely produces the new product), a remanufacturer, and a retailer (who sells both new and remanufactured products). We also consider a supplier who provides both the manufacturer and remanufacturer with new parts. In practice, the new and remanufactured products are vertically differentiated: generally consumers perceive the remanufactured product as of a lower quality. This key characteristic is captured in our research. The implication is that CLSC members are required to price the new and remanufactured products accordingly. Moreover, we consider three coordination structures: manufacturer and retailer coordinated (MRC), retailer and remanufacturer coordinated (RREMC), and a completely decentralized (CD) channel, which serves as a benchmark. In this paper, we are able to analytically show how the optimal prices and quantities for new and remanufactured products at the retailer level compare with each other across different CLSC coordination structures. In addition, through an extensive numerical study, we show how the total CLSC profits and the suppliers profits compare with each other across these structures. We also investigate the sensitivity of our results to the quality of returns and consumers perceptions. We find that both the CLSC and the supplier enjoy the highest profits from the coordination between the retailer and the manufacturer. In addition, we show that the coordination between the retailer and the remanufacturer results in the lowest profits for the CLSC members, but not necessarily the lowest for the supplier.

Supply Chain Coordination under Revenue-Sharing Contract with Value-Added Services considering Risk-Attitude of the Customers
by Nafiseh Shamsi Gamchi, S. Ali Torabi
Abstract: In this paper, we address a dual-channel supply chain in which a manufacturer sells multiple products via both a direct channel (like an online market) and indirect channels (e.g., through some retailers). Different service contracts with different risk-attitudes are offered by different channels as product warranty. A decentralized and a centralized model (under revenue-sharing contract) are discussed to obtain the sale price of each product at each channel. Two coordinating factors, namely the wholesale price and the fraction of revenue, are obtained as decision variable and using Shapley Value respectively. Finally, a numerical example is presented to illustrate the applicability of the proposed decision models.

Predicting the Behavioural Intention to adopt Lean practices: An Empirical Study in the Manufacturing Industry
by Swati Alok, Aman Kabra, Anirudh Mudam
Abstract: The purpose of this paper is to test the efficacy of Ajzens Theory of Planned behaviour (TPB) in predicting lean adoption practices, which holds that intention is strong determinant of the behaviour. With this cue, a study was conducted among the employees of Awarpur Cement Works, Maharashtra (UltraTech Cements, Aditya Birla Group).
A questionnaire using Ajzens guidelines was administered to the employees. Prior to the main study, qualitative research was conducted to identify the various advantages, facilitators and barriers in the implementation of lean management practices among the target population. Seven variables of Theory of Planned Behaviour (TPB) comprising Perceived direct advantages (PA), Perceived indirect advantages (P_IA), Perceived disadvantages (P_DisA), Perceived usefulness (PU, ) Subjective Norms of peers/supervisor (SN), Self-Efficacy (SE) and Facilitating Conditions (FC) have been studied in relation to lean adopting intentions. The multiple regression models were employed using the SPSS software to investigate the effects of the constructs on lean adopting intentions based on the 110 responses.
The results indicated that TPB variables were able to capture 59.2% of the variance in predicting lean adopting intentions. FC, SE and PA were the strongest, positively related predictors while P_DisA and PU were the strongest, negatively related predictors of the lean implementation intentions. Also, education was found to be a significant factor, with the motivation to adopt lean behaviour being higher for employees with higher levels of education.
The originality of the paper lies in identifying four constructs to define the attitude towards lean methods and contributes to the research into the key antecedents that affect lean adoption practices.

A new multi-objective/product green supply chain considering quality level reprocessing cost
by Parvaneh Loni, Alireza Arshadi Khamseh
Abstract: Green supply chain is among the hottest recent research subjects in supply chain management which not only optimises the costs and service levels during a time period all over the chain, but also considers effect of emission of CO2 greenhouse on the overall value of supply chain for sustainable development. Therefore, in this paper, a Bi-objective, multi-stage, multi-product quadratic optimisation model was proposed by taking into account the quality level of the purchased materials plus their reprocessing extra costs to system in stochastic mode and environmental costs of CO2 emission. Here we also consider both straight and step by step transportation in supply chain network design. Since the problems is NP-hard, a priority-based genetic algorithm model was proposed. In this paper, three methods including BOM , LP-metric and Elastic BOM were applied to solve small data, whereas, Elastic BOM offer larger solution space and more justified solutions. Hence, for solving large data, three priority-based genetic algorithm corresponding to MODM techniques were utilised. Then, by using TOPSIS for small and ANOVA for medium and large problems, the optimum procedure for balancing the existing costs and CO2 emission in the chain was selected.
Keywords: ¬Green supply chain, priority-based genetic algorithm, MODM techniques, CO2 emission
A Review on Industrial Applications of TOPSIS Approach
by Santosh Kumar Yadav, Dennis Joseph, Nasina Jigeesh
Abstract: Technique for order preference by similarity to an ideal solution (TOPSIS) is a multi-attribute decision making technique, used to evaluate alternatives and find an ideal solution. Practically it has been successfully applied to identify the best alternative for decision making process from a finite set of alternatives. Its applications cover industries and many areas like selection of suppliers/processes/designs/locations/standards and many others, and it can be used for evaluation of the performance of different entities. TOPSIS helps in ranking the alternatives through a set of select attributes of a particular issue like performance, quality and safety. In view of the significance of TOPSIS in several industries to prioritize the alternatives, this paper is intended to highlight various important industrial applications of the method with the help of detailed review of literature. The main purpose of the paper is to detail the usefulness of TOPSIS in selecting the best out of a set of numerous alternatives in different industrial scenarios. It describes TOPSIS applications in different areas automobile, mobile, and information technology, manufacturing, biological and behavioral. The different prioritization objectives that are addressed in the paper include selection of supplier/brand/gene/material/vehicle/location/team member, evaluation of service quality/customer satisfaction/financial performance and investigation of causes for organizational strengths and weaknesses and even suicide thoughts. In order to detail the approach TOPSIS follows, a hypothetical example is presented. It presents the step-wise derivation of solution by using TOPSIS. A total of six alternatives have been considered in the example along with five criteria three are benefit criteria and remaining two are cost criteria. Using TOPSIS, based on relative closeness to the ideal solution, all the six alternatives have been ranked.

Supply Chain Performance Measurement: A future research agenda for acquiring competitiveness through the implementation of leagile manufacturing paradigm
by R Maharaja, S.R. Devadasan, M Sakthivel
Abstract: In this paper, the literature survey conducted to study the state of the art research and pinpoint the future agenda of research on leagile manufacturing is reported. The information and knowledge derived by conducting this literature survey have indicated that the researchers have been enunciating the determination of a juncture which is called as decoupling point to determine the proportion of lean and agile manufacturing implementation in the concerned traditional manufacturing companies. These researchers have also found that supply chain management plays a crucial role in ensuring the successful implementation of leagile manufacturing paradigm. The ultimate results of conducting this literature survey revealed that efforts are yet to be made for measuring the process of achieving leagility through supply chains. At this moment, researchers are required to contribute a model for measuring the performance of leagile supply chains. In this context, this paper ends with suggesting the steps to be followed for developing leagile supply chain measurement model. Such model will be useful for the engineers and managers for strengthening the weak spots to successfully implement leagile manufacturing paradigm in traditional manufacturing companies and acquire competitive strength.
Keywords: Leagile manufacturing paradigm, supply chain management, decoupling point, leagile supply chain and supply chain performance measurement.
Analyzing NEH and a Few Other Similar Permutation Flow Shop Scheduling Heuristics using Taillards and Valladas Benchmarking Problems
by Baskar Amaladosan
Abstract: This paper analyzes the performance of the NEH and five more similar heuristics proposed by the author using Taillard benchmark problems (120 in numbers) proposed in 1993 and new hard benchmarks (480 in numbers) proposed by Eva Vallada et al. in 2015. Two more initial ordering of jobs are considered besides the original, which orders the jobs in non increasing order of the total processing times. The first one is according to non increasing order of average processing time and standard deviation of their processing times proposed by Dong et al. in 2008 and the other one being pertinent to non increasing order of average processing time, average machine idle time and the standard deviation of their processing times. The performance of various heuristics and different ordering of jobs are also analyzed using real time data collected from a plant manufacturing cold drawn seamless (CDS) tubes. The results indicate that two heuristics proposed by the author perform slightly better than NEH.

Fundamental Principles of the Toyota Way and the Theory of Constraints: Comparative Analysis and Synthesis
by Guilherme Venanzi Almeida, Fernando Bernardi Souza, Humberto Rossetti Baptista, Mahesh C. Gupta, Renato Campos
Abstract: Several researchers have attempted to understand the essence of the principles that support Toyota Way and Theory of Constraints management philosophies, because they recognize such principles as central to explain their performance. For this reason, the objective of this study is to identify similarities and differences between the Theory of Constraints and the Toyota Way from a perspective on their essential fundamentals, as much as to identify gaps as opportunities for integration. From the methodological point of view, this is a theoretical-conceptual study based on the literature. Even though important differences have been identified, the results lead to significant similarities between the two forms of management. Such similarities can be the basis for the adoption of hybrid alternatives, which can expand their limits and favor their applicability as an integrated solution.

Energy Consumption Assessment and Optimization of Manufacturing Sectors by Clustered Stochastic Data Envelopment Analysis
by Ali Azadeh, Sara Motevali Haghighi, Abbas Keramati
Abstract: This paper presents an approach based on stochastic data envelopment analysis (SDEA) and clustering analysis to assess and optimize energy consumption in manufacturing sectors. Fossil fuel consumption, electricity consumption, total weighted production, and average weighted boiling point are considered as key performance indicators in this study. SDEA is tailored and used to alleviate data uncertainty and randomness for energy consumption problem. Clustering analysis is used to achieve homogeneity between decision making units (DMUs). Noise and sensitivity analyses are performed to select the best α of SDEA model and also to identify the most important shaping factor. The results show that total weighted production is the most influential shaping factor in this study. Also, the distance between ideal and real value of each factor is estimated in order to help decision makers in improving performance. Finally, the proposed model is validated and verified through a robust analysis. The proposed approach would help decision makers to have a comprehensive understanding of energy consumption in manufacturing sectors. To the best of our knowledge, this is the first study to assess and optimize energy consumption of manufacturing sectors by clustered stochastic data envelopment analysis.

A Stochastic Scheduling Approach to Minimize the Number of Risky Jobs and Total Probability of Tardiness
by Gokhan Eglimez, Gursel Suer, Aslican Arinsoy
Abstract: In this paper, single machine stochastic scheduling problem is addressed where jobs have probabilistic processing times and deterministic due dates. In classical scheduling literature, a job is called tardy if it is completed after its due date; otherwise its called early. However, in probabilistic concept, a job can have a nonzero probability of tardiness. To capture this situation, a stochastic non-linear mathematical model is developed. The objective is to minimize the expected number of tardy jobs and the total probability of tardiness. Experimentation is performed with datasets having varying number of jobs from 10 to 100. Results are compared with deterministic model. The proposed approach resulted in a significant decrease in the number of risky jobs and the total probability of tardiness. In addition, as the variance of processing times increased, the proposed stochastic approach provided safer schedules in terms of the total probability of tardiness.
Keywords: Stochastic scheduling; single machine; probability of tardiness; nonlinear optimization; expected number of tardy jobs.

Abstract: In this paper three algorithms are designed to solve the bi-team orienteering problem with time window (BTOPTW) in which the aim is to minimize the total travel cost as well as maximizing the score gained by the salesmen. In one of them, a greedy algorithm tries to select the best solution from the initial solutions by a greedy procedure. The other algorithm constructs a solution by the GRASP and searches its neighbour solutions. The last algorithm which is presented in this text is an extended version of previous algorithm augmented by the NSGA-II. Evaluation of the algorithms performances is done by comparing the results of the algorithm with the result of the improved augmented epsilon constraint (AUGMECON2) approach for small sized instances. For large instances the algorithms are compared by some measures such as non-dominated Pareto size (NPS), spacing metric (SM), generational distance (GD), inverse generational distance (IGD) and set coverage metric (CS). The validity of the model is analyzed by sensitivity analysis and in the computational experiments section. The instances are solved by improved augmented epsilon constraints, greedy algorithm, multi objective based on GRASP, the hybrid algorithm of the GRASP and NSGA-II. The results confirm that the greedy algorithm performs better than the others regardless of computational time; however, NSGA-II algorithm has got satisfactory efficiency in an acceptable computational time.

Goal Based approach for Environmentally Sustainable Stochastic Procurement Problem
by Harpreet Kaur, Surya Prakash Singh
Abstract: Due to volatile business environment, manufacturing firms regularly faces huge challenges in adapting to market uncertainties, increased competition and environmental legislations imposed by governments. Therefore, there is a need to capture the uncertainties in various parameters while keeping firms own interest of maximizing profitability by minimizing overall costs. This paper considers a multi period procurement problem of a firm operating in a carbon sensitive and uncertain business environment procuring multiple items from multiple vendors using multiple carriers. The firm is having limited carbon quota exceeding which carbon credits must be bought. The paper proposes a goal based approach for environmentally sustainable procurement problem (Goal_ESSP). The Goal_ESSP model addresses the firms interests by putting various targets as goals and establishing an optimal trade-off among various goal targets. The proposed Goal_ESSP model considers stochastic parameter to capture uncertainties. Finally, the Goal_ESSP model is demonstrated using three illustrations which are solved in LINGO 10.

Does Ownership Matter in Service Quality?
by Iman Adeinat, Charles Gregg
Abstract: The aim of this study is to assess the level of service quality by controlling for ownership and geographical location in a franchise system. A survey was distributed to customers at three outlets in the same chain all owned by the same franchisee and all located in the Midwest region of the US. The survey questions covered five dimensions of quality: tangible, reliability, responsiveness, assurance, and empathy. The findings showed that customers had a positive response toward service quality and that there was no statistical difference in the service quality among these outlets since service quality is more likely to be emphasized and monitored closely. In addition, the results show customer satisfaction and loyalty are a result of higher service quality.
Keywords: customer satisfaction; DINESERV; franchise; service quality.
Inter-organizational Learning in the Context of Third Party Logistics Services
by Hokey Min, Haozhe Chen, Soonhong Min
Abstract: In this era of knowledge economy, knowledge can be a differentiator for the firms business success. In this regard, the 3PL is no exception in that it plays a critical role in funneling information flows across firms in a supply chain as a logistics integrator. These information flows facilitate inter-organizational learning between the 3PL and its client firm. Organizational learning, however, may vary from operational to strategic decision-making hierarchy, which leads to either competitive parity or competitive advantage, respectively. Taking a dyadic perspective, this paper provides a conceptual framework theorizing inter-organizational learning potential between a third-party logistics provider (3PL) and its client firms. Within this framework, it posits that a firms orientations toward logistics outsourcing and organizational learning together influence its business performance and competitiveness. This paper also develops a series of propositions regarding inter-organizational learning between the 3PL and its multiple client firms that can be a basis for future empirical studies and theory building. Based on these propositions, we may argue that an effective learning strategy of the 3PLs in a proper combination of the firms relationship orientation and learning orientation is a key to the success of logistics outsourcing.
Keywords: Third-party Logistics; organizational learning; knowledge transfer.
Quality Management System and Sustainability: A Malaysian Perspective
by Amjad Khalili, Md Yusof Ismail
Abstract: During recent times numerous studies have examined the interrelationships among Quality management system (QMS) and the sustainable performance (SP) of organizations, but none of the approaches addressed the issues in a holistic manner. Moreover, there is a very little empirical evidence concerning sustainability initiatives and how the QMS affects SP. This paper aims at investigating the linkage among the QMS and the SP of manufacturing sector of Malaysia in a complete form by applying techniques from both the SPSS and Structural Equation Modeling (SEM). The developed model with the relevant hypothesis is examined in 329 industries certified with QMS in two phases. The first phase of this study includes semi-structured interviews with Malaysian industrial managers to examine the models applicability. While in the second phase structured survey questionnaire is designed in order to obtain quantitative data for the empirical investigation. From the interviews with twelve (12) managers, it implies that practices by local manufacturers are consistent with the developed model. Subsequently, the PCA and CFA were conducted to explore and confirm the model by validating the hypothesis which reveals that SP is not affected by QMS. Thus this paper has contributed in two ways: first by using the triangulation design approach for collecting the primary data and secondly by measuring multiple targeted sectors under the manufacturing environment.

by K. Sivananda Devi
Abstract: The current focus of modern manufacturing is to develop a mechanism which converts the raw material to the finished goods with zero wastage and at least-cost. Lean manufacturing approach is considered as a successful business strategy which employs minimization of process variability and non-value added activities (waste). Value Stream Mapping is one of the advanced tool in lean manufacturing concepts. Such approach has not been explicitly practiced in wet grinder manufacturing system. An attempt has been made in this paper to systematically evaluate Current State Mapping(CSM) and implement Future State Mapping(FSM) in a wet grinder manufacturing system. Current State Mapping describes the present Value Stream Mapping and other related activities that influences the Value Stream. VSM helped the company to completely understand the process of value added and non-value added activities in the system. The objective of this study is to minimize the non value added activities, lead time of the product to meet the customer demand by achieving the required TAKT time. The current state mapping has been developed by careful observation of cycle time, change over time and non value added activities. The FSM is arrived by incorporating various improvements in the assembly line and improving value added activities.

Modeling and Solving a Bi-objective Single Period Problem with Incremental and All Unit Discount within Stochastic Constraints: NSGAII and MOPSO
by Mahsa Najimi, Seyed Hamid Reza Pasandideh
Abstract: One of the perennial problem in inventory control is single-period problem which is called newsboy problem. In this paper, a single-period problem is developed. The problem is presented by a bi-objective multi-product multiple constraints to maximize the expected profit as well as minimizing the whole warehouse space. Incremental and total discount policies are considered in purchasing the items.In order to optimize the objectives, three types of constraint are presumed for each product which are the service level, budget and required warehouse space. In addition, the decision variables are real and the problem will be modelled in type of a mixed integer nonlinear programming. Moreover, meta-heuristic algorithms are utilized to solve the model. Non-dominated sorting genetic algorithm II (NSGA-II) and multi-objective particle swarm optimization are proposed to find the Pareto front as near-optima solutions. To achieve better results, RSM method is applied to calibrate the flexible parameters of both algorithms. In final, t-student tests are employed to compare the performances of proposed algorithms in terms of solution qualities.

Fixed vs. Negotiable Price; Who Wins the Market: An Evidence from Pakistan
by Asad Javed, Muhammad Yasir, Faisal Sajjad
Abstract: Price is an important P of marking which represents the amount of cost which customers have to pay. There are different ways in products are priced. Prices of some products are fixed and some are negotiable. This paper compares the effect of fixed pricing and negotiable pricing on purchase decision of locally manufactured products. The paper also compares the effect of different demographic variables on fixed and negotiable price. The results of our empirical study, conducted on locally manufactured apparels, reveal that people evaluate fixed prices more favorably as compared to negotiable price. Furthermore, it was found that demographic variables i.e. education and income affect negotiable price, and people with different levels of education and income had differences of opinion in evaluating negotiable price. However, the majority of respondents were in favor of non-negotiable/fixed price. Hence, it could be concluded from the results that if organizations shift from negotiable price to fixed price, the inclination of customers towards their products increases. This was found to be particularly true in the context of locally manufactured products where both fixed and negotiable pricing practices are prevalent. Finally, the study concludes that sellers of locally manufactured apparels in particular and fast moving consumer goods in general can significantly improve their sales volume by shifting to non-negotiable/ fixed price policy.
Keywords: fixed price; negotiable price; demographic variables.
Using weather data to improve demand forecasting for seasonal products
by Flora Babongo, Ari-Pekka Hameri, Valerie Chavez-Demoulin, Tapio Niemi, Patrick Appelqvist
Abstract: In seasonal business, manufacturers need to make major supply decisions up to a year before delivering products to retailers. Traditionally, they make those decisions based on sales forecasts that in turn are based on previous seasons sales. In our research, we study whether demand forecasts for the upcoming season could be made more accurate by taking into account the weather of the previous sales season. We use a 10 year data set of winter sports equipment (e.g. skis, boots, and snowboards) sales in Switzerland and Finland, linked with daily meteorological data, for developing and training a generalized additive model (GAM) to predict demand for the next season. Results show a forecasting error reduction of up to 45% when including meteorological data from the past season. In our case, the value of this reduction in the forecasting error corresponds to around 2% of total sales. The results contribute to the theory of stochastic inventory control by showing that taking into account external disturbances, in this case the fluctuations in weather, improves forecasting accuracy in situations where the lag between ordering and demand is around one year.

PSO Based Harmony Search Algorithm (PSO-HSA) to Aggregate Production Planning Under Possibilistic Environment
by Md. Sanowar Hossain, Khan Mohaimanul Islam
Abstract: This paper work developed PSO based HSA, a non-traditional optimization technique to find globally optimized solutions of complex problems more efficiently than traditional techniques. The proposed technique named as Particle Swarm Optimization based Harmony Search Algorithm (PSO-HSA) is developed on the structure of HSA and a few concepts of PSO algorithm are used to modify the improvisation processes. The aim of PSO-HSA is to incorporate multiple improvisation processes as well as total utilization of all the possible solution sets in improvisation step. Again the elimination the complexity of predefinition for various algorithm parameters is also considered. At the same time this paper demonstrated possibilistic environment based multi-product, multi-period aggregate production planning. The proposed approach uses a triangular possibility distribution for handling all the imprecise operating costs, demands, and also for the capacity data. The proposed approach uses the strategy of simultaneously minimizing the most possible value of the imprecise total costs, maximizing the possibility of obtaining lower total costs and minimizing the risk of obtaining higher total costs. Here the authors also employed genetic algorithm approach for solving the APP problems and analyzed the performance and validity of the proposed PSO-HSA approach. For reinforcing & accelerating the decision making for the decision maker a case study was considered in a Ready Made garment company in Bangladesh and the problem solved by MATLAB.

Conceptualizing the Framework for Effectiveness of Customer Value Co-Creation in Service Innovation
by Tejas R. Shah
Abstract: The involvement of customers as co-creators in new service innovation is increasingly being suggested as a successful strategy to improve the success rate of new services. Value-in-use is a central theme for the service-dominant logic because the customer is always a co-creator of value. Co-creation involves customer engagement in the creation of offerings through ideation, design and development. The objective of this paper is to develop the framework for successful development and implementation of Customer Value Co-Creation process in service innovation. Based on literature review, three phases of value co-creation have been developed. First, Motivation for customer value co-creation is one of the important aspects to consider by a service firm. Extrinsic and intrinsic motivations play a key role for customer motivation to participate. Second, customers role in value creation process have greater been developed. Customer experience during interaction becomes central to the value creation process. Customer participation in value creation process is divided into two parts: participation behavior and citizenship behavior. Third, criteria for superior value co-creation process have been developed. This research brings the framework that motivation for value co-creation creates positive impact on value co-creation process, which in turn leads to generate positive value co-creation experience.

A mathematical model for collecting and distributing perishable products by considering costs minimization and CO2 emissions
by John Willmer Escobar, Rafael Tordecilla Madera, Andrés Polo Roa, Nicolas Clavijo Buriticá
Abstract: This paper considers the problem of allocating vehicles to collect and distribute fruit to producer associations in Colombia. In particular, the problem seeks to determine the optimal allocation of vehicles for fruit collection minimizingboth total transportation costs and CO2 emissions. This problem has multiple objectives, and the well-known ε-constraint method has been used as solution technique for the proposed mathematical models. The efficiency of the former methodology has been tested by using a case study involving the distribution of blackberry (Rubus glaucus) by an association of producers in Cundinamarca Department, Colombia. In particular, we considered 12 different scenarios related to supply levels, route outsourcing, and collection frequency. The results show the efficiency of the proposed methodology in solving vehicle allocation problems related to collection and distribution. The case study reveals that, in general, collecting fruit three days/week yields lower costs and fewer emissions than performing collections four days/week. Furthermore, increased supply leads to greater differences between costs and emissions.

Analyzing interactions of agile supply chain enablers in Indian manufacturing context
by Bharat Singh Patel, Cherian Samuel, S.K. Sharma
Abstract: Agility is the ability of an organization to respond quickly against unpredictable business environment like changes in market behavior and customers demand. Supply chains need to be agile in order to survive in such a business situation. This challenge can be met with agility in-built in supply chains. Agility of the organization depends upon large number of variables. These variables can be called as Agile Supply Chain (ASC) enablers. It is important for the organization to identify these variables which can be deployed collectively to make the organization, a profit making one, in the competitive market place. Enablers of agile supply chain are the concerned technologies and methodologies which are very much significant to achieve agility. It is not economical and efficient to give same focus and attention to all agility variables. To overcome this problem Interpretive Structural Modeling (ISM) is used to develop a hierarchy of enablers. In the present paper, ISM is applied to derive interrelationships among agile supply chain enablers that influence supply chain agility. Further Rank Sum Weight (RSW) method is used to allocate the weights to enablers. It is seen from literature that ISM does not reveal any weight associated with enablers. An integrated approach of ISM and RSW can help to overcome this limitation. ASC enablers have been also categorized according to their driving power and dependence using MICMAC analysis.

by Amay Yeravdekar, Abhishek Behl
Abstract: The advancements in the field of sports, especially cricket, are multidimensional. Of the various aspects of cricket, branding and commercialization are two areas that have received insufficient attention, both theoretically and empirically. The present study aims to develop a conceptual framework using Total Interpretive Structural Model to develop a hierarchy of enablers for commercialization of cricket. The research also discusses the reasons for inter linkages between the enablers. The study accounted for 11 enablers and discovered that facility given at the school or primary level is the key enabler for commercializing the game. The study also found out that state-of-art infrastructure, scholarships given to the players, and motivating incentives from the government are some of the other important enablers that could act as catalysts in enhancing the positive aspects of commercialization in the game. The study lays foundation for similar discussion for other sports and for empirically testing the formulated model.

MEASURING STUDENTS EXPECTATIONS OF SERVICE QUALITY OF A HIGHER EDUCATION INSTITUTION IN A LONGITUDINAL DESIGN
by Domingos Fernandes Campos, Guido Salvi Dos Santos, Felipe Nalon Castro
Abstract: This study presents changes in undergraduate students' expectations of service quality, regarding 33 attributes of services provided at a private HEI, over a longitudinal investigation. The course directors did not intervene intentionally, directly or in any significant way that would alter the conditions under which the services were offered. Data collection was performed at five different times, addressing the same group of students. The assessment of the expectations shows that, over time, students undergo changes in their perceptions, although the relative importance of the attributes does not undergo a radical repositioning. Senior students tend to be more demanding than freshmen. The information obtained enables managing directors to align with emerging paradigms, and effectively direct resources for retention and loyalty, and to attract customers by meeting their expectations at different stages of interaction with the institution.

Application of fuzzy analytical network process for the selection of best technological innovation strategy in steel manufacturing SMEs
by Kiron K.R., Kannan K
Abstract: The success of small and medium enterprises (SMEs) depends mainly on its ability to innovate. Earlier studies revealed that among various types of innovation, technological innovation is the most important. Selection of the best alternative for improving technological innovation thus gains vital importance and it is a multi-criterion decision making (MCDM) problem. A model was developed for steel manufacturing SMEs to improve their technological innovation capability. The model employed fuzzy analytical network process (FANP) for the selection of the strategy for improving the technological innovation capability. The idea of applying FANP for the selection of best alternative to make an SME innovative is novel. By the developed model, studies were conducted in three small scale steel manufacturing enterprise. Among the four strategies, it was found that the best strategy for all the three organisations is the cooperation approach. Cooperation with other similar enterprises, co-operation with research and other technological institutions is found to be important for the SME. The result of the study is having utmost importance in framing the strategies for SMEs. It helps the decision makers of SMEs to create an organisational culture which can foster technological innovation.

Abstract: This paper presents four new enhanced DE-based algorithms for solving multi-depot vehicle routing problem with multiple pickup and delivery requests (GVRP-MDMPDR). Two enhanced DE algorithms are based on subgrouping idea and two are based on the idea of strategy switching. The four enhanced algorithms are: subgrouping mutation differential evolution (SGMDE), subgrouping crossover differential evolution (SGCDE), switching mutation differential evolution (SWMDE), and switching crossover differential evolution (SWCDE). All enhanced algorithms are compared to the classical DE algorithm for solving GVRP-MDMPDR by using published benchmark test problems. The results show that algorithms SGMDE, SGCDE and SWCDE outperform classical DE algorithm. Furthermore, it found that the enhancement in the crossover process is more effective for improving DE performance than enhancement in the mutation process. The combination of the solution representations SD1 and SD3 with the DE-based algorithms also found new best known solutions in 25 out of 30 test problem instances.
Keywords: Differential evolution; generalize multi-depot vehicle routing problem with multiple pickup and delivery requests; subgrouping; switching.
Performance measurement of the leagile supply chain
by R. Maharaja, S.R. Devadasan, M. Sakthivel, R. Murugesh
Abstract: In this paper, a model is contributed to enable the companies to measure the performance of the leagile supply chain. Leagile supply chains are incorporated with the principles of lean and agile manufacturing paradigms. An unique feature of this measurement model is that it is incorporated with the provision to accommodate the decoupling point of leagility. Decoupling point refers to the point that separates leanness and agility. In order to utilize this measurement model, responses against a questionnaire are to be gathered to measure the leagile supply chain performance of the company. The data gathered by getting those responses are substituted in a mathematical model to calculate the leagile supply chain performance index of the company. By referring to the leagile supply chain performance index, the company can strive to move towards imbibing agility for acquiring competitive strength.
Keywords: Leagile production paradigm; lean manufacturing; agile manufacturing; supply chain management; decoupling point.

Macro and micro logistic aspects in defining the parts-feeding policy in mixed-model assembly systems
by Maurizio Faccio, Mauro Gamberi, Marco Bortolini, Francesco Pilati
Abstract: The handling activities within mixed-model assembly systems deal with two different logistic levels of the production environment. The micro-logistic level includes movements of parts across each assembly station due to pick to assembly activities. The macro-logistic level includes movements of parts within the supermarket and to deliver the stock-keeping units to the assembly stations. The most frequently adopted part-feeding policies, i.e. kanban system and kitting system, strongly influences both logistic levels with opposite effects. The former continuously refills the assembly stations; the latter prepares and delivers kits of components for each product. Moving from kanban to kitting system the time spent at the macro-logistic level increases. On the contrary, the time spent in part handling at the micro-logistic level decreases when moving from kanban to kitting system. Effective trade-offs are encouraged. This paper analyses the two introduced part-feeding policies, including hybrid possibilities, through an operative total handling time comparison model. The findings from five industrial cases belonging to different sectors and a global simulation analysis are discussed. Conclusions about the impact of some of the most important logistic variables of the production system to the whole performances drive the industrial practitioners in the part-feeding policy selection.
Keywords: part-feeding policy; kanban; kitting; hybrid system; assembly system; time model; just-in-time.
A new mathematical model for non-fixed destination multi-depot multiple traveling salesmen with time window problem
by Hany Seidgar, Mohammad Taher Shirafkan, Nikbakhsh Javadian
Abstract: Consider the problem of having a team of cooperative and autonomous vehicles to repeatedly visit a set of target locations and return back to their initial locations. This problem is known as multi depot multiple traveling salesman problems (MD-MTSP), which applies to several mobile robots applications. The non-fixed destination multi-depot multiple traveling salesmen with time window problem (MmTSPTW) is a generalization of a well-known MmTSP with considering time window for each node in a tour. The salesmen also are not forced to return to their starting depot. This problem is of great complexity and belongs to NP-complete class of problems. In this paper, a new mathematical model is proposed for MmTSPTW by considering waiting penalties and time window is defined for each depot (city). The salesmen only can service the customers within these time windows and also some penalties are considered for any deviation of start time. The objective function of problem is to minimize the total costs and penalties of the tours.
Keywords: Multi depot multiple traveling salesmen; Time windows.

Analysis of patient flows in Elective Surgery: modelling and optimization of the hospitalization process
by Dario Antonelli, Giulia Bruno, Teresa Taurino
Abstract: Rationalizing costs while guaranteeing a good quality of service is a challenge that healthcare systems are currently facing. In elective surgery departments, as operations can be scheduled in advance, the goal is usually to maximize the utilization index of the operating theatre. Nevertheless, the optimization of a single stage of the process is pointless without an efficient management of the entire routing from income to dismissal. The paper presents Discrete Events Simulation of the actual patient flows in elective surgery exploiting the recovery logs of a hospital department. A UML Activity Diagram of the surgery process together with the collected hospital data have been used to build a stochastic model of queuing network, identify its parameters and conduct different simulated experiments in order to select the solution that best optimizes the performances of the system. The simulation results have shown that there is a large variation in waiting times in correspondence to small variations of the average value of the inter-arrival times. Therefore, solutions that optimize utilization indexes of both beds and operating theatres should consider a concurrent effort to reduce the variance of admittance processes, otherwise the waiting times will lengthen beyond acceptable limits.

Hybrid Cellular Manufacturing System Design with Cellularization Ratio: An Integrated Mixed Integer Nonlinear Programming and Discrete Event Simulation Approach
by Gokhan Eglimez, Bulent Erenay, Gursel Suer
Abstract: This study investigates hybrid cellular manufacturing system design where products with highly similar process routes are formed as manufacturing cells, and products with dissimilar routes are produced in a process layout. A cell similarity threshold, cellularization ratio (C-ratio), is proposed for product assignment to cells and process layout, and integrated into a mathematical modelling-based cell formation approach. The cell formation phase is carried out with the proposed mathematical model. Several case problems are experimented and selected cases are also studied with a newly developed simulation model where manufacturing system performance is also evaluated along with the proposed hybrid cellular manufacturing design alternatives. Results indicated that considering a C-ratio during cell formation can provide higher cell similarity thus better cell formation. The increase in the coverage levels resulted in higher number of cells formed. The proposed approach can be significantly beneficial for manufacturing design decisions where product mix and process complexity are high, and for a hybrid layout that consists of cellular plus process layouts could be implemented.

Product Assignment Using Quadratic Assignment Model in Retail
by Bhawesh Sah, Rohit Titiyal, Desh Deepak Bhandari
Abstract: This paper studies the problem of product assignment in retail. It solves the problem of assigning various products to various in-store locations so that there is increased sale as well as a better customer convenience. Retail managers often work out of intuition to place various products at various locations inside the retail store. While doing so, it is often seen that retail managers ignore the phenomenon of cross-selling. This study quantifies this problem and formulates it as a quadratic assignment problem which is solved by implementing a genetic algorithm. The resulting solution maximises cross-selling among products and at the same time improves customer convenience making it a win-win situation for everybody.
Keywords: Quadratic Assignment Problem; Genetic Algorithm; Cross-selling; Product Assignment.
Managing Quality within Existing Supply Chains: Case studies from Jordan
by Randa Mazzawi, Mohammad Alawamleh
Abstract: In the globalized economy supply chains are of paramount importance to international organizations, thus supply chain management has been intensively studied throughout recent decades to understand the product cycle from the supplier to end customer and within organizations. However, there is a gap in the literature concerning the management of particular parameters such as quality within supply chains. This research investigates methods of measuring quality within existing supply chains using two companies from Jordan as case studies. Two different methodologies were applied in order to be able to conduct this research: direct observation and complete participation. It was noted that quality within the manufacturing supply chain was defined differently than in the service supply chain, thus requiring different actions to be used to measure it.

Improving Organizational Process Input Factors and Company Performance
by Sam K. Formby, B. Dawn Medlin, Charlie Chen, Yongyi Shou, Danuvasin Charoen
Abstract: Enterprise environmental factors (EEFs) and organizational process assets (OPAs) are important inputs for most processes within project management knowledge areas. Lack of consideration of input of EEF and OPA factors may create stakeholder dissatisfaction, invite resistance and create chaotic changes. This study assesses the effect of three important EEF and OPA input factors (project organizational support, project control & contingency planning, and project management processes) on project baseline and planning management. In addition, we investigate how much influence that effective project baseline and planning management have on company performance. Data were collected from ninety-three certified project management professionals (PMPs) registered with the Project Management Institute (PMI) in China. A statistical analysis was conducted to assess the proposed relationships among constructs. Our findings indicated that firms that develop company-wide organizational support systems and company-wide procedures and processes for managing projects within an operations organization are better at overall performance.

PARTICLE SWARM OPTIMIZATION ALGORITHM AND MULTI START SIMULATED ANNEALING ALGORITHM FOR SCHEDULING BATCHES OF PARTS IN MULTI CELL FLEXIBLE MANUFACTURING SYSTEM
by A.N. Balaji, S. Porselvi, N. Jawahar
Abstract: This paper considers the problem of scheduling batches of parts in a multi cell flexible manufacturing system (MCFMS) with sequence dependent batch setup time. The goal is to find the best sequence of batches and hence to minimize the makespan. Two mathematical models are developed namely: Batch availability model and Job availability model. As the problem is known to NP hard, Particle Swarm Optimization (PSO) algorithm and Multi start Simulated Annealing (MSA) algorithm are proposed to solve the problem. The proposed algorithms are validated by testing the bench mark problem available in the literature. In addition to that, eighty problems with various sizes have been generated at random and then the performance of the proposed MSA and PSO algorithms are compared with CPLEX solver. Experimental results show that MSA provides better solution compared with PSO, same solution as CPLEX and very close to Lower bound value provided by CPLEX.

Framing transformation dynamics toward service-orientation: Alternative trajectories of B2B relations
by Inka Lappalainen, Tiina Valjakka, Toni Ahonen, Maaria Nuutinen
Abstract: This article examines the dynamics of complex transformation in value creation logics in B-to-B relations. Based on the literature of servitisation, relationship marketing, and particularly the S-D logic approach, an integrative conceptual frame for structuring provider-customer interaction is built. The frame combines strategic and operational aspects and the perspectives of both parties. It is applied empirically in the multiple case study covering different industries. The results reveal the alternative and parallel trajectories in B-to-B relations of the companies, instead of the previous unidirectional transition approach of servitisation. Furthermore, relating to the topical S-D logic debate the results indicate that the transformation from G-D logic toward S-D logic has been built in as different trajectories. Thus, the conceptual frame explicates the transformation dynamics in terms of value creation logic and mutual dependency between parties. It facilitates particularly SMEs regarding relationship-specific evaluation and development, as well as strategic re-positioning and value constellations.

Creating value with integrated B2B solutions: an empirical study of network maintenance services
by Mikko Pynnonen, Mika Immonen, Jukka Hallikas
Abstract: The objective of this paper is to analyse the structure of a network maintenance service solution and the role of intertwined service functions in creating value for customers. It is proposed that inherent in a solution are service functions highly valued by customers and connected with other service functions. These functions, which are the value drivers of the solution, are referred to in this paper as systemic service functions. It is necessary to identify these service functions in a solutions design to optimise the value of the whole solution. This study presents an empirical case analysis in the field of network maintenance services to enhance the understanding of value creation logic regarding integrated solutions. Social Network Analysis (SNA) and statistical methods will be applied to analyse a survey sample of the network service providers customer companies. The SNA approach serves to describe service function structure from a customer perspective. Regression analysis will be applied to connect the expected value of the service solutions to the expected quality attributes. The findings indicate that systemic service functions commonly relate to routine processes and are bound by a usage context in customer problem-solving domains. This research is expected to open up the structural role of systemic service functions in service solutions and supply chain integration, as well as provide the means to analyse service design and value creation systematically in solutions.

An EOQ Model for Deteriorating Items with Partial Backlogging and Financial Considerations
by Mahsa Ghandehari, Maryam Dezhtaherian
Abstract: One of the important issues in the framework of supply chain is to determine the inventory control policy. In this regard, perishable goods are highly important due to their specific characteristics. In the present study, an inventory model for deteriorating items will be proposed considering constant demand, time value of money, and inflation. Deterioration begins immediately after the entrance of inventory into the warehouse. Delayed payment is allowable and degree of deterioration is fixed. Partially backlogged shortage is also considered and the purpose is to minimize total cost of the inventory system in a finite planning horizon. An exact algorithm was developed in this study for solving the problem and finally some numerical examples were presented. Sensitivity analysis was carried out on some of the important and basic parameters and the results were compared with the state where there is no partial backlogging.
Keywords: Inventory; Deteriorating items; Partially backlogging; Inflation.

An Integrated Approach for Performance Evaluation of Suppliers IN MANUFACTURING INDUSTRIES
by H.ABDUL ZUBAR, M.M.RAVI KUMAR
Abstract: Supplier selection is one of the vital activities in the supply chain and also a major challenge for any organization in the present competitive market scenario. This important strategic decision has a profound impact on the performance of any organization by affecting cost reduction, delivery, service and quality standards of the end products. Different criteria or attributes are involved in the selection and evaluation model and so supplier selection is a multi-criteria decision making (MCDM) problem. The model presented in this thesis aims at aiding the selection process and consists of three phases. In the first phase, criteria for evaluation of suppliers are selected based on literature and Analytic Hierarchy Process (AHP) is applied. The AHP is used to analyse the structure of the problem and weights of each criterion are determined. The second phase involves clustering the available data set into required number of clusters (groups) by k-means algorithm. K-means is a commonly preferred partitional clustering method which generates required number of clusters. The best cluster is selected based on the weighted sum of ratings of the elements. In the third phase, Technique for order preference by similarity to ideal solution (TOPSIS) is performed on the selected cluster. Potential suppliers belonging to the best cluster are ranked according to performance. A sensitivity analysis is then carried out to determine the robustness of the model.
Keywords: supplier selection; analytic hierarchy process; clustering; k-means; TOPSIS; sensitivity analysis.
Green supplier selection problem using TOPSIS extended by D numbers in Tractor Manufacturing industry
by Amin Mohammadi, Soroush Avakh Darestani
Abstract: This research aims to evaluate the suppliers by a combined decision making method with a new concept under uncertainty with d-number structure. Due to the importance of suppliers as a level of supply chain, determining factors for supplier selection decision is of key importance. Criteria in this study all are taken from the most recent articles so far. To consider the issue of environmental indicators related to this case can be considered sharp. In the existing evaluation methods, experts can propose their opinion under uncertainty only in one level. But in new proposed decision making method, experts can proposed their idea about each alternative versus criteria in multi-level simultaneously. Therefore, in this method a group D-number structure with TOPSIS as a compromised decision making method to evaluate supplier selection has been applied. Finally to clearing the proposed method, the tractor company of Tabriz is studied as a case study.

Agility in Healthcare Services: A Systematic Literature Exploration
by Rojalin Patri, Suresh M
Abstract: The objective of this study is to present a systematic literature review of agility in health care covering the essence of published articles, limitations and future research avenues. Its contribution to the body of knowledge is twofold. First, it classifies the literature based on seven parameters: year, country, research method, results, context, limitations and future research direction to provide an overview of the accomplished research works. Second, it highlights the research gap in the current literature and provides direction for future research. In order to accomplish the objective, relevant published articles on agile implementation/ agility in healthcare accessed in databases EBSCO, Proquest and ScienceDirect have been analyzed. The findings suggest that the extant literature has not been able to obtain a strong theoretical grounding in the field, and validation of the proposed theories, models and frame work awaits future research attention. Factors that enable agile performance and concepts as a cost reduction strategy and competency for service innovations are the least explored in the literature. In addition, there is no adequate coverage of the emerging and developing economies such as India and China in the literature. Future research should venture into these lines to enrich the body of knowledge with new insights. Furthermore, generalizability has not been attained in the field which necessitates involvement of quantitative analysis and statistical validation. Apart from this, majority of the research articles have not mentioned the limitations of the study or the direction for future research. This poses a challenge for further research in this field. Thus the lack of extensive exploration of agile literature gives way to a vast area of exploration for future research.
Keywords: Health Services; Agile Services; Agility; Health Care; Agility Literature Review.
Digitisation of traditional product using computer aided design technology: A case study on desiccant compressed air dryer
by D.T. Sunil, S.R. Devadasan, M. Vinod, K.S. Natarajan
Abstract: In order to face the competition, traditional manufacturing companies are required to evolve innovative products by digitising and virtually analysing them in electronic environment. Though digitisation can be carried out by making many technologies, computer aided design (CAD) is the technology that enables economical and compatible digitisation of the products. Hence, today, it is required to explore the way of digitising the traditional products by applying CAD technology. In the context of this realisation, a case study on digitising a traditional product by name desiccant compressed air dryer (DCAR) by applying CAD technology which is presented in this paper was carried out. The procedures adopted to create the CAD models of six subassemblies of DCAR and its assembly by using a CAD software package namely Creo Parametric 2.0 are described. Then the advantage of digitising the traditional products using the CAD technology is described. The article is concluded by stating that utilizing this kind of facilities that are available in CAD software packages will enable traditional manufacturing companies to become agile by quickly adding amazing features that will delight the customer.
Keywords: Digitisation; CAD; Mass customization; Agility; Air dryer.
A Pay-What-You-Want Pricing Model for Restaurants
by Vinaysingh Chawan
Abstract: A new method of pricing, known as Pay-What-You-Want (PWYW) has been successfully used in many contexts in the recent past. Success stories are in restaurants, museums, music albums, software, etc. The method where the buyer selects the price, possibly a zero price, and the seller accepts it, is a bit counter intuitive. Quite surprisingly, the PWYW pricing method has been used successfully, and some businesses have adopted it for selling their goods. We study the economic rationale behind the success of the PWYW pricing method, and analyze different situations using a simple model. Results show that the PWYW pricing method can be successful when there is a large proportion of fair-minded consumers, and a lesser proportion of free-loaders. Also, though a low marginal cost is beneficial for a PWYW method, it is not necessary. Sellers can choose to use PWYW pricing with reference prices that induce, but not bind, consumers to pay an appropriate price. Also, setting a minimum threshold price alleviates the problem of free-loaders, and the PWYW pricing method can be used profitably in the long run.

Hybridizing Plant Propagation and Local Search for uncapacitated exam scheduling problems
by Meryem Cheraitia, Salim Haddadi, Abdellah Salhi
Abstract: The uncapacitated exam scheduling problem (UESP) is a well-known
computationally intractable combinatorial optimization problem. It aims at assigning
exams to a predefined number of periods, avoiding conflicts over the
same period, and spreading exams as evenly as possible. Here, we suggest a new
hybrid algorithm combining the Plant Propagation algorithm (PPA) and Local
Search (LS) for it. PPA is a population-based metaheuristic that mimics the way
plants propagate. To the best of our knowledge, this is the first time this idea is
exploited in the context of UESP. Extensive testing on the University of Toronto
benchmark dataset, and comparison against a large number of new as well as

Mergers and Acquisitions Strategic Fit in Middle Eastern Banking: An NDEA Approach
by Peter Wanke, Md. Abul Kalam Azad, Henrique Correa
Abstract: Banking in Middle Eastern countries is well-known for its heterogeneity, small scale, and regulatory diversity. This paper presents an assessment of the strategic fit of mergers and acquisitions (M&A) in Middle Eastern banks. A network DEA approach is adopted to assess how several types of efficiency scores of the resulting virtually merged banks are impacted by contextual variables: global (merger), technical (learning), harmony (scope), and scale (size) efficiencies. When two banks are virtually merged in our analysis this means that the inputs and outputs of pairs of separate banks are virtually combined to test the efficiencies of the virtually merged entity, in an attempt to better understand the industry. The impact of contextual variables related to the ownership of the bank, its type, and origin is tested using a set of several robust regressions to handle dependent variables bounded between 0 and 1: Tobit, Simplex, and Beta. The results reveal that bank type, origin, and ownership impact virtual efficiency levels; however, the findings also show that harmony and scale effects have a negative impact on merged institutions due to the heterogeneity, regulatory diversity, and small scale size that prevail in the region.
Keywords: Banks; DEA; Mergers and Acquisitions; Middle East; Network; Robust Regression Analysis.

by Saleh Alkhatib, Yazan Migdadi
Abstract: Airlines use different scheduling strategies to manage their operations. Selecting the right scheduling strategy that fit with the airline overall strategy is an issue. In the last few years, several airline scheduling problem studies have been conducted. Most of these studies have focused on the optimization side of the problem. This study aims to identify taxonomies of airline scheduling strategies based on cross-regional airlines analytical study. Scheduling data of 360 worldwide airlines have been collected, analysed, and therefore used to explain and classify airline scheduling strategies into anticipated taxonomies. Data were collected from five regions; Africa, Arab states, Asia and Pacific, Europe, North America and South/Latin America. Standardized ratings were developed and K-Means Clustering analysis was used to develop the taxonomies of airline scheduling strategies. This study revealed that; the adopted taxonomies of airline scheduling strategies are; intercontinental, focused intercontinental, focused/selective international and focused regional scheduling strategies. The widely-adopted taxonomy is focused regional and the least adopted one is the intercontinental. These new taxonomies build the theoretical base for next research areas in airline scheduling, and help airlines to find the best scheduling strategy that fitted their regional characteristics and/or corporate and operational strategies.

Justification of Technology Innovation Implementation in Indian MSMEs using AHP
by Davinder Singh, J.S. Khamba, Tarun Nanda
Abstract: Small enterprises typically make a large contribution to manufacturing employment in poor countries. However, the developmental contribution of most of them is limited to generating subsistence employment of last resort. Hence, in the face of fast labor force growth and limited employment absorption in other sectors, developing country governments have mounted efforts to improve productivity and earnings in these firms. MSMEs constitute 80% of all enterprises globally. They contribute in providing job opportunities, act as supplier of goods and services to large organizations. MSMEs are defined by a number of factors and criteria, such as location, size, age, structure, organization, number of employees, sales volume, worth of assets, ownership through development and technology. The present study explores the significant of various factors contributing towards manufacturing performance enhancement of small firms using Analytical Hierarchy Process.

Emigrants motivation business model for intention to participate in the Malaysia My Second Home program (MM2H)
by K. Jayaraman, Shin Yuin Khu, Shaian Kiumarsi
Abstract: In the modern days of advancement, people prefer to migrate from one country to another for change in lifestyle and better prospects in social, cultural, economic and environmental standards. A second home consideration deserves almost the same feeling of thoughts and importance as the primary residence. The Malaysian government is promoting Malaysia My Second Home (MM2H) program to attract more foreigners to settle down in Malaysia in order to boost the macro economy and tourism industry. The present article investigates the intention of Japanese and Indonesians towards choosing Malaysia as a second home. About 97 respondents participated in the primary survey of which 51 (52.6%) were Indonesians and 46 (47.4%) were Japanese. The respondents from both Indonesia and Japan have expressed almost similar average intention scores with moderate response to consider Malaysia as their second home. The findings of the study reveal that economic environment, social environment, political status, and retirement life were among the significant factors on the intention to consider getting a second home ownership. Surprisingly, the factors of attraction, safety and security were not found to be significant. It is understandable that only international tourists might consider destination attractiveness to be an important factor, but not second home seekers. Furthermore Malaysia is a safer country to live, compared to other ASEAN countries due to its latest sophistication and multiethnic culture.

Application of Multi Grade Fuzzy and ANFIS approaches for performance analysis of Lean Six Sigma system with sustainable considerations
by Ben Ruben R, S. Vinodh, Asokan P
Abstract: Lean Six Sigma (LSS) is a data driven world-class manufacturing strategy that aims at improving the firms competitiveness and operational performance through reduction of waste and process variation. Sustainable manufacturing aims at creation of manufactured products through economically viable processes that have minimal negative environmental impacts thus conserving natural resources and energy. In recent days, modern manufacturing firms are experiencing a paradigm shift where their core focus is to enhance their quality level with zero defects and also to improve their sustainable performance. In an aid to achieve this, manufacturing firms have started to adopt both LSS and sustainable manufacturing strategies in order to attain integrated benefits. After implementing the integrated strategies successfully, it is necessary to measure the performance of such systems to track the improvements and their sustenance. This article reports a research carried out to analyze the performance of LSS system integrated with sustainability considerations in manufacturing firms using Multi Grade Fuzzy (MGF) and Adaptive Neuro Fuzzy Inference System (ANFIS) approaches. During this research, a performance assessment model consisting of 6 first level dimensions and 30 Second level dimensions was designed to assess the performance of LSS with sustainability considerations. Data pertaining to the assessment was gathered from a manufacturing firm and computations were performed subsequently. The score based on MGF approach is found to be 6.74 and that of ANFIS approach is 6.51. Based on the output score of both the approaches, the case organization was found to possess Strong LSS performance with sustainability considerations. Based on the computed score, improvement actions were recommended and implemented subsequently for further improving the performance level. The study could facilitate improvement in LSS performance incorporated with sustainability aspects.

An optimal policy for three-tier supply chain for processing an agricultural product with a stochastic demand
by S. M. Shahidul Islam, Md. Abdul Hoque
Abstract: Processed agricultural products are very common nowadays. Control of the management cost of these products plays an important role in delivering them to customers with reasonable prices. There are a few works on controlling this management cost in the literature. However, they are limited to a two-tier supply chain (SC) consisting of a single-manufacturer and a single-retailer. This study presents an optimal policy to a three-tier SC of processing an agricultural product with a stochastic demand, consisting of a single seasonal supplier, a single manufacturer and multiple retailers. A safety stock is maintained to meet extra demand. The objective is to identify the number of shipments and the shipment sizes in a cycle to be delivered to the manufacturer and the retailers in order to minimize the chain-wide costs of ordering, setup, shipment and holding. Both the algebraic and the classical calculus methods of solution to the problem are presented. We summarize both the methods in an algorithm using parallel multiple jumps technique to obtain global optimal integral solutions to problems. They provide the same solution to each of the numerical problems studied, two of which are presented here. Managerial insight of this model is highlighted with a numerical illustration.

Maximizing Manufacturers Profit in a Dual-channel Supply Chain with Disruption Risk
by Chieh Lee, Xun Xu, Chia-Chi Hsu
Abstract: With the rapid development of the e-commerce, more customer demands are generated through online sales channels. Together with traditional sales channels through retailers, the manufacturers need to implement the dual supply chain management to enhance their performance. However, both of the online and traditional sales channels might face various sources of disruption risks under the globalization and the high complexity of the supply chain network. Using a theoretical modeling approach, three industrial cases, and sensitivity analysis, we discuss the optimal pricing strategy of manufacturer in the dual channel supply chain with disruption risks. We find that the influential factors of maximizing profits of a manufacturer include its pricing strategy, product market share, disruption risk probabilities, and product distribution proportion between the online and offline channels.

Element-Capacity Difference Algorithm for Optimal Bin Packing
by Deep Shah, Aakash A, Vimal Samsingh
Abstract: In this paper, we consider the NP -complete problem of 1-D bin packing. In the Bin Packing Problem, a set of numbers or elements that need to be loaded in the bins are considered. The total load of the elements in any bin must not exceed the bin size or bin capacity. These elements must be packed or loaded in the bins in such a way that there is minimum amount of space left in it, and also the number of bins to be used is minimized. We present a new algorithm, which helps in tackling the bin packing problem, by giving optimal solutions in minimum time. The currently used algorithms require the elements to be sorted before loading. Our algorithm works in a way that avoids the sorting operation before loading, giving the same best fit results.rn
Keywords: Keywords—Bin Packing; Sorting; Optimal Solution; Element Capacity Difference.
Multi-Objective Assembly Line Balancing Problem Under Uncertainty using Genetic Algorithm
by Ferdous Sarwar
Abstract: This paper addresses the single-model multi-objective assembly line balancing (SALBP) problem with fuzzy processing time. A fuzzy optimization model is formulated for the problem. In the classical mathematical formulation of SALBP, the relevant data are considered deterministic. But, the data of the real world problems are imprecise, vague or uncertain, and then the input data can be only estimated as within uncertainty and this uncertainty may be represented by a fuzzy number. The concept of fuzzy numbers is introduced to treat imprecise data, such as the processing time of each task. Due to the NP-hard nature of the ALB problem, heuristics are generally used to solve real life cases. In this paper, an efficient heuristic have been proposed to solve the fuzzy multi-objective ALB problem. The proposed heuristic is Genetic Algorithm (GA) based with a special chromosome structure that is efficient to handle fuzzy job time through the evolution process. As the proposed algorithm finds out the optimum solution as a trade-off among several objectives, it outperforms the existing heuristics on several test cases. The proposed algorithm can be effectively used in the design phase of an assembly line.

Electronic Word-of-Mouth in the Mobile Service Sector: The Role of Service Quality and Customer Emotional Response
by Mohammed Alsaggaf, Kevin Lu, Xiaoying Li
Abstract: It is essential for mobile service providers to deliver high quality services that could attain customers positive emotions, as this will encourage them to spread positive eWOM in several platforms about the service. However, previous telecom service studies have failed to examine the impact of service quality on eWOM intention through customers emotions. This study aimed to investigate the effects of service quality on electronic word-of-mouth (eWOM) via customer emotional responses as mediators in the mobile provider industry. We developed a research framework based on stimuli-organism-response (SOR) theory that helps to analyse the aspects of service quality affecting customer behavioural intention. This research adapted a questionnaire for quantitative data collection. A total of 582 surveys are analysed using structural equation modelling. There are three main findings; first, this study indicated that service quality tangibility and empathy are not associated with customer pleasure. We further found that there is a positive relationship between customer pleasure from service quality and intention to engage in online reviewing. Third, across genders, there is a significant difference in the relationship between service quality and eWOM intention via the mediation of emotional response. Accordingly, the research findings enhance our understanding of how to evaluate the relationship between service quality, customer emotional response, and eWOM.

Evaluation of improvement programmes in a job-shop context by simulation models
by Paolo Renna
Abstract: The continuous improvement is important to increase the companys competitiveness in today's market. The decision on the improvement programs areas is relevant to improve the enterprises performance. It is essential where to focus the investment efforts available among the different areas of the manufacturing system. In this paper, the main areas considered are: process time variability, reliability of the machines, set-up times and product defects. This paper tests the improvement programmes centralised, distributed and proposes a proportional policy by simulation models in a job shop context. The simulation experiments consider the following issues: the process time of the bottleneck, the number of bottlenecks, the degree of variation in process time, the average utilisation of the manufacturing system and the process time of the bottlenecks. The simulation results highlight how the choice of the improvement policy is not relevant when the manufacturing system has a low or high utilisation. The centralized approach leads to better results, while the proposed approach is competitive when the bottleneck may shift from one machine to another.

Linkages of QMS and Soft EMS: Perceptions of Operations Managers as Modelled by SEM
by Amjad Khalili, Md Yusof Ismail, A.N.Mustafizul Karim, Mohd Radzi Che Daud
Abstract: Empirical studies in the contemporary Operations Management (OM) literature are found to be inadequate to explore whether the ISO management standards specifically, Quality Management System (QMS) and Environmental Management System (EMS) are integrated together in the same enterprise or not. This paper aims at investigating the linkages among the QMS and Soft dimension of Environmental Management System (SEMS) and establishing their associative relationships. In this context a conceptual model is initially developed and subsequently examined in the Malaysian manufacturing industries in an empirical manner. The primary data, gathered from a sample of 329 Malaysian industries through a structured questionnaire, were analyzed using techniques from both SPSS 22 and Structural Equation Modeling (SEM). Both Principal Component Analysis (PCA) and Confirmatory Factor Analysis (CFA) were utilized from SPSS 22 and AMOS 22 respectively. Findings show that the postulated hypothesis is both statistically and practically significant. Hence, the hypothesis is supported which reflects that both the ISO standards (QMS and Soft EMS) can be integrated together in the same enterprise, and reiterates provisions for manufacturers to endure practicing these management standards to sustain their operations

by H.M. Belal, Siti Norezam Othman, Mohamad Faizal Ahmad Zaidi, Kunio Shirahada
Abstract: The significance of sustainability in present-day business is a critical issue. Companies realized that there is a critical need to sustain in global business competition and this depends upon demographic, social, and economic contexts. Many organizations, both in developed and developing economies, are trying to add customer-value solutions by adding the service concept onto their core product with the aim of gaining competitive advantage, which is known as servitization. However, there is a debate that adapting servitization in a product-based company is not always favorable for business sustainability, due to its resources and time-based requirements as well as increasing operational cost. In view of that practical issue, companies need to integrate more of the service concept into their offerings, including service solutions that can enhance social conditions and recipient aspects. Addressing social issues while transforming its well-being service solutions successfully is an arduous task as strategic collaboration and action with appropriate partners are required, of which can be extended to the local government agencies as well. This study demonstrated how collaboration advances the manufacturing-based industry to transform its business structure as a social service-oriented and well-being solution, thereby being able to sustain its business vis-

A Neural Networks Model for Green Supplier Selection
by Hansa Lysander Manohar, Ganesh Kumar Ramesh
Abstract: There have been studies on supplier selection in the past. But organizations today are also interested in evaluating their suppliers on green and sustainability criteria. With increasing awareness of green and sustainable processes and products, there is pressure on the organizations to select only green suppliers for their operations. While this is a step towards more responsible organizations, managing the suppliers of an organization becomes an important task. This clearly warrants a structured approach for evaluation of suppliers on green and sustainability criteria. This paper models the relationship between these criteria and the supplier selection. A Neural Networks model is used for analysis of the data obtained from samples in the Indian Automotive industry. MATLAB is used for analysis of the Neural Networks model. This model captures any non-linear relationship between the inputs and performs better compared to many other techniques. The output of the Neural Networks model is used for rating a supplier and hence to arrive at a decision. This model is helpful for managers as it acts as an objective assessment criterion for suppliers.

Supply Chain Management in the Services Industry: A Study from a Middle-Eastern Country
by Arthur De Souza, Abubaker Haddud
Abstract: This paper examines how operations from services providers are nowadays positioned regarding the effective management of service supply chains by assessing the existence of process for selection of strategic suppliers, model of services contract most utilized with suppliers and customers, common practices applied to the management of services demand, and how the discipline of supply chain management is currently understood by local practitioners from the services sector. The primary data was collected through the use of an online survey applied along leaders and managers from services organizations operating in the marketplace of a Middle-Eastern country.
The results revealed that the participated professionals from the services sector demonstrated a very good understanding of the concept of supply chain and how improvements can be obtained in the level of competitive advantage. Such improvements are gained by applying the best practices from SCM to the development of services level and business performance through an effective management of the demand and supply; however, the understanding of the concept of SCM is still narrow and not so clear for the majority of surveyed practitioners within the services sector. Fixed price contract remains the most utilized model of contract with customer and strategic suppliers. Although best practices for demand management were recognized by local practitioners; outsourcing and vendor management inventory practices are not yet effectively explored by local services provides.
A contribution to the academic body of knowledge in the field of Operations and Supply Chain Management has been achieved by the results from this study. This is achieved through the development of a better comprehension of how the concept of supply chain management is understood by local practitioners and to what extent some of the best practices are currently applied within operations of services organizations to the management of local product-service supply chains and an effective provision of maintenance and repair services.

Carsharing customer demand forecasting using causal, time series and neural network methods: A case study
by Anjali Awasthi
Abstract: Carsharing services are becoming popular in recent times. Deploying right number of fleet at stations is a critical component in assuring high quality service for customers. This can be done efficiently if customer demand is predictable or known in advance. In this paper, we address the problem of customer demand forecasting for improving carsharing operations. Three categories of methods namely causal (regression forecast, regression forecast with seasonality adjustments), time series (exponential smoothing, moving average) and neural networks are evaluated for forecasting customer demand. An application of the proposed methods on demand data from a carsharing organization called Communauto is provided. The results of our study show that neural network is the best method in this prediction.
The proposed work has strong practical applicability. Having an accurate forecast of the customers demands in different times of the year can help increase customer satisfaction and reach business performance targets. Especially if electric vehicles are used in carsharing companies, since they require special infrastructures.

Healthcare Relational Coordination: A Review on Parameter Selection for Modified High Performance Work Practices
by Kamatchi Thirupathi, Palaniappan PL.K.P.
Abstract: Top 25 global supply chains emphasize the role of Supply Chain Management Professionals and the Relational Coordination (RC) which known as the vital element for success. RC is essential for manufacturing and service supply chains the invisible bonding element. It involves several stages of the supply chain such as sourcing and procurement, managing operations and all logistics management activities. Importantly, it also includes coordination and collaboration with channel partners, suppliers, intermediaries, third party service providers and customers. RC captures the relational dynamics of coordinating work. RC offers a flexible and measurable network concept of teamwork based on roles and is associated with a wide range of performance outcomes and embedded in a model of organizational performance. Research findings suggest that the strength of relational coordination ties among participants in a work process depends on several parameters such as quality, efficiency, client engagement and workforce engagement. Typically, healthcare service operations deals with humans and success of technical part depends on several care parameters that result in increased quality, improved clinical outcomes, shorter length of stay, improved patient satisfaction, patient engagement, staff satisfaction and staff resilience. The open research question is how to select influencing parameters when the health care service provider uses relational coordination to achieve the above end results. To address this query, we carry out a systematic literature review using past studies during last ten years, i.e. from 2006 to 2016 to identify vital relational coordination parameters. Using relevant studies this paper clusters health care parameters and develop propositions relating parameters with the desired objectives of the health care service provider. This study is useful for health care service supply chains professional to select suitable relational coordination parameters according to their desired outcome.

Modelling the drilling crew induced process disruption factors using an ISM MICMAC approach
by Gowri Rajagopal
Abstract: Process disruption is a damaging situation in the petroleum sector as the industry involves heavy investments. In petroleum drilling operations, process disruption is inevitable mainly due to the many risks involved. The drilling crew related risk is one such potential cause of process disruption. In this paper, various drilling crew induced issues were identified through literature survey and expert discussion. The identified issues are categorised under respective Crew Induced Process Disruption Factors. These disruption factors are analyzed for their potential to disrupt the process, using Interpretive Structural Modelling framework. Based on the driving and dependent potential of individual factors, they are clustered under Autonomous, Dependent, Linkage and Independent risk factors with the help of MICMAC approach. The analysis shows that Psychological, Physiological and Cognitive risk factors have a high driving potential for process disruption, whereas Leadership, Technical prudence and Interpersonal-relation factors have low driving potential and depend on other three factors to disrupt the process. The findings of the study could give valuable insights to rig managers, supervisors and decision makers in analyzing their drilling crew and developing effective protocols and policies to enhance the crew climate and reducing Crew induced process disruption.

Case Study of SAP Implementation in a Corporation Network Plant
by David L. Olson, Zach Bochek
Abstract: Firms face the challenge of integrating systems under an enterprise resource planning (ERP) system that allows a company to analyze and utilize live data to manage product, people, and operating strategies. ERPs can leverage these resources to operate with the best cost and lowest inventory, better matching supply with demand. Many times ERPs are adopted seeking benefits without due consideration on the costs of implementation. This case highlights these implementation costs for a single plant in an international company network to provide insight into the challenges faced. Findings are that in this global organization, there was a strong tendency for upper levels to impose BPR and direction that did not always match local needs. The effectiveness of local training is evaluated, with clear need to provide more resources in terms of time for super project module leads, and more face-to-face training as opposed to global Web training from the corporation.

Strategy for enhancing ferry service in Ceuta Port
by César López-Ansorena
Abstract: This article presents a methodological framework for enhancing ferry service across the Gibraltar Strait. The study examines the opinion of users and then proposes an Action Plan for enhancing the quality of service. The actions are classified according to a priority index which is computed with the following attributes: Feasibility, Relevance, Economy, Legal Requirements and Demand. Then the actions are grouped according to their priority index into three levels. Two are the main findings of the study. From the customer point of view, the overall service level of the Port Authority is sufficient, while the overall service level of the ferry operators is still low. In regard to the second phase, only one third of the actions included in the Action Plan should be implemented in the short term. As a result, some policy recommendations for enhancing the quality of service are discussed.

Distribution of Profit in a Smart Phone Supply Chain under Isoelastic Demand
by Pradipta Patra
Abstract: This study investigates a novel supply chain (smart phone) where end consumers purchase handsets (smart phones) and service either separately (free channel) or together as a package (bundled channel). Our study considers three different power structures for the bundled channel- the handset manufacturer is the Stackelberg leader, the service operator is the Stackelberg leader and finally both the players (handset manufacturer and service provider) decide simultaneously- Vertical Nash. Previous studies have used a linear deterministic demand function to show that the supply chain player possessing superior channel power gains superior profit. We use an isoelastic deterministic demand function to point out anomalies or contradictions in already existing smart phone supply chain literature. Under isoelastic deterministic function that represents demand for smart phones we show that the supply chain player possessing superior channel power need not earn superior profits.

Identification and empirical characterization of flights’ arrival variation and its impact on departure punctuality
by Jenaro Nosedal-Sánchez, Miquel Angel Piera-Eroles, Diederik Lebbink
Abstract: In this paper, based on field data from two years of operations at a European Airport, empirical evidence of the influence of arrival variation on departure delay flight for short scheduled ground times (i.e., up to 60 minutes) is revisited, including three types of arrival situations, ‘on time’, ‘early’ and ‘late’. For early and late arrivals, variation is measured together with the extension of the Scheduled Ground Time (i.e., Actual Ground Time), and the number of departure delay minutes recorded for the next departure (i.e., average departure delay) are considered. Based on the results obtained, in this paper it is provided a quantitative method to identify the effects of early and late arrivals on airport operations, these effects impact on gate assignment scheduling and the turnaround process, its magnitude is dependent of airport’s dynamic factors such demand and capacity and its operational context. For the study case presented early arrivals are shown to generate higher airport operational disturbances compared with late arrivals that allow better reaction capacity to compensate with direct effects on turnaround time process. As a result of the empirical evidence a new challenge is open to adapt present operational airport decision support tools to avoid the impact of early arrivals by designing a buffer mechanism that can be activated in a flexible, efficient and reactive context.

A multi-objective genetic algorithm to solve a single machine scheduling problem with setup-times
by Youssef Harrath, Amine Mahjoub, Jihene Kaabi
Abstract: The objective of this research is to study the one machine scheduling problem with setup-times. Two objectives were considered; the completion time and the total weighted tardiness. Only the static version of the problem was treated. The problem is NP-hard and not approximable. We proposed a multiobjective genetic algorithm with new crossover operators to solve the problem. To validate the algorithm, we conducted an intensive experimental study, which showed that the new operators allowed the genetic algorithm to generate Pareto optimal solutions close to many developed lower bounds.
Keywords: scheduling; completion time; total weighted tardiness; genetic algorithm; multiobjective optimization
An Empirical Study of the Performance of Canadian-Owned Chains of Retail Stores
by Mohamed Dia, Pawoumodom Matthias Takouda
Abstract: The performance of a sample of public Canadian-owned chains of retail stores is assessed using Data Envelopment Analysis over the 15 years spanning the period from 2000 to 2014. Our analysis shows that the chains of food and beverage retail stores presented the best practices. In addition, we found that the impact of the 2008 financial crisis on the performance of the chains of retail stores was statistically significant only for the scale efficiencies. A similar result was found while investigating differences in efficiency between the firms that had international operations and the ones that focused only on the domestic market.

Green Supply Chain Performance Evaluation Model for Automotive Manufacturing Industries by Using Eco Balanced Scorecard
by S. Amaladhasan, Parthiban Palanisamy, R. Dhanalakshmi
Abstract: Green Supply Chain Management (GSCM) has emerged as an effective management tool and philosophy for proactive and leading manufacturing organizations. This study uses a set of initial Key Performance Indicators (KPIs) for green supply chain evaluation and believed to be appropriate for automotive companies using Eco Balanced Scorecard (EBSC). Balanced scorecard consists of four perspectives such as financial, customer, learning, and growth and internal business process, here fifth perspective as an environment is included. Drawing on the five perspectives of an EBSC, this paper first summarized the evaluation indexes synthesized from the literature relating to green supply chain performance. Furthermore, the relative weights of the chosen evaluation indexes were calculated from Fuzzy-Analytic Hierarchy Process (F-AHP). And, further, the two Multi-Criteria Decision Making (MCDM) analytical tools of Fuzzy-VIKOR and Gray Relational Analysis (GRA) were respectively adopted to rank the green supply chain performance and improve the gaps with five industries as an empirical example. Finally, a sensitivity analysis is performed to determine the influence of criteria weights and other factors in the decision-making process. The analysis results highlight the critical aspects of evaluation criteria as well as the gaps to improve green supply chain performance for achieving aspired/desired level. It shows that the proposed Fuzzy-MCDM evaluation model of green supply chain performance using the EBSC framework can be a useful and effective assessment tool.

An Efficient supplier selection Model for Hospital Pharmacy through Fuzzy AHP and Fuzzy TOPSIS
by Manivel Palanisamy, Rajesh Ranganathan
Abstract: This article investigates the significance of supplier selection in hospital pharmacy. In recent global scenario, the selection of supplier for the pharmacy is a crucial role to prompt service level as well as total value cost. Normally, high quality services, inventory and customer satisfaction is influenced mostly by the supplier selection process variable. The supplier selection normally depends on many criteria such as cost, delivery of the product, service, flexibility with the consumer, etc. The uncertainty during supplier selection could be handled by Multi-Criteria Decision Making (MCDM) techniques. A methodology is developed to analyze the qualitative and quantitative variables involved in the supplier selection process and it is illustrated with the case study of a hospital pharmacy. This paper analyze the alternatives, criteria and sub criteria of the supplier selection process by multi criteria decision making approach of Fuzzy Analytic Heuristic Process (FAHP) and Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS) methods. Based on discussion with the pharmacy manager, five criteria were chosen and analyzed. The decision makers determined the weights of the criteria and sub-criteria and evaluate the alternatives and ranks them by FAHP and FTOPSIS method. Finally compare the results obtained by FAHP and FTOPSIS methods and select the appropriate supplier which helps to improve the overall efficiency of the pharmacy.

A hyper-heuristic framework for solving the delivery problem with time windows
by Hiba Yahyaoui, Saoussen Krichen, Abdelkader Dekdouk
Abstract: We address in this paper a delivery process with time requirements in the supply chain stated as follows: orders launched from customers are centralized and assigned to firms' depots for the delivery process. The consideration of a depot and a set of customers belonging to different firms, is seen as a VRPTW that serves $n$ customers using a subset of vehicles. We implement in this paper a DSS that handles the delivering activity in the supply chain. The DSS embeds a GRASP and Genetic components for generating promising solution in a concurrently run time. In addition we proposed a $VNSH$-based hyper-heuristic that tries to select the most accurate neighborhood at each iteration to apply according to its previous performance.
Simulation results are conducted on Solomon's benchmarks. The DSS recorded very competitive results regarding state-of-the-art approaches.
