Design of cellular manufacturing system for power press industry to reduce total traveling time by hybrid algorithm
by Manoharan Shunmugasundaram, V. Anbumalar, P. Anand, P. Sivakumar, S. Nagarajan
Abstract: Part family identification and Machine Cell formation are the two major steps in Cellular Manufacturing System. Cell formation is a complex process and there are several approaches for this purpose viz., Array based clustering, Agglomerative clustering, Mathematical programming, Graph partitioning, and Non traditional methods. The problem with first two approaches is that the quality of the solution is dependent of the initial part machine incidence matrix. A new algorithm for cell formation combining the techniques of array based clustering and agglomerative clustering is proposed. The above Proposed method is tested by using standard problems and compared with other method results for the same standard problems. Grouping efficiency is the most widely used measures of quality for Cellular Manufacturing Systems. The proposed algorithm is used to form manufacturing cells in a power press industry to increase productivity by reducing total travelling time.

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

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

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

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

Supply Chain Management in the Services Industry: A Study from a Middle-Eastern Country
by Arthur De Souza, Abubaker Haddud
Abstract: This paper examines how operations from services providers are nowadays positioned regarding the effective management of service supply chains by assessing the existence of process for selection of strategic suppliers, model of services contract most utilized with suppliers and customers, common practices applied to the management of services demand, and how the discipline of supply chain management is currently understood by local practitioners from the services sector. The primary data was collected through the use of an online survey applied along leaders and managers from services organizations operating in the marketplace of a Middle-Eastern country.
The results revealed that the participated professionals from the services sector demonstrated a very good understanding of the concept of supply chain and how improvements can be obtained in the level of competitive advantage. Such improvements are gained by applying the best practices from SCM to the development of services level and business performance through an effective management of the demand and supply; however, the understanding of the concept of SCM is still narrow and not so clear for the majority of surveyed practitioners within the services sector. Fixed price contract remains the most utilized model of contract with customer and strategic suppliers. Although best practices for demand management were recognized by local practitioners; outsourcing and vendor management inventory practices are not yet effectively explored by local services provides.
A contribution to the academic body of knowledge in the field of Operations and Supply Chain Management has been achieved by the results from this study. This is achieved through the development of a better comprehension of how the concept of supply chain management is understood by local practitioners and to what extent some of the best practices are currently applied within operations of services organizations to the management of local product-service supply chains and an effective provision of maintenance and repair services.
Keywords: Supply chain management; product-service supply chain; services providers; practices; models; Middle East.
Carsharing customer demand forecasting using causal, time series and neural network methods: A case study
by Anjali Awasthi
Abstract: Carsharing services are becoming popular in recent times. Deploying right number of fleet at stations is a critical component in assuring high quality service for customers. This can be done efficiently if customer demand is predictable or known in advance. In this paper, we address the problem of customer demand forecasting for improving carsharing operations. Three categories of methods namely causal (regression forecast, regression forecast with seasonality adjustments), time series (exponential smoothing, moving average) and neural networks are evaluated for forecasting customer demand. An application of the proposed methods on demand data from a carsharing organization called Communauto is provided. The results of our study show that neural network is the best method in this prediction.
The proposed work has strong practical applicability. Having an accurate forecast of the customers demands in different times of the year can help increase customer satisfaction and reach business performance targets. Especially if electric vehicles are used in carsharing companies, since they require special infrastructures.

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

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

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

Technological changes have revolutionized the entire business model. E-Commerce is one such technological change which has revolutionized the economy. This has been facilitated through e-banking. With benefits such as hassle-free, quick and real-time banking, internet banking still lacks far behind the number of online users in India. To ensure greater participation in online banking, banks need to understand the customers perception towards e-service quality. Customers perceive these services in the form of several quality attributes. By identifying factors critical to e-banking services, banks can appropriately devise focused programs. The study attempts to examine the determinants of e-banking service quality and their impact on customer satisfaction. The study used primary data based on a convenient sampling of two private sector banks in Delhi region to produce a 5-factor structure relevant in the Indian context. The exploratory factor analysis produces dimensions of efficiency, trust, fulfillment, responsiveness and systems critical to e-service quality satisfaction. The regression results show trust and privacy as the most critical factor influencing e-banking service quality perceptions. Further, the study provides theoretical and managerial recommendations for increasing online banking adoption and improving overall customer satisfaction. Limitations and future scope of research are further discussed.

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

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

Feedback mode preference and performance improvement with a handheld scanning device
by Elizabeth Copeland, Reuben Burch, Lesley Strawderman, Kari Babski-Reeves, Linkan Bian, Katherine King
Abstract: This study was conducted to determine if combining feedback modes is beneficial for operator performance on a handheld scanning device within the services distribution industry. An industrial handheld scanner was used to examine four feedback conditions: 1) auditory, 2) auditory-visual, 3) auditory-tactile, and 4) auditory-visual-tactile. Participants completed one trial under each experimental feedback condition during one experimental session. In each trial, participants scanned 50 boxes during a simulated box scanning task. Task completion time, completion time ranks, hit rate and false alarms were recorded and analyzed. While the auditory-visual-tactile feedback combination produced the fastest task completion time, there was no significant improvement in operator performance between the four feedback settings tested. Through further understanding of the most preferred feedback modes, or combination of such, identification of improved scanner settings for this device and task can be made.

Modeling Patient Satisfaction in Healthcare
by Sanjeev Bordoloi
Abstract: Patient satisfaction is often a top priority within healthcare organizations. This satisfaction is measured through patient surveys and understanding patients perceptions of the services they are offered. Increasingly, patient satisfaction has been regarded as a major factor in measuring overall service quality of a healthcare firm. One area that hospitals have found challenging is their service offered over the phone. It is therefore important to observe the call centre operations within a healthcare organization to fully understand what leads to patient dissatisfaction, and thereby recommend ideas to improve patient satisfaction. The present study analyses a hospital that is facing challenges related to their phone services. The goal is to improve the overall service quality, ultimately leading to improvement in patient satisfaction. Quality tools such as Pareto Analysis and Fishbone Diagrams were used to conduct the analysis. Then, quantitative models from waiting line management were used to determine optimal staffing levels of call centre agents and triage nurses to meet quality goals as stipulated by the management, in terms of acceptable customer waiting time.
Keywords: Patient Satisfaction; Pareto Analysis; Fishbone Diagram; Nurse Staffing.

Analytical evaluation of relation between alignment and performance in service triads Three differing contexts
by Mohan Gopalakrishnan, Srimathy Mohan
Abstract: Supply chain (SC) agility depends on organizational structure; customer satisfaction, and collaboration among SC actors. To understand these dimensions and their impact on supply chain performance, we have analyzed three triadic relationships. Examples in this research paper involve (a) hospital buyers managing high-cost supplies with outside vendors, but influenced by its physicians; (b) specialized hospital outpatient units that need to coordinate patient flow with medical staff and attending physicians; and (c) logistics service providers with assets managing its demand with external customer through an internal brokerage service. Specifically, we have analytically evaluated organizational- pressures (hierarchical versus bureaucratic), practices (scheduling, time-blocks), and structures (captive versus autonomous) and how they influence alignment between interactions in the respective triads to ultimately affect performance, namely, lower supply expenses; balancing customer satisfaction and asset utilization; and profitability.

Gender and Worker Productivity Issues Associated with Sport Betting From an Ethical Perspective
by Amber A. Smith-Ditizio, Leslie Graham, David Nichols, Kerry Webb
Abstract: There are ethical perspectives that may be useful in examining the worker productivity dilemmas associated with sport-related office pooling activities, both face-to-face and online, especially from gender viewpoints. Using selected intrinsic and extrinsic motivational factors grounded in Consequentialism, Deontology, and Virtue perspectives, an empirical study was conducted on highly educated knowledge workers in the Pittsburgh, PA area. Many male respondents felt that engaging in sport-related betting within the workplace was more acceptable than their females and tended to feel more utilitarian in their approach to justify such actions. Typically a Deontology-based ethical perspective suited males as they felt that sport-related gambling activities had a more positive impact on the emotional state of the office atmosphere and were more willing to become personally less productive and use company resources at work during sporting events.

by Cláudio Benevenuto De Campos Lima, Rodrigo Nunes Ferreira, Danilo Garbazza Vieira, José Francisco Tebaldi De Castro, Gilson Brito Alves Lima, Julio Cesar De Faria Alvim Wasserman
Abstract: In recent years, oil companies have implemented collaborative decision-making centers for well construction (drilling centers), where several solutions are used in real time with significant impact on company operations. These applications provide necessary data for better decision-making; lowering costs by optimizing rig activity time, besides reducing travel and logistics costs. The purpose of this study is to determine perceived value and quality from a specific real-time data transmission solution. A quantitative method was applied through an online survey to test the evaluation model of the data transmission solution of an oil operator in Brazil. It was found that the main factor responsible for dissatisfaction is related to technical support. This approach can be used for other solutions and services and showed as being scalable to different scenarios in the oil industry.

Sourcing Analytics for Evaluating and Selecting Suppliers Using DEA and AHP: A Case of the Aerospace Company
by Seong-Jong Joo, Bradley Boehmke, Hokey Min, Ozden Bayazit
Abstract: Sourcing represents one of the most upstream supply chain activities which often dictates the rest of downstream supply chain activities. As such, a poor sourcing decision has a significant trickle-down effect on the effectiveness of a buying firms manufacturing and logistics decisions. Considering such significance, it is imperative for the firm to make a wise, systematic decision in evaluating and selecting suppliers. To support a critical sourcing decision, we propose a supplier evaluation decision-aid tool within the framework of business analytics which takes into account the multiple facets of supplier performance evaluation criteria. As a core of such a tool, we develop a relatively new model which is capable of considering both objective and subjective performance criteria simultaneously using a combination of data envelopment analysis (DEA) and analytic hierarchy process (AHP). To verify the practicality and validity of the proposed analytics-based tool, we applied it to an actual problem facing a U.S. aerospace company.

Towards A New Model of Work Passion
by Waed Ensour, Dia Zeglat, Hadeel Al-Maaitah
Abstract: This study aimed to investigate how work passion is conceptualized in a new setting and culture as well as to identify factors influencing work passion from the viewpoint of Arab workers. The study investigated the case of Jordanian hotel workers by conducting two focus groups with 16 participants, followed by 25 in-depth interviews. The findings indicate that passion is defined as an intense and positive feeling of the presence of `enjoyment` in doing a particular job, which illustrates an emotional aspect. Passion depends on the presence of psychological (personal attachment), and situational (extrinsic) aspects. Passionate workers are assumed to show enthusiasm, commitment, and loyalty, representing the behavioural aspect of passion. Furthermore, passion is conceived as an advanced state but not detached from job involvement, engagement, and organizational commitment, meaning these can be engendered by the effect of passion. Although the Jordanian hotel employees were found to be not very different in terms of their conceptualizing of work passion, this study presents new factors that are assumed to affect passion. Finally, contrary to what is proposed in the literature, passion was perceived only as a positive state and distinct from workaholism.

Inventory model optimization for a closed-loop retailer-manufacturer-supplier system with imperfect production, reworks and quality dependent return rate
by Anindya Rachma Dwicahyani, Eva Kholisoh, Cucuk Nur Rosyidi, Pringgo Widyo Laksono, Wakhid Ahmad Jauhari
Abstract: This study investigates a closed-loop supply chain (CLSC) inventory model consisting of a retailer, a manufacturer and a supplier. Here, the return rate is considered to be a variable which depends upon the acceptance quality level of the returned items. The manufacturer performs manufacturing and remanufacturing processes to satisfy the retailers demand. The manufacturing process is assumed to be imperfect and produces some defective items. All defective items are then reworked via reworking process. Two recovery processes are considered in the model, which are remanufacturing and refurbishing. The recoverable items which cannot be perfectly recovered will be categorized as refurbishable items and then sold to the secondary market at a reduced price. A solution methodology is provided to find the optimal solutions of the model. A numerical example and sensitivity analysis are performed to show the application of the model and to understand the effects of the changes in key parameters on the models behavior, respectively.
Keywords: remanufacturing; closed-loop supply chain; recovery; inventory; inventory model; refurbishing; imperfect production.
Hidden structure and value network: Shedding light on position assessment
by Elina Karttunen, Mika Immonen, Mikko Pynnönen, Jouni Koivuniemi
Abstract: This study focuses on hierarchical structures of value networks of service systems. But how can the central and influential network positions be found in the value network? The position of actors is extracted using the hidden structure method (HSM) and centrality metrics of social network analysis (SNA). Both analyses apply adjacency matrix data that reveal direct dependencies of actors in a value network. We measured indegree, outdegree, betweenness, and closeness centralities to each actor to compare SNA and HSM results. HSM can reveal the actors who conduct the most significant activities, as well as more peripheral actors who have a strong influence on core actors. Thus, HSM does not neglect the hierarchy between actors. Our methodological contribution suggests that in parallel with widely used SNA centrality measures, researchers should leverage HSM to define influential actors. Two pharmacy concepts in Finland provide the empirical research context.

Implementing Lean Paradigm in an Indian Foundry Facility: A Case Study
by Sanjiv Kumar Tiwari, Ritesh Kumar Singh, Sharad Chandra Srivastava
Abstract: This article seeks to establish the effectiveness of lean manufacturing in eliminating the hidden wastes, maintaining better inventory control and reducing the total production time. A large Indian foundry facility is utilized to illustrate the adopted approach. Firstly, current state mapping is prepared to have the knowledge of the existing procedure followed in the production of castings. In addition, relevant data such as, cycle time, changeover time, percentage of defects, percentage downtime and inventory in between the processes are collected for each process. Further, the future state map is created, after amending the entire process, by adopting the methodology proposed by Rother and Shook (1999). Additionally, the required buffer size (number of Kanbans) at each stage and the sequence of production are also estimated by adopting the method advocated by the Lean Enterprise Institute (2004). Finally, improvement is accounted in terms of reduced lead time of the process.
Keywords: Lean manufacturing; value stream mapping (VSM); Kanban; supermarket; pull system.
Behavioral operations management identification of its research program
by Jure Erjavec, Peter Trkman
Abstract: The rise in popularity of the behavioral operations management field has resulted in several attempts to clearly establish this multidisciplinary field. Given the divergent views of what the field actually includes, this paper attempts to contribute to an ongoing debate about the current state of the field as a research field and its future development. The paper uses Lakatos view that suggests that instead of individual theories, scientific progress should be viewed in the context of research programs, which consist of the hard core and the protective belt. To identify subfields, the paper combines the literature review with a co-citation network analysis of the behavioral operations management field between 1957 and 2015. Six clusters are identified. The Domain base cluster represents the hard core of the field, while five other clusters (Newsvendor, Bullwhip and inventory optimization, Social goals, Supplier relationship, and Organizational behavior) represent its protective belt. In addition to the exploration of existing clusters, the analysis in the paper offers an excellent starting point to identify and position further research questions. A study like this is easily replicable and enables following the evolution of the field.

Optimizing emergency medical centers location with a response-time-decreasing approach using hybrid methods of optimization and simulation
by Ahmad Kamali, Seyed Mojtaba Sajadi, Fariborz Jolai
Abstract: Decision making about the emergency medical centers location is a complicated problem which managers of health care systems are confronted to. In order to respond to requests as fast as possible, the emergency medical centers should be planed in the best condition. There are some cases that affect on emergency medical service operation, like calls distribution, traffic condition and operative costs. The paper combines the optimization techniques with simulation in locating the emergency medical centers in order to decrease the operative costs and also increase the quality of medical emergency services. The method first, locates the centers using optimization techniques, and then having assigned the ambulances to the centers, it analyzes different scenarios of locating the centers and assigning the ambulances to them in a dynamic method using computer simulation. The proposed method of emergency centers location and ambulance-assignments was implemented in Isfahan (Iran) as a case study and resulted in lower response time. The comparison of results with real situations shows the efficiency of this method.

Game theoretical approach to price a product under two-echelon supply chain containing e-tail selling channel
by Hamed Jafari, Seyed Reza Hejazi, Morteza Rasti-Barzoki
Abstract: In this study, pricing decisions are investigated on a dual-channel supply chain including one manufacturer and multiple retailers. The manufacturer sells a product through the Internet and through the retail channel, simultaneously. It is assumed that the market is controlled by the manufacturer. Thus, the manufacturer becomes leader and the retailers perform as followers. In this setting, the Bertrand and Collusion game-theoretic models are developed to analyze the pricing strategies among the retailers. Then, the equilibrium decisions are compared and some managerial insights are presented. It is found that the manufacturers profit and the profit of the whole system given by the Bertrand game are higher than by the Collusion, while this inference is reversed for the retailers profits. Moreover, larger the number of the retailers in the retail channel leads to lower retailers profits, whereas the manufacturers profit and the profit of the whole system increase.

Service Operations In Public Sector Agencies: Evidence From NCDMV
by James B. Martin, Joyendu Bhadury, Kwasi Amoako-Gyampah, Steve Bert, Eugene Murray
Abstract: This paper studies customer service in public agencies within the context of vehicle titling and registration services in North Carolina Division of Motor Vehicles (NCDMV). Over 17,000 observations were recorded from the operations of 27 offices in North Carolina and analysis performed on the same to delineate operational factors that impact service quality. Primary findings include: salient determinants of customer service and waiting times; benefits of process standardization/automation; evidence that privately-operated offices with permanent contracts or those that are state owned and operated provide worse service than those operated by private contractors with time-limited contracts and; evidence that incomplete transactions represent a significant customer service problem. The study also provides evidence of the consistency of NCDMVs compensation rates, a surprising result given that these rates were not set by the legislature after adequate data-based analyses. Theoretical implications of the findings are discussed along with the legislative impact of this study.

Abstract: Abstract: Plethora of research have indicated that, teamwork and team control have become typical and important part of task performance in construction project delivery. Thus ensuring optimum task performance in construction project delivery is perceived to be influenced by the level of project team effectiveness and team control. However, little is known about the influence of the dynamics of team control on the effectiveness of construction project teams in task and project team performance. The aim of this study was to explore the effects of the dynamics (modes) of team control on the level of team effectiveness in construction project delivery. Through a deductive research approach, a partial least square structural equation modelling (PLS-SEM) was used on data collected through questionnaire survey conducted in South Africa. The results revealed that Formal Control (FC) and Informal Control (IC) account for about 65% (0.648) and 30% (0.304) respectively of the total 71.0% variance in the level of team effectiveness in project delivery. This suggests that formal control in project teams makes substantial effects to the level of team effectiveness in project delivery whereas in the case of informal control, it effects could be interpreted as being moderate at the 0.05 significance level. From these findings, it can be considered extremely significant for project teams to enhance and legitimize their formal and informal controls in project delivery towards improving the effectiveness of the team in task and team performance.

Service Facilities and Hotel Performance: Empirical Evidence from Hotel-Level Data in Thailand
by Jordi Meya Domínguez, Piriya Pholphirul
Abstract: The main purpose of this paper is to examine the effects of service facilities on performance within the hotel industry. Its unique contribution is the use of national-representative secondary data on the hospitality industry in Thailand, as a case of a major tourist destination country. Covering 2,627 hotel observations, our estimated regression indicates that service facilities affect native (Thai) guests and foreign (non-Thai) guests differently, which can lead to different strategic actions for each group. Among all kinds of service facilities, providing Internet service seems to be the greatest contribution to hotel performance. Therefore, in terms of managerial implications, hotel managers should make providing a sound Internet connection a priority in order to ensure the successful short-term and long-term performance and development of their business. As for social implications, especially among small and medium-sized hotels, improving hotel performance by upgrading service facilities is another important tool in promoting tourism as a poverty reduction strategy.

A Study on the Impact of Backorder Sales on an Integrated Supply Chain
by Ratna Kumar K, Radha Ramanan, Sridharan R
Abstract: The integrated procurement, production and distribution planning (IPPDP) problem consists of multiple suppliers who supply raw materials to multiple plants to produce a single product to meet the demand in multiple time horizons. The present research focuses on the analysis of the effect of backorders on the IPPDP problem in a three-echelon supply chain that consists of suppliers, manufacturers and retailers. The IPPDP problem is formulated as a mixed integer linear programming (MILP) model and the optimal solution is obtained with the solver LINGO. The total net profit obtained for the scenario involving lost sales is compared with that for the scenario which involves lost sales and backordering. For a set of problem instances, an increase of 10.29% in the average total net profit and 4.80% in the average fill rate is obtained for the lost sales and backordering scenario compared to the lost-sales-only scenario.
Keywords: Integrated procurement; production and distribution; backordering; lost sales.

An Integrated Mathematical Programming Model for a Dynamic Cellular Manufacturing System with Limited Resources
by Seyed Taghi Akhavan Niaki, Esmaeil Mehdizadeh, Mansour Shamoradifar
Abstract: This paper proposes an integrated integer nonlinear programming model for a concurrent cell formation and production planning problem in a dynamic cell-manufacturing system (DCMS) with limited resources to setup cells and to procure machines. The proposed model seeks to minimise the total costs associated with the production planning and the cell construction and formation under a dynamic system. To validate the model, it is first converted to a linear programming. Then, a numerical example is presented based on which the branch and bound method is used to solve it employing the Lingo 8 software. Besides, due to NP-hardness of the problem, two meta-heuristic algorithms namely a GA and a PSO are utilised to solve large-scale problems. In addition, the Taguchi method is used to calibrate the parameters of the meta-heuristics in order to find better quality solutions. Computational results confirm the efficiency and the effectiveness of the proposed solution algorithms.

The management of customer requirements in a Product-Service System (PSS) context: a case study in the medical equipment sector.
by Nicolas Haber, Mario Fargnoli
Abstract: The paper addresses the evaluation of customer requirements in the implementation of services in a Product-Service System (PSS) context. The extension of services has expanded considerably, yet their correct combination with products is still problematic to manufacturers. Services are characterized by ambiguities and vagueness, hindering their effective implementation. Conventional product design tools such as Quality Function Deployment (QFD) are limited when comprehending the intangibility of services and hence evaluating and prioritizing customer requirements. To address this topic, QFD is adapted to a service context through the integration of the fuzzy logic and the Analytic Hierarchy Process (AHP) as a means of reducing inaccuracies. The approach is applied to a case study in the medical field and its results are compared to the traditional QFD to analyse its outcomes and the effectiveness of the augmentations in increasing the usefulness of QFD in a PSS context.
Keywords: Service requirements; product-service systems; customer requirement prioritization; quality function deployment; analytic hierarchy process; fuzzy logic.
Restoration of Managers Work Identity in Service Departments: the Role of Service Operations Design
by Ayham Jaaron
Abstract: Strategies used for regulating and improving service departments managers (SDMs) valued identity at work through viable and sustainable models of operation are relatively missing. This is particularly true when one considers the paucity of previous studies that have explored the linkages of service operations designs and the construct of SDMs work identity. This paper, using the lens of identity theory, explores the impact of creating an appropriate service operations design, using systems thinking principles, on the restoration of SDMs work identity and behaviour. Using multiple-case study approach in three organisations service Departments in the UK, the results demonstrate that the systems thinking for service operations design is an enabler for promoting dramatic changes to the role of SDMs in the workplace. These dramatic changes are resembled by the creation of a transformational management style, changing the role of SDMs from employees monitors to supporters, and adoption of new discursive practices that are embracing more people-cantered perspective. While the paper introduces an interesting theorization of managers identity with systems thinking methodology, it also contributes, for the first time, a discussion of managers identity theory to the service system design literature in a highly-demanding business environment.

Kaizen costing as a culturally-based tool: a Portuguese case-study.
by Amelia Ferreira-da-Silva, José Pereira, José Vale, Vera Morais, Carla Magalhães
Abstract: In the 1970s and 1980s, Japanese success was explained by its culture, and entrepreneurs from the West realised that productivity is not reducible to rationalism and technology. Indeed, nowadays it is well recognised that what best distinguishes an organisation from its competitors are not physical and tangible characteristics. Intangible dimensions, like organisational culture, play an important role in organisational success or failure. This research argues that organisational culture interacts with kaizen costing so that effective implementation of kaizen requires a special organisational cultural puzzle. A qualitative approach was adopted. The case study method was used to understand how kaizen costing interacts with organisational culture. The findings suggest that effective implementation of kaizen costing requires a high level of culture coherence. Further research is necessary before we can consistently generalise our conclusion. However, our findings bring new insights to the role of low-level workers in effective implementation of strategic options like kaizen and highlight the importance of intangible assets like organisational culture. This article draws attention to the tenuous frontier between kaizen costing and lean production, and it puts organisational culture on the centre.
Keywords: Japanese Management Accounting; Kaizen Costing; Organizational Culture; Organizational Change; Qualitative Research.

Stochastic modelling and analysis of maximum entropy of MX/G/1 queueing system with balking, startup, and vacation interruption
by Nithya R P, Haridass M
Abstract: In this paper, a batch arrival single server queueing system with startup, balking, and vacation interruption is considered. The customers arrive in bulk according to poisson process and the server provides service one by one to the primary arriving customers. During the busy period of the server, the customers may join the queue with probability α or may balk from the system with probability 1-α. On completion of service, the server goes for vacation when there are no customers available in the queue, otherwise, it resumes service. After a vacation, the server stays idle until the customer arrives and when an arrival occurs, the server begins the startup work and resumes service. Furthermore, vacation is interrupted suddenly when a customer arrives during vacation and goes for startup and then starts service after completing the startup work. For the above model, the probability generating function of the steady state system size distribution at an arbitrary time epoch is obtained by using supplementary variable technique. Various performance measures and busy period distribution are derived. Cost model is also developed. Some particular cases are discussed to justify the result obtained. Moreover, maximum entropy principle is employed to determine the solution for steady state probability distribution of system size and expected waiting time in the system. The results are compared with the analytical results of the proposed model and validated through numerical illustration.
Keywords: Bulk arrival; single server; vacation interruption; balking; startup; maximum entropy principle.
Ant Lion Optimization (ALO) algorithm for two stage supply chain network associated with fixed charges
by Parthasarathy Manimaran, MARIAPPAN KADARKARAINADAR MARICHELVAM
Abstract: In this paper an effective Ant Lion Optimization (ALO) algorithm is proposed for two stage supply chain network associated with fixed charge transportation problem (FCTP) to provide optimal or near optimal solutions. Generally in a FCTP, fixed cost is incurred for every route, along with the variable cost that is proportional to the amount shipped. In some circumstances, the variable cost is associated with quadratic variables in which the cost function will be non-linear. This problem is one of the NP-hard type combinatorial optimization problems and hence the computational time to obtain an exact solution increases in a polynomial fashion. Moreover, the exact solution techniques cannot be used when the size of the problem increases. Also, the FCTP is more difficult to solve due to the presence of the fixed costs that result in discontinuities in the objective function and renders it unsolvable by the direct application of the transportation algorithms. The aim of this paper is to determine the least cost transportation plan that minimizes the total variable and fixed costs while satisfying the supply and demand requirements of each plant and customer. This paper aims to show the application of ALO approach for solving FCTP. The performance of the proposed ALO is compared in terms of total cost with other algorithms addressed in the literature such as Genetic Algorithm, Simulated Annealing and Ant Colony Optimization. The computational results reveal that the proposed ALO provides better solutions.
Keywords: ALO; Fixed cost; NP-hard; Transportation Problem.

A Lagrangian-Relaxation based Bounding Approach for the Convoy Movement Problem in Military Logistics
by S.A. Ezhil, Rajendran Chandrasekaran
Abstract: Convoy movement problem (CMP) is an important optimisation problem, especially occurring in military logistics, which focuses on routing convoys concurrently in a network. The CMP is subject to constraints for preventing certain interactions between convoys such that the objectives related to travel times of them are minimised. We propose a Lagrangian relaxation (LR) approach to efficiently obtain a lower bound on the optimal solution. Our LR approach does not have integrality property, and hence the lower bound obtained is always tigher than the lower bound obtained using the LP relaxation. As CMP is an NP-complete problem, lower bounds are useful to evaluate the solutions obtained by a heuristic. From our computational experimentation, it is found that the proposed LR approach is superior to the existing LR approach.

Accuracy in measuring customer satisfaction
by Peter Madzik, Miroslav Hrnciar
Abstract: The study reports an analysis of the accuracy of three selected methods point direct scoring (PDS), ranking (RK) and multi-choice (MCh) in processing the results of large-scale surveys. The reference value for assessing their accuracy was the degree of overall satisfaction. We adopted a structured approach: First a reference value was selected against which to assess accuracy. The next step was determination of the methods for calculating the comparison value. After the calculation was made, the values calculated using each method were compared to the reference value and the resulting data were used to determine the accuracy of the given method. The RK method had a statistically significant advantage over the PDS and MCh methods in the accuracy of its relationship to the reference value. It was calculated that the RK method was on average 7.8% more accurate than the PDS and MCh methods.
Keywords: Overall satisfaction; satisfaction index; attribute importance.
An Examination of the Operating Efficiency of Wholesale and Retail Firms
by Xun Xu, Yinfei Chen, Wenhui Liu
Abstract: This study investigates whether a firm's competitive advantage, measured by its relative operating efficiency, can be maintained in the long run. Based on a sample of US listing firms in the wholesale and the retail industries from 1995 to 2015, we examine the dynamics of the trend and stability of firms' operating efficiency in the long run. We find that companies that are moving ahead in the short run cannot guarantee their operating efficiency status in the long run. In the long run, operating efficiency can trend upwards, downwards, fluctuate, or remain flat. The findings are consistent to both industries, except that in the retail industry, there are more firms that consistently fall behind than firms that are in other categories of efficiency. This study provides implications for firms to measure and improve their operating efficiency dynamically over the short and long horizons to win the competitive market.
Keywords: Dynamics of operating efficiency; wholesale firms; retail firms.
An integrated approach for solving cell formation and intra cell machine layout problem considering operation sequence and alternative process routing.
by RAJA Shanmuganantham
Abstract: Cellular manufacturing is a group technology approach wherein parts and machines are arranged in flow production. Most of the cell formation methods in the previous literature have addressed the zero-one matrix for solving cell formation problem with single process routing. Even though multiple routings are considered in some cases, machine layout is not considered which results in increased number of backward flow, voids and exceptional elements. In this research, we have proposed a new heuristic approach for solving cell formation problem based on new similarity coefficient method and identifying intra-cell machine layout based on flow matrix by considering operation sequence and alternative routings. In order to validate the efficiency of our proposed method, five well-known test problems from the literature are employed and the results are compared with the existing method the results clearly show that the proposed approach which that provides superior or equal solution than the existing method.

Green manufacturing in garment industry through the application of fundamental lean tools
by N.SENTHIL PRABHU, Rajenthira Kumar D, S.R. Devadasan, Gnanaguru R.
Abstract: In this paper, a model named as green through lean tools (GTLT) is proposed. GTLT was designed to implement green manufacturing in four phases through the adoption of three fundamental lean tools namely 5S, A3 Report and kaizen in garment manufacturing companies. The novelty of GTLT model is that the degree of implementing green manufacturing paradigm in the garment manufacturing company is assessed by using colours. Green colour refers to mean that green manufacturing paradigm has been fully implemented in the garment manufacturing company. After designing GTLT model, its practicality was examined in nine garment manufacturing companies. The results of this examination indicated that GTLT is an economical, powerful and practically feasible model that would enable the garment manufacturing companies to implement green manufacturing paradigm through the application of the above mentioned three fundamental lean tools.
Keywords: Green manufacturing; lean manufacturing; garment manufacturing; 5S; A3 report; kaizen.
ECONOMIC ORDERING MODEL FOR MULTIPLE ITEMS WITH STOCHASTIC DEMAND AND BUDGET CONSTRAINT
by Mahadev Ota, S. Srinivasan, NANDAKUMAR C. D
Abstract: The classical newsboy problem considers the single product case to determine the optimal ordering quantity which maximises the expected profit. This paper attempts to develop a newsboy type model with multiple products and stochastic demand and determine the optimal ordering quantity based on the different time periods which maximise the expected profit subject to the budget constraints. In the modern market, each individual customer has his own freedom to choose the product independently. Accordingly, this paper assumes that the demand for each product is invariably independent and follows the lognormal distribution with different mean and variance. An effective method has been developed to determine the optimal ordering quantity for each product at different time period with different level of budget constraint. From the illustrations, it is quite clear that an optimal solution can be obtained for the proposed model. The analytical structure used in the proposed model shows that the multi-product extension of the newsboy problem with budget constraint and stochastic demand is a very challenging area of research.
Keywords: optimal ordering quantity; multiple items; budget constraint; stochastic demand.
A Pareto-based optimization algorithm for a multi-objective integrated production-distribution planning problem of a multi-echelon supply chain network design
by Seyed Taghi Akhavan Niaki, Alireza Alinezhad, Abolfazl Kazemi, Keyvan Sarrafha
Abstract: This paper addresses a multi-periodic supply chain network design (SCND) problem involving suppliers, manufacturers, distribution centres (DCs), and customer zones (CZs). Logistic decisions made in each time period have a tactical nature. Location/strategic decisions are made at the beginning of the time horizon and remain unchanged until the last period. While both backorders and lost sales are considered, the aim is to design the supply chain network (SCN) under three minimisation objectives including total costs, the transfer time of products to CZs, and backorder level and lost sale of products. A multi-objective mixed-integer linear programming (MILP) model is developed and a meta-heuristic algorithm named multi-objective vibration damping optimisation (MOVDO) with tuned parameters is proposed to find non-dominated solutions. The performance of this method is compared with two popular existing algorithms called NSGA-II and NRGA when they solve some randomly generated problems.

A Heuristic and GRASP Algorithm for Three dimensional Multiple Bin-Size Bin Packing Problem based on the needs of a spare-part company
by Ali Shoja Sangchooli, S. Mehdi Sajadifar
Abstract: The three-dimensional multiple bin-size bin packing problem (3D-MBSBPP) has many practical applications in the logistic problems such as warehouse management, transportation planning and container loading. An efficient solution to the problem can have significant effects on reducing the transportation costs, improving the status and increasing the productivity and profitability of the companies. The mathematical models proposed for this problem are few in number and can, therefore, be expanded and improved much further. In this paper, based on the needs of a spare-part company in Iran, we developed a mathematical model for 3D-MBSBPP. This model takes into account the rotation of the boxes and the maximum weight constraint of the bins and then, we used a new heuristic and a GRASP algorithm for solving the model. The obtained answers in comparison with the exact method, confirm the speed and efficiency of the proposed algorithms, especially in solving the large-scale and real-sized problems.

Measuring Social Sustainable Practices in Middle Eastern Airlines: The Employees Perspective
by Ajmal Mian, Matloub Hussain, Rawdha Eissa Alsuwaidi
Abstract: Measuring social sustainability across any organisation is a complex phenomenon involving many criteria and sub-criteria. To address this level of complexity, a multi criteria decision-making process called the analytical hierarchy process (AHP) has been used in this research. Data have been collected from 15 experts of two full service carriers (FSCs) from the Middle East. The findings of this research showed that ten main criteria and 32 sub-criteria are important measures of social sustainability from the employees perspective. It has been found that employees well-being, learning, development and engagement are the most important criteria for infusing social sustainability into the airline industry. However, community and organisational culture have the lowest priority weights. Measuring social sustainability from the employees perspective is a multifaceted issue. The proposed framework can help policy makers to enhance the social sustainability standards of their employees and to gain a sustainable advantage.

An Empirical Bivariate study on Work Life Balance of Women Labors with special reference to Tannery Industry
by Vasumathi Arumugam, Prithi Arun, Kameswara Rao P
Abstract: In the present competitive scenario, any industry is focusing work life balance of their employees, to create a healthy win-win environment for both the employees and organisation. The literatures studies display that male employees or workers are affected by work life imbalance but females are more prone to work family imbalance issues. The work life balance issues are not only dependent on womens capability and energy but also dependent on various factors related to work environment (like working conditions, work flexibility, work demands, working hours, travelling time, advancement of technology, etc.) and family related factors (like family demands, support from family members, demographic profile, time, energy and other personal factors). When these family and work related factors tend to interfere with each other by making individual to concentrate on one role leaving the other an imbalance occurs between family and work, that results in work family conflict, family work conflict, stress, tension, poor performance, absenteeism and turnover from workplace. This article discusses the work life balance of women workers working within the tannery industry in Tamil Nadu, India. The researcher found that the less experienced labourers have fewer work life balance issues when compared to highly experienced labourers.
Keywords: Work life balance; working conditions; work family conflict; family work conflict and issues.

Top-down knowledge hiding in buying and supplying firms: causes, and some suggestions
by ATIF BUTT
Abstract: Knowledge management has gained vital importance in supply chain management discipline in the last few years. Many studies in supply chain management now argue that effective knowledge sharing is crucial for firms success. In addition, effective knowledge management in supply chains positively impacts a firms ability to innovate and remain competitive in the market. However, firms should remain cautions as senior managers can also deliberately hide knowledge from their subordinates in an organisation, which can negatively impact their work performance and innovative work behaviour. Therefore, the purpose of this paper is to propose some potential determinants of top-down knowledge hiding in buying and supplying firms, which can adversely affect innovative work behaviour of managers. Furthermore, some suggestions are offered to firms on how to promote the culture of knowledge sharing, while at the same time discouraging the culture of knowledge hiding in firms.

A novel multi-objective mathematical model for designing strategy map with goal programming approach
by Meghdad Haji Mohamad Ali Jahromi
Abstract: The advantage of the balances scorecard (BSC) is that considers financial and non-financial aspects simultaneously so that each of them has corresponding indicators and each indicator supported with one or more initiative(s). Selecting identified objectives in light of the importance by considering organisational constraints (i.e., resources) are important, as well as determining cause and effect relationships between them in different aspects. The purpose of this paper is to select strategic objectives from identified potential strategic objectives and selecting the important relationships between them. This paper presents a goal programming approach to model building strategy map. This model contains three goals, these goals related to relative importance of strategic objectives (G1), number of casual relationships (G2) and relative importance of relationships (G3). Finally, by solving a problem as a real case of a business company with different targets and different weight for objectives, the performance of the developed model has been examined. Results represent the models efficiency in presenting a suitable strategy map according to the decision makers want and organisational constraints.

Bi-objective optimization of the joint replenishment problem in a two-echelon supply chain
by Leopoldo Eduardo Cardenas-Barron, Pejman Ahmadi, Seyed Hamid Reza Pasandideh, Seyed Taghi Akhavan Niaki
Abstract: In this research, a bi-objective optimisation model for the joint replenishment problem (JRP) of a supply chain comprised of a single supplier and multiple retailers is developed, in which the retailers are assumed to be members of a unique distribution company. The mathematical model minimises the suppliers as well as the retailers cost subject to some constraints. The constraints are the required storage spaces for any retailer, for any product, and for all the products. The benefit of using the JRP policy is shown based on minimising total cost of supplier and retailers. Since the developed model of the problem is NP-hard, the multi-objective meta-heuristic optimisation algorithm of non-dominated sorting genetic algorithm-II (NSGA-II) is proposed to solve the problem. Besides, since no benchmark is available in the literature to verify and validate the results obtained, a non-dominated ranking genetic algorithm (NRGA) is suggested to solve the problem as well. For further validation, the Pareto fronts are compared to lower and upper bounds obtained using a genetic algorithm employed to solve two single-objective problems separately.
Keywords: Supply chain management; joint replenishment problem; NSGA-II; NRGA.
System Dynamics Modelling for Chemical Supply Chain- A Case Study
by Sunith Hebbar, Azeen Khan
Abstract: Chemical supply chain constitutes all the activities from sourcing of raw materials to the delivery of goods to customers within, or across national boundaries. The study was conducted in ABC Ltd. company which manufactures chemicals like methanol and benzene. The firm was concerned about significant risks in SC like uncertain demands and orders. Thus, a system dynamics model was developed and simulated for the SC under changing demand levels, raw material shipment time, and cycle time. The results revealed that the increase in shipment time did not affect the sales, but, the RM inventory increased. Thus, it was advised to change the ordering pattern which minimises RM inventory. The results also revealed the existence of the bullwhip effect and identified an ideal cycle time which stabilises the system. An optimum requirement of transportation resources, labour and trucks, were determined. Furthermore, appropriate suggestions were made which may help in improving the SC performance.

Development of an adapted framework for lean product development
by Naga Vamsi Krishna Jasti, Srinivas Kota
Abstract: Lean product development (LPD) plays a major role in success of the organisations product. Many researchers have proposed various LPD frameworks to implement LPD principles in the organisations without reviewing the existing LPD frameworks. Hence, this study performed a critical review of 35 frameworks with respect to novelty, background, and verification methodology used in the frameworks to identify the inconsistencies and standardise the elements. Several inconsistencies present in the existing LPD frameworks were identified and the importance of coherent theory building as well as development of coherent set of elements in the LPD was elucidated. To overcome these inconsistencies, a comprehensive conceptual LPD framework with high coherent elements was proposed.

Consumers preferences in purchasing recycled/refurbished products: An empirical investigation
by Jafar Heydari, Hediyeh Mahmoodi
Abstract: In this paper, we empirically examine consumers' behaviour in purchasing products made of recycled material. Impact of three factors of discount, warranty, and money-back guarantee (return acceptance) on respondents' willingness to buy recycled/refurbished products are analysed by conducting a survey using questionnaire on 150 respondents. Our survey examines how people with different levels of consumer environmental awareness (CEA) and perceived consumer effectiveness (PCE) behave while they buy various types of recycled/refurbished goods. To this aim, we categorise products into four sorts: 1) technology; 2) household; 3) personal; 4) luxury. Our findings reveal that recycled/refurbished technology products are more popular while there is a little interest in buying refurbished personal products. In addition, the results demonstrate that, although offering discount and warranty have a positive impact on the consumers' willingness to purchase recycled/refurbished products, more than half of the respondents prefer money-back guarantee when buying a recycled/refurbished product.

A Deterministic Inventory Model of Aluminium Refreshment Cans in Reverse supply Chain
by Ajay Behera, Sasmita Mohapatra, Rabindra Mahapatra, Harish Das, Malay Pradhan
Abstract: The purpose of this paper is to present an original model for the production-recycling-reuse of aluminium refreshment cans. It is assumed that 250 ml aluminium cans are collected from the market. The cans are then sorted into non-tainted and tainted categories. The non-tainted aluminium cans are either reproduced or utilised as re-machining blended with primary (virgin) aluminium metal for creation of new cans to fulfil demand. The tainted cans are either sent to vendor utilising poor quality aluminium or discarded in a scrap yard. Numerical studies are used to illustrate the behaviour of the model, with an emphasis on exploring the reduction of total inventory cost of system and the amount of cans going into a scrap yard. Numerical analysis conducted on the model found that the amount of cans collected had the largest influence on the outcome of the total system unit time cost.

Responsiveness model of textile supply chain
by P. Raghuram, Saleeshya P.G
Abstract: Responsiveness of the supply chain is a crucial factor in improving the capacity to earn greater profits for individual companies and the supply chain as a whole. The ability to meet customer demands promptly and improving the frequency of financial turnover are the direct consequence of responsiveness of their supply chains. This paper aims to examine the effect of the combination of material flow, information flow, lead time and overall capability on the responsiveness of a textile supply chain. With an online-cum-direct survey of 246 textile industries in South India, followed by exploratory factor analysis, we develop a model of supply chain responsiveness. Then, the developed model is validated through structural equation modelling (SEM) using model fit metrics. A comprehensive model considering the entire supply chain may lead to an improved responsiveness, greater financial turnover and allows suitable measures across the supply chain to become more responsive to the customer.
Keywords: supply chain responsiveness; textile industry; exploratory factor analysis; structural equation modelling; SEM.
Key factors of service quality of B-2-B technology providers
by Fredric Swierczek, Theerawut Monta
Abstract: Empirical studies of B-2-B service quality in B-2-B are rare, particularly in banking and telecom. This paper analyses the key factors of service quality of a technology provider for banking and telecommunications. It considers how service quality relates to the decision criteria of IT executives in these sectors for the selection of a technology provider in an emerging market. 597 IT executives in banks and telecom companies in Thailand were surveyed. Data analysis was conducted using structural equation modelling. The value of an adapted SERVQUAL/SERVPERF in B-2-B is confirmed by the bank and telecom executives. Importance based on the SERVQUAL/SERVPERF dimensions was strongly related. Expectations including customer responsiveness were second in importance. Influence of the provider was related to the decision. Executives indicated that service quality was not enough to make the decision to award a service contract. Technology providers should enhance their service quality capability and collaboration.

Facility Layout Problem By Integration of AHP and computer simulation with DEA
by Saeedeh Ketabi, Mahsa Ghandehari, Mehdi Poormostafa Khoshkrodi
Abstract: The facility layout problem (FLP) is concerned with finding the optimal facility arrangement in the existing layout. A layout generation and its evaluation are often challenging and time consuming due to their inherent multiple objectives in nature and their data collection process. This paper aims to propose an integrated approach of fuzzy analytic hierarchy process (AHP), computer simulation and data envelopment analysis (DEA) for facility layout design improvement and optimization. Computer simulation is used to determine quantitative measures. AHP is used to determine first, the weight of qualitative measures for layout alternatives and second, their qualitative measures. DEA is performed by employing total cost and wait time as the input variables, accessibility and flexibility as the output variables to evaluate different layouts. Then, the alternative layouts are ranked by solving the super-efficiency DEA model for the layouts. The results imply that the proposed methodology is more reliable compared to the existing approaches.

Optimal Inventory Management System for Deteriorating Items with Linear Demand, Shortages and Partial Backlogging in a Triangular Fuzzy Setup
by Rakesh Kumar Bajaj, Saurabh Srivastava
Abstract: In the present communication, we have proposed an optimal inventory management system for deteriorating items with linear demand, shortages, variable rate of deterioration and partial backlogging in the fuzzy environment. In real life situations, we certainly face the uncertainty component associated with the different parameters such as demand, raw materials supply, various other inventory costs, rate of deterioration, etc. Uncertainty theory in fuzzy terms has been found to be a useful methodology to describe the inherent subjective indeterminacy. The objective of the present work is to optimise the total average cost function by taking triangular fuzzy numbers into account. The defuzzification methods viz. graded mean, signed distance and centroid have been applied to obtain the results of the proposed model. For a detailed illustration of the proposed model, an example of inventory model has been considered and solved in view of the parameters involved. Further, the sensitivity analysis with respect to the various influencing parameters have been presented with the help of some graphical representations. The paper is finally concluded with a scope for the possible future work.

The path to digital transformation: overcoming prejudice in the digital era with service operations
by João Reis, Nuno Melão
Abstract: Innovation in service science and the adoption of new information and communication technologies are transforming the business landscape. While senior customers are facing ever-greater challenges to adapt to new technologies, non-aligned customers may be taking defensive stances towards the adoption of new technologies. These sceptical positions may eventually weaken the firms' strategies towards the path to digital transformation. This paper uses a qualitative case study research to analyse a Portuguese network of firms who gathered around a common technology to deliver services to their customers. Although this business network appears to be gathering nation-wide enthusiasts and seem to be a success in delivering heterogeneous services through new technologies, some customers appear to contest. The results indicate that while senior customers are trying to adapt to new technologies or at least adopting an optimistic stance by showing some kind of curiosity, a niche of sideliner customers are not overcoming preconceived misconceptions, preventing them from taking a closer contact to new markets and services. By investing on the integration of sceptical customers and service operations standardisation, firms may avoid negative word-of-mouth, find new sources of revenue and expand their business, thereby increasing their competitiveness over their rivals.

Abstract: Small and medium enterprises (SMEs) operate in complex supply and logistics systems. Most of the optimisation issues in such logistics arrangements are focused on minimising cost and time. But with rising environmental concerns, sustainable and green solutions have become important criteria along with other optimisation issues. This paper aimed to provide a solution for greening the supply chain by minimising the vehicular pollutant emission through prioritising the use of better environmental standard vehicles. The paper proposed a pollution optimisation model to reduce the pollutant emission and a cost optimisation model to minimise the transportation cost in the logistics of SMEs. The work also compared minimised cost logistics and cost of the minimised pollution logistics for analysing the difference of cost in greening the supply chain. Solution methodology used Timsort-based algorithm implemented by C++ to solve the model, and the problem is analysed over a test case for model estimation.

A case of fifty-five years of Servitization in the Frozen Concentrated Orange Juice industry
by João Batista De Camargo Junior, Silvio Roberto Ignacio Pires, Pedro Domingos Antoniolli
Abstract: Although the term servitisation was coined in the late 1980s, this paper identifies and investigates a case that has been practiced in Brazil since 1963 by a capital goods manufacturer, which is focused on supplying machines and services to largest producers of frozen concentrated orange juice in country. Therefore, the aim of this paper is to describe and analyse the main characteristics of this case. Methodology used corresponds to an exploratory and in-depth case study conducted from supplier company perspective, but also by investigating its main customer company (dual approach). Data obtained were described and analysed using a framework designed for this purpose that is based on three classic publications on the subject. Results demonstrate a case of extreme servitisation, even for standards considered in present literature.

A quantitative exploration of service brand avoidance and its antecedents
by Pierre Mostert, Danie J. Petzer, Sotira Petrou, Adele Berndt
Abstract: With consumers increasingly avoiding service brands due to a wide range of transgressions by organisations, it is surprising that research relating to service brand avoidance is lacking, with most studies focusing on positive brand associations. However, more recently researchers started exploring service brand avoidance by gaining insights into this phenomenon through qualitative research by identifying possible reasons as to why consumers would not only avoid service brands, but also terminate their relationships with brands. This paper furthers our understanding of service brand avoidance by being one of the first research studies to quantitatively explore the antecedents of service brand avoidance. Data were collected by means of convenience sampling from 299 South African cell phone users. Findings indicate that of those antecedents of service brand avoidance identified through previous qualitative studies, identity avoidance, moral avoidance, deficit-value avoidance and experiential avoidance predict service brand avoidance, whereas advertising avoidance does not.
Keywords: Service brand avoidance; identity avoidance; moral avoidance; deficit-value avoidance; experiential avoidance; advertising avoidance.
Analysis of the Factors That Influence Adoption of Information from Managerial Responses to Negative Electronic word-of-mouth
by Fayiz Shrafat, Dia Zeglat, Waed Ensour, Nael Sarhan
Abstract: The purpose of this study was to identify the informational determinants of persuasive managerial responses to negative e-WOM, when recipients accept managerial response information, and which factors encourage adoption. Using the elaboration likelihood model and the theory of information adoption, the study develops a research model to investigate information adoption determinants that influence managerial responses to negative e-WOM through informational usefulness in the context of consumer-to-business communication. The partial least squares technique is used to test the proposed model on 318 effective data points. The results show that argument quality and source credibility positively influence the adoption of managerial response information through informational usefulness. Among the precursors of information usefulness, quality factors (comprehensiveness and accuracy) exert a significant influence. Theoretical and managerial implications are discussed.
Keywords: Electronic word-of-mouth; Managerial response; Argument quality; Source credibility; Informational usefulness; Information adoption.
Design of Lean Manufacturing based strategies to improve the Production Process of a metalworking company.
by Dionicio Neira Rodado, Vanessa Judith Valle Mercado, Dayana Daniela Benitez Acosta, Juan Carlos Cabarcas Reyes, Aurora Piñeres Castillo, Guilherme Luz Tortorella
Abstract: The objective of this research is to design strategies based on lean manufacturing principles in order to improve the efficiency of the production process of a metalworking company. Lean manufacturing is a continuous improvement philosophy that aims to eliminate or reduce through different tools, all types of waste found in a production process. During the project, a detailed analysis of the production processes was carried out; with operations diagrams, Pareto charts, Ishikawa diagrams, VSM, among others. With this, it was possible to determine the different problems present in anchor rods and clamps production line. According to the project progress, each of the improvement strategies was developed, proving its functionality and utility for productivity and cost reduction. Finally, the waste reductions generated by each strategy were calculated, and then the benefits and the investment required for the implementation of the strategies, justified by the cost-benefit analysis.
Keywords: Lean Manufacturing; Waste; Productivity; VSM; SIPOC.
Big Data Project Management by Agile Approach: in the Case of the Seoul Metropolitan City Owl Bus
by Kyung Hoon Yang, Sung Hyun Kim, Chang Ik Song
Abstract: Big data has proven to be a good source in analysing complicated situations and designing complex systems. With big data analysis, solutions have become more accurate. However, due to a lack of experience with big data, projects that generally handle big data have a higher failure rate in terms of time, money and user satisfaction. Therefore, projects involving big data should differ from a typical project. Using the case of the Seoul Metropolitan City Owl Bus, the authors have setup project procedures and raised several issues developers would do well to consider when dealing with big data. When the Seoul City Government in South Korea planned the night bus lines and its schedules, it made use of big data to do so. We expect that this case analysis will guide the further usage of big data in the service sector project management.

Sustainable product development of tablet device using Environmental Conscious QFD-Weighted Decision Matrix evaluation: A case study
by S. Vinodh, Manjunatheshwara K. J
Abstract: The study applies an integrated framework of environmentally conscious quality function deployment (ECQFD) with weighted decision matrix (WDM) for sustainable development of the tablet device. ECQFD phase I prioritised design metrics were found to be 'product design', 'process improvement' and 'reduced energy consumption' with relative weights of '0.1081', '0.1014' and '0.0916' respectively. In phase II, 'battery' and 'front and back covers' were found to be prioritised components. From phase III option I, 'product design' was found to have more improvement effect and from option II 'process improvement' was found to have the highest improvement effect. From phase IV, option II was found to be the best. Three designs were conceptualised based on the results of ECQFD. Design 1 with a score of 2.63 was identified as the best design using WDM. This study could be beneficial in overcoming the lack of knowledge and realise the potential for successful sustainability implementation through ECQFD.

Developing dimensions of the marketing-operations alignment construct
by Kedwadee Sombultawee, Sakun Boonitt
Abstract: This paper develops a theoretical dimensional model of marketingoperations alignment that can be used to align strategic, tactical, and operational priorities within the organisation. Results are derived from case studies at four firms in different industries in Thailand. Data was collected using in-depth interviews with marketing and operations managers and top leadership and analysed using template analysis. The analysis found five dimensions of marketing-operations alignment, including leadership strategy, information exchange, decision coordination, performance evaluation, and reward systems. These findings supported the development of a dimensional process model of marketing-operations alignment, beginning the development of an integrative theory of marketing-operations alignment. The study provides a template for implementation in the organisation and identifies opportunities for further research. The findings imply that marketing-operations alignment should be a concern for managers, although the research is limited in that the model is not yet fully developed.
Keywords: marketing-operations alignment; market orientation; coordination decision; reward system; information exchange; leadership strategy; performance evaluation; template analysis; multiple case studies.
