  • A Comparative Evaluation of Contemporary Models for Lean Manufacturing Practices   Order a copy of this article
    by Amjad Khalili, Md Yusof Ismail, A.N.Mustafizul Karim 
    Abstract: Lean Manufacturing (LM) is a thought developed in Toyota, thus, there is lack of studies on whether the implementation of LM is appropriate for different enterprises because of differences in organizational and social culture and labor. This paper critically analyzes Eleven (11) contemporary models for LM in an attempt to find a unified model that can be applied by enterprises. In the literature models have a tendency to focus only on few single components. However, different enterprises use diverse dimensions and models for measuring LM. It aims to review the various LM models prevailing in the contemporary research papers along with presentation of an in-depth analysis exploring the similar and dissimilar aspects. The LM models adopted by different enterprises are quite diverse as revealed through this investigation. The outcome of this study produced a matrix comprising conjoint 98 elements linked with LM 11 models. These represent soft and hard LM elements found in the literature.

  • Innovation Development in Service Firms: A Three-Model Perspective   Order a copy of this article
    by Thomas Anning-Dorson 
    Abstract: This paper develops a three-model approach through the dynamic capability view to showcase the forms and dimensionalities service innovation could take. The paper explains that the different resource and capability base for firms provide the source of variation for innovation. These capabilities allow service firms to create and implement innovation through their service mix that represents basic competitive tools for service engagement, interaction with customers and through the market as a result of external capability activation. The approach recommends the development of innovation with the service mix which is the basic competitive tool for service firms; through the customer-firm interface that enables value co-creation; and the market that allows the firm to capitalize upon its external capabilities. These service innovation dimensions therefore determine how well a service firm performs on the market in both the short and long term.

  • Towards an efficient IS service management: The internal customers Zone of Tolerance   Order a copy of this article
    by Hugo Ribeiro, Belém Barbosa 
    Abstract: This article addresses the zones of tolerance (ZOT) as a diagnosis tool for managing the quality of Information Systems (IS) service delivered to internal customers. It aims to contribute to a better understanding of internal customers ZOT by considering the frequency of use and skills in IS as explanatory factors. A survey was administered to the internal users of one companys IS department. 276 valid questionnaires were obtained, representing a response rate of 70%. The results show that internal customers have narrow Zones of Tolerance, which differ according to the users IS skills and how frequently they use the IS support service; occasional users and skilled users are the least susceptible to heterogeneity in the service delivery. This approach enables IS management to focus on users expectations, making service delivery more efficient by allocating the resources where they are most needed

  • Green Supplier Selection in Fuzzy Context: A Decision Making Scenario on Application of Fuzzy-MULTIMOORA   Order a copy of this article
    by Saurav Datta 
    Abstract: Green Supply Chain Management has become an important avenue in current business scenario. The concept of GSCM is to integrate environmental thinking into traditional supply chain management. A firms sustainability performance is greatly influenced by appropriate supplier selection in the green supply chain context. In selecting appropriate green supplier, various green criteria need to be considered along with traditional supplier selection criteria. The decision making in the context of green supplier selection becomes much more complex due to involvement of subjective selection criteria. Subjective human judgment often bears ambiguity and vagueness in the decision making; whilst fuzzy set theory overcomes the challenges of imprecise and inconsistent human judgment in ambiguous decision environment. In this context, a decision making scenario in relation to green supplier selection has been articulated in this paper aiming to investigate the applicability of MULTIMOORA in fuzzy setting (F-MULTIMOORA). The ranking order of candidate suppliers has been compared to that of fuzzy-TOPSIS. Finally, an attempt has been made to determine a unique quantitative performance index for each of the green suppliers; based on which a ranking order has also been arrived.

  • Assessment of Lean Manufacturing Practices: An Operational Perspective   Order a copy of this article
    by Masoud Rahiminezhad Galankashi, Syed Ahmad Helmi 
    Abstract: The main goal of this study was to propose a new framework to assess the operational activities of lean manufacturing (LM). Lean related activities of supply chain drivers are less investigated in previous literature. To fill this gap, the operational activities of logistic (facility, transportation and inventory) and cross-functional (information, sourcing and pricing) drivers of supply chain were proposed in this study. These activities were then ranked using an Analytical Hierarchy Process (AHP). The proposed activities were investigated by the cycle view of supply chain. Finally, the proposed framework was translated to a survey (Appendix A) to be used for assessing the leanness of manufacturing companies.

  • Extending the Range of Service Facilities   Order a copy of this article
    by Markku Tinnilä 
    Abstract: The need to understand how different types of service facilities and resources are best directed to cater for various regular and contingent service requirements has been addressed in a number of service facility classifications. These suggest what type of a channel or service constellation best matches a more or less complex activity. With the development of technology and changing social behaviour, the improved opportunities to harness social networking resources, as well as, the resources and institutions for effective service provision, need to be understood in a broader context. For this, we suggest a classification of service facilities that accounts also for the use and roles of publicly available traditional service encounters, as well as, agents, specialists and internal service resources. rnInformation is more predominant in services now than earlier and new types of services facilities are often based on open networks and provide new capabilities in services. This paper focuses on service facilities and particularly to the extension of their range by reviewing the literature of service facilities, by identifying gaps in earlier frameworks and proposing an extension in the range of service facilities for better understanding of the opportunities created by new types of facilities. Illustrative examples are provided of the new types of digital and knowledge-based service facilities. rn

  • A Framework for Evaluating the Status of Supply Chain Integration (SCI)   Order a copy of this article
    by Rajendra Sahu, Anil Kumar, Manoj Kumar Dash 
    Abstract: Supply chain management (SCM) is among the most frequently discussed topics in corporate world today. Constant efforts are being made to develop value-added processes that deliver innovative, high-quality, low-cost products on time with greater responsiveness than ever before. Supply chain integration plays an important role to achieve the same. Unfortunately the SCM concept has not been implemented in totality and there is a huge disconnect between supplier and customer. Many issues need to be addressed to integrate the supply chains of many industries. But the first step is the recognition of the present status of integration so that false notions are removed and fruitful work starts towards better integration and thus higher Supply Chain (SC) profitability. The present work tries to find out the critical parameters related to Supply Chain Integration, which if addresses properly can provide improvements in supply chain integration effectiveness. Thereafter, the study after establishing comprehensive list of information that flow through a generic SC and identifying their impact on the SC cost. Finally, a framework has been articulated to enable an organization to identify its state of supply chain integration.

  • Presenting a multi agent system for estimating risk in supply chain management   Order a copy of this article
    by Leila Ahmadpour, Abolfazl Kazemi, Soroush Avakh Darestani 
    Abstract: Nowadays, supply chains play an inevitable role in prompt handling of varying customers needs. Furthermore, with increasing emphasis on vulnerabilities in supply chains, effective mathematical tools for analyzing and understanding appropriate supply chain risk evaluation are now attracting more attention. Administration of a successful supply chain depends on how efficiently of the network design is measured and how source risks effect it. This research has two objectives. The first one is to design a multi agent supply chain network that addresses an uncertain environment threatened by different risk sources in order to capture the real world conditions; the second one is to present a methodology for estimating risk in the proposed network. Moreover tree of scenarios are constructed and risk assessment model considering domino effect is built in order to carry out the overall quantitative risk assessment.Then, probability theories are applied in the quantitative method.In conclusion, the key benefits and experience gained from this study and further research opportunity are emphasized.

  • Effect of Shape of the Demand Function and Permissible Delay in Payments on Economic Order Quantity of High Technology Products   Order a copy of this article
    by Alok Kumar, Udayan Chanda 
    Abstract: Often, sales curve of a technology product exhibit a small peak and then decline, before continuing with the traditional bell shaped curve. Under this situation sales curve of the technology products show bimodal pattern. Traditional EOQ models have ignored the bimodal pattern of demand phenomenon during development of the policy frameworks. The approach in this paper is to study the effect of bimodal demand function, on economic order quantity model. Based on hazard rate demand, an integrated EOQ model is discussed in the paper for permissible delay in payments, under the assumption that supplier may offer credit periods to the retailer. The proposed framework is demonstrated with a numerical example and a comprehensive sensitivity analysis is also performed to validate effectiveness of the model.
    Keywords: EOQ, Hazard Rate, Bimodal Demand Function, Permissible delay in payments

  • ERP implementation in public healthcare, achievable benefits and encountered criticalities An investigation from Italy   Order a copy of this article
    by Andrea Chiarini, Emidia Vagnoni, Luca Chiarini 
    Abstract: Enterprise Resource Planning has been mainly implemented in private industries and there are few inquiries of implementation in public healthcare, particularly in Europe. Hence, this paper aims to enrich the debate concerning public healthcare by investigating one of the first applications in Italy. \r\n The research aims at highlighting the benefits brought by the implementation as well as the criticalities encountered. We found that benefits can be classified into four theoretical categories: patients satisfaction, stakeholders satisfaction, operations efficiency, and strategic and performance management. Whereas criticalities such as complexity of the project, process reengineering and staffs involvement can impede the implementation. The novelty and value of the paper lie in a new classification of benefits and criticalities concerning Enterprise Resource Planning implementation in public healthcare.\r\n The classification is particularly useful for practitioners and managers who want to implement structured Enterprise Resource Planning in complex organizations such as large public hospitals. We concluded with the limitations of this research and the new avenues of research opened. \r\n

  • Sales Force Behavior and Best Practice Pricing Drive a Products Return on Investment   Order a copy of this article
    by Timothy Baker, David Collier, Vaidy Jayaraman 
    Abstract: A causal model is proposed that defines the relationships between safes force behavior and effectiveness, current pricing compared to a new way of setting pricing benchmarks, and a products return on investment (ROI). The purpose of this paper is to investigate what drives consistent pricing decisions and financial performance, and introduce a new benchmarking metric. Sales agents and pricing executives for business-to-business (B2B) manufacturers in the durable goods industry were surveyed. A total of 385 complete surveys were used in the data analysis. Sales force behavior and effectiveness is measured by a latent construct based on survey questions. A price adherence fraction (PAF) is defined that measures current pricing decisions against the best (i.e., highest logit probability out of ten pricing situations) pricing decision for that particular product-firm-market pricing situation. The structural equation model that tested if the actual survey data fit the hypothesized causal model was reasonably acceptable while a more parsimonious multiple regression model was statistically valid in all respects at predicting a products return of investment. Finally, the Malcom Baldrige National Quality Program (www.baldrige.nist.gov) has long been an advocate for benchmarking organizational performance against industry practice and competitors. The price adherence fraction methodology provides a new tool to evaluate the quality of pricing decisions by benchmarking current pricing decisions against competing pricing decisions given certain business conditions

  • Mathematical programming and grey wolf optimizer for minimizing sum of the total due date assignment, maximum tardiness and delivery costs for a supply chain scheduling problem   Order a copy of this article
    by Parisa Assarzadegan, Morteza Rasti-Barzoki, Hossein Khosroshahi 
    Abstract: This paper focuses on the integration of the three most important and practical decisions in a supply chain, including due date assignment, production scheduling and outbound distribution. The issue under consideration is to minimize the summation of maximum tardiness, and due date assignment and batch delivery costs. In to provide solution methods, first, two mathematical programming models including one mixed non-linear model and one mixed linear model to solve it are presented. After these developments, since the problem is NP-hard and solving real problems on a large scale is virtually impossible, the combinational meta-heuristic algorithm based on Grey Wolf Optimizer and heuristic algorithm for solving the problem are presented. The GWO is a fast and robust algorithm in which the number of parameters that should be controlled are few. In this study, various computational tests have also been used to evaluate the effectiveness of the development methods -Taguchi method to set the parameters, design of experiments to generate the experiments, and analysis of variance to analyze the results. The computational results show that the combinational meta-heuristic method introduced in this paper puts in a high performance.

  • A multi-objective spatial queuing model for the location problem in natural disaster response   Order a copy of this article
    by Mohammad Hossein Zavvar Sabegh, Mohammad Mohammadi, Zeynab Dashti khotbesara, Abolfazl Mirzazadeh 
    Abstract: Each year, natural disasters caused tremendous hurt to threaten infrastructure and millions of people all over the world. Hence, the natural disaster management and appropriate responses are all countries anxiety. The first option after a natural disaster is emergency response. Emergency operations are one of the most important components of the emergency response that are required in the short time after the occurrence of disaster. For this reason specified sites for the establishment of the emergency medical centers are needed. In this study, we define a new multi objective location problem for emergency therapeutic centers that include minimizing the average response time, minimizing the cost of the emergency medical centers and maximizing surface coverage demands, given the size of the budget that is acceptable to guarantee a minimum level of coverage. from the point of view of computational complexity, it is classified as an NP-hard problem, since it will require algorithms with the ability to solve problems in non deterministic polynomial (NP) time, but the solution can be verified in polynomial time, moreover, the term hard means thatit is at least as hard as the hardest problems in NP Hence, we used PASA, NSGAII, and NRGA algorithms to solve this multiple objective model. After comparing the solutions, NSGAII had a better performance. This field is still in its infancy and many useful future studies could be considered such as: creating new model based on fuzzy parameters, using innovative meta- heuristic approaches and exact solution to solve the problem.

  • Supply Chain Management in Traditional Industries in Brazil: A Relational View   Order a copy of this article
    by Fernando Viana, Milton Sousa 
    Abstract: This multiple case study investigated supply chain management (SCM) and relational competitive advantage in companies from the textile, footwear and food industries in the Northeastern region of Brazil. We used constant comparison method to analyze the data collected by in-depth interviews. Some important constructs of SCM and Relational View characterize the relationships, like absence of formal contracts, investments in specific assets, supplier base reduction, long-term relationships, information exchange and knowledge exchange. The relationships with suppliers in the footwear industry have greater alignment to SCM and contribute more significantly to the relational competitive advantage, especially through joint development of materials and products and innovation, which is very important for textile and footwear industries of which are heavily influenced by fashion and, therefore, need the ability to innovate in order to stay competitive in the market. The results permitted the development of three theoretical propositions to be tested in future studies.

  • Service Recovery Strategies Using Social Media Sites   Order a copy of this article
    by Ying Fan, Run Niu 
    Abstract: This study investigates a service organizations service recovery strategies using social media sites. Based on 347 mini-cases from the Twitter accounts of a sample of major airlines, we conducted qualitative analysis using grounded theory approach. We analyzed the relationships between the three elements of service recovery including customers motivations to complain, service failure types and agent responses. This study offers service providers practical implications to design their recovery strategies. Identification of customers motivations to complain supports the role of social media sites as a complementary service recovery channel and more importantly, as the final defense of an organizations service recovery system. The investigation on the relationship between customers motivations to complain and service failure types indicates that customers utilize social media sites no differently when different failure types occur. However, different failure types do trigger different sets of agent responses. Further, social media agents respond differently according to customers motivations to complain.

  • Contact Centre Service Excellence: A Proposed Conceptual Framework   Order a copy of this article
    by Surya Dharamdass, Yudi Fernando 
    Abstract: This paper aims to develop a proposed conceptual framework that can be used in studying the determinants of contact centre service excellence for the continuously growing contact centre business globally. A content analysis method is performed on a range of English-written published papers between 1993 and 2014 to explore the proposed determinants of contact centre service excellence. The primary observation shows that there is limited academic literature in this area. The findings from the distillation of the proposed determinants of contact centre service excellence in essence suggest that there should be a high focus on the people customer service agents (CSAs) hiring criteria, training and development, reward system, team structure and the cross-functional co-ordination process. The implication to future researchers is to focus on these determinants to better understand the impact on service excellence. For practitioners, the implication is to consider reviewing the current determinants used in their organisations to achieve service excellence and consider adopting the proposed determinants.

  • Service Gap Deployment (SGD): a framework to link quality gaps to service activities   Order a copy of this article
    by Fiorenzo Franceschini, Luca Mastrogiacomo 
    Abstract: This paper presents the Service Gap Deployment (SGD), a new method to prioritize crucial to quality activities of a service that does not completely satisfy customer expectations. In the SGD, service activities (SAs) are related to gaps between customer expectations and perceptions so as to identify SAs that may need a redesign or improvement in order to satisfy customer needs. The method, which expands the Gaps Model of Service Quality by Parasuraman et al. (1985), supports the design of evolutionary and sustaining improvements of the service parts that generate customer dissatisfaction. Specifically, the SGD introduces three major contributions: (i) it creates a map relating service dimensions to SAs; (ii) it highlights crucial to quality activities and (iii) it allows a focused improvement of the analysed service.

  • Hot strip mill production planning and sequencing   Order a copy of this article
    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.

    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   Order a copy of this article
    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   Order a copy of this article
    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.

  • Failure analysis of automobile spares in a manufacturing supply chain distribution centre using Six Sigma DMAIC framework   Order a copy of this article
    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.

    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.

  • Coordination and Pricing Decisions in a Closed-Loop Supply Chain   Order a copy of this article
    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.

  • Predicting the Behavioural Intention to adopt Lean practices: An Empirical Study in the Manufacturing Industry   Order a copy of this article
    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.

    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.

    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.

    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.

    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.

    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   Order a copy of this article
    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   Order a copy of this article
    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.

  • The bi-team orienteering problem with time window   Order a copy of this article
    by Mahdi Bashiri, Amirhossein Karimi 
    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   Order a copy of this article
    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.

  • Inter-organizational Learning in the Context of Third Party Logistics Services   Order a copy of this article
    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.

  • Quality Management System and Sustainability: A Malaysian Perspective   Order a copy of this article
    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 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   Order a copy of this article
    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.

  • Using weather data to improve demand forecasting for seasonal products   Order a copy of this article
    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.

    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   Order a copy of this article
    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.

    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.

  • Analyzing interactions of agile supply chain enablers in Indian manufacturing context   Order a copy of this article
    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   Order a copy of this article
    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.

    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.

  • New Enhanced Differential Evolution Algorithms for Solving Multi-depot Vehicle Routing Problem with Multiple Pickup and Delivery Requests   Order a copy of this article
    by Siwaporn Kunnapapdeelert, Voratas Kachitvichyanukul 
    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.

  • Performance measurement of the leagile supply chain   Order a copy of this article
    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.

  • Macro and micro logistic aspects in defining the parts-feeding policy in mixed-model assembly systems   Order a copy of this article
    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.

  • A new mathematical model for non-fixed destination multi-depot multiple traveling salesmen with time window problem   Order a copy of this article
    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.

  • Analysis of patient flows in Elective Surgery: modelling and optimization of the hospitalization process   Order a copy of this article
    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   Order a copy of this article
    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   Order a copy of this article
    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.

  • Managing Quality within Existing Supply Chains: Case studies from Jordan   Order a copy of this article
    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.

    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.

    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.

    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   Order a copy of this article
    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   Order a copy of this article
    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.

    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.

    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   Order a copy of this article
    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.

  • A Pay-What-You-Want Pricing Model for Restaurants   Order a copy of this article
    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   Order a copy of this article
    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 well-established methods shows that this new metaheuristic is competitive and represents a substantial addition to the arsenal of tools for solving the problem.
    Keywords: Uncapacitated exam scheduling; plant propagation algorithm; local search; hybridization.

  • Mergers and Acquisitions Strategic Fit in Middle Eastern Banking: An NDEA Approach   Order a copy of this article
    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.

    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.

    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.

    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.

    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   Order a copy of this article
    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   Order a copy of this article
    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.

    Abstract: This research explores the adoption of self-service technologies (SST) among customer in the postal service industry, specifically in postal service in Malaysia. A structured questionnaire was designed to elicit customer responses. Data were collected from 268 respondents but only 260 were found usable for the data analysis. The responses were analysed using the VB-SEM statistical technique using Smart-PLS software towards testing the proposed model. The research findings found that responsiveness, assurance and self-service technologies have significant relationships with customer satisfaction. In terms of mediation effect of SST, only reliability was found to have a positive relationship with customer satisfaction and SST were found to partially mediate the relationship of SERVQUAL dimensions and customer satisfaction. This study contributes to literature in the postal service industry especially in Malaysia in managing their customer satisfaction. It is evident that responsiveness drives the satisfaction of customers. The SST introduced by post office in Malaysia is useful tools for customers.

  • Element-Capacity Difference Algorithm for Optimal Bin Packing   Order a copy of this article
    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.

  • A goal programming and simulation based study for overall process improvement in an Indian hospital   Order a copy of this article
    by Bhawesh Sah, Rohit Titiyal, Sonia 
    Abstract: This study shows how the quality of service can be improved in a hospital by utilising simulation and goal programming technique without adding any significant resources. The study considers two types of patients, health check-up patients and outpatients. Multiple simulation exercises were carried out using ARENA to describe the flow of patients as well as find the delays and bottlenecks in the process. The results from ARENA show that significant process delays exist in the hospital because of which the patients have to wait long intervals for their consultation session with the doctor as well as laboratory examinations. Various key factors for process improvement have been identified such as waiting time (for both types of patients) and utilisation of various resources. Various appointment systems are considered to find the best schedule for patients with doctor, labs and clerical staff treated as key resources. The problem is formulated as a goal programming problem.
    Keywords: simulation; healthcare; scheduling; appointment systems; ARENA; goal programming.

  • Is personality a key element of Six Sigma project success?   Order a copy of this article
    by Phillip W. Witt, Timothy Baker, Nancy W. Ashley, MaryAnne Winniford 
    Abstract: Many quality improvement techniques, including Six Sigma, rely on teamwork. Little of the research on personality and teams has been incorporated into quality management theory and practice. This paper summarises the pertinent personality literature with Six Sigma research and describes the results of a multiple-case study. Two new personality variables relating to openness to new experiences and conscientiousness were found to have a potentially strong impact on project success. Also, a new variable that can be described as the overall level of creativity in the project team was determined to have significant potential. Finally, this work further confirms the critical nature of project complexity, project uncertainty, and team leadership to project success.

  • Scales for measuring mobile service quality: a literature review and identification of key dimensions   Order a copy of this article
    by Jun-Yeon Heo, Chie-Hyeon Lim, Kwang-Jae Kim 
    Abstract: Mobile service quality (m-SQ) is vital to manage the competitiveness of a company in the mobile business market. Existing studies on m-SQ share key characteristics of m-service in general, such as mobility and context awareness. A set of common m-SQ dimensions that reflects such key characteristics would serve as the theoretical backbone of m-SQ. This research aims to conduct a comprehensive review of existing studies on m-SQ scales and identify key dimensions of m-SQ to understand the essence of m-SQ scales. A total of 45 existing studies on m-SQ scales were reviewed and seven key dimensions of m-SQ scales were identified. This study is expected to serve as a solid knowledge-base for conducting new investigations on m-SQ scale development as well as help practitioners utilise m-SQ scales.

  • An innovative model to optimise inventory management: a case study in healthcare sector   Order a copy of this article
    by Antonio Forcina, Antonella Petrillo, Gianpaolo Di Bona, Fabio De Felice, Alessandro Silvestri 
    Abstract: In the age of competition, no industry can survive without pondering much about reducing expenditures wherever possible. Management of inventories represents one of the most important areas in business, trade and industry. The scheduling of production lots, as well as their sizing, is an area of increasing research attention within the wider field of production planning and scheduling. In the present paper a new mathematical model to find the target stocking level which minimises the total cost of the system while satisfying the service level constraint is presented. Starting from the analysis of inventory management models in literature, a completely original model has been developed and applied to a real case in healthcare sector. The analysis of the results, arising from the case study, allowed to evaluate the effectiveness of the proposed models and to highlight the differences. Nevertheless the proposed model has characteristics of generality that allow the application in other areas.
    Keywords: inventory management; lot sizing; healthcare sector; supply chain; dynamic models.

  • Green Supply Chain Performance Evaluation Model for Automotive Manufacturing Industries by Using Eco Balanced Scorecard   Order a copy of this article
    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 Empirical Study of the Performance of Canadian-Owned Chains of Retail Stores   Order a copy of this article
    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.
