  •   Free full-text access Open AccessLean Practices and the Adoption of Digital Technologies in Production
    ( Free Full-text Access ) CC-BY-NC-ND
    by Robin Von Haartman, Lars Bengtsson, Camilla Niss 
    Abstract: The use of Lean principles has long enabled the improvement of efficiency and competitiveness in manufacturing firms, but during the last decade, advanced digital and automated solutions have been more in the spotlight. It has been suggested by some authors that Lean and digitalisation are mutually exclusive, although most authors now agree that the two are indeed compatible. It thus seems that the most urgent question is not whether Lean and digital technologies can be combined, but rather how. This paper uses a large-scale survey of manufacturing units in Europe to explore the relationship between three types of Lean production practices and the use of digital technologies in production. The analysis shows that three types of Lean practices Lean flow, Lean work organisation and Lean human resource management are strongly associated with firms adoption of digital technologies in production by manufacturing firms. Based on the results it is suggested that, as a theoretical explanation, a firms experience of Lean may act as an absorptive capacity when adopting digital technologies. A number of practical explanations are also provided, e.g., that systematic improvement efforts are also beneficial when implementing digital technologies.
    Keywords: Digitalisation; Lean practices; manufacturing strategy; absorptive capacity; Industry 4.0.

  • Operational Capabilities Dissemination for Sustainable Competitiveness: Towards an Integrated Framework   Order a copy of this article
    by Cristiane Biazzin, Ely Paiva, Julio C.B. Figueiredo 
    Abstract: This article aims to present an integrated framework, composed by micro and meso factors that impact the process of operational capabilities dissemination among an intraorganisational network (manufacturing or service provider). There are various perspectives to explain it, however, due to high number of factors and complexity of operational capabilities elements, previous studies seem to be incomplete to unfold the entire process of capability dissemination. This study comprises a multi-stage empirical analysis of manager’s perceptions of the factors for building a cognitive causal model for operational capability dissemination within a network. The contribution of this study includes: 1) as a methodological tool, it can support future researchers during the difficult process of forming causal relations; 2) as a theoretical framework for operational capabilities dissemination to sustain and spread competitiveness among units; 3) can support managers to address actions for capability dissemination and overcome the challenges to keep sustainable competitiveness.
    Keywords: cognitive causal mapping; operational capabilities; organizational networks; capability dissemination.

  • A capability perspective on service provision in project-based organisations   Order a copy of this article
    by Saad Zighan, Ziad Al-Kalha, David Bamford, Iain Reid 
    Abstract: The theoretical underpinnings related to the required capabilities of service provision remain under development. Hence, this study aims to explore the pathway for service business development in project-based organisations. Using a qualitative case study approach, 30 interviews were conducted with project-based organisations from five different industries in eight countries. Thematic analysis techniques were used to analyse the data. Upon which, this study identifies the essential capabilities for the successful implementation of servitisation strategies; these direct the projects to be customer orientated and sustain the core operations of service provision. Adopting dynamic capability theory, the study offers a roadmap for how project-based organisations develop and gain these capabilities. The results indicate a difference between the companies in developed as opposed to developing countries, when building their capabilities. The study contributes to the body of knowledge and proposes to decision makers the use of effective processes to help align project operations and service provision activities. It explains how project-based organisations reconfigure their resources to build essential capabilities to provide services. Moreover, the study highlights the differences between developed and developing countries in terms of the capabilities used and how they develop them.

  • An efficient supplier selection model for pump industry through Best - Worst Method.   Order a copy of this article
    by Vishnu Raghunathan, Rajesh Ranganathan, Manivel Palanisamy 
    Abstract: Global trend has turned out customers to seek for diverse range of application-based products conferring to their prerequisites. This paper emphasis the supplier selection process in pump manufacturing industry by adopting zero inventory concept. Major factors such as cost of delivery, capacities, quality, price, stand-alone suppliers, reliability and suppliers profile etc. are the fundamental parameters in the supplier selection process which tends to have a major influence on product delivery and complete satisfaction of the customer. Multi-criteria decision-making (MCDM) technique and best-worst method (BWM) is utilised to avoid ambiguity in supplier selection and improve the on-time receipt (OTR). A novel methodology was developed to analyses supplier selection process and the developed methodology has been validated through a case study.

  • A novel multi-objective mathematical model for designing strategy map with goal programming approach   Order a copy of this article
    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 model’s 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   Order a copy of this article
    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 supplier’s 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.

  • System Dynamics Modelling for Chemical Supply Chain- A Case Study   Order a copy of this article
    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.

  • Consumers preferences in purchasing recycled/refurbished products: An empirical investigation   Order a copy of this article
    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.

  • The home care districting problem: an application to Family Clinics   Order a copy of this article
    by Olavo Diogo, Eduardo R. De Vargas, Peter Wanke, Henrique Correa 
    Abstract: There are five major issues associated with the provision of home healthcare services: facility location, districting, assignment, scheduling, and routing problems. This article investigates methods to solve home healthcare districting problems in order to improve the management of family clinic operations. Family clinic is a community healthcare centre which comprises a network of clinics staffed by a group of general practitioners and nurses providing primary healthcare services in a certain area of Brazil. The most relevant authors on this subject and the techniques most utilised to solve the districting issue are identified through a social network analysis of the authors. Finally, one of these techniques is applied to analyse its suitability for the (real) case in question, and paths are suggested to resolve territory alignment problems in the implementation of family health strategies.

  • A Deterministic Inventory Model of Aluminium Refreshment Cans in Reverse supply Chain   Order a copy of this article
    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   Order a copy of this article
    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.

  • Key factors of service quality of B-2-B technology providers   Order a copy of this article
    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.

    by Silvio Pires, Luis Eugenio Carretero Díaz, Pablo Estevez, Alba Abreu 
    Abstract: This article addresses the supply chain management (SCM) of hotels in Spain investigating whether there is a relationship between their SCM practices and their economic and non-economic results. A grouping technique, from the context of artificial intelligence (AI) known as self-organising neural networks was used and the analysis comprised hotel companies operating in Spain classified as four-star. This category includes the largest number of companies who use SCM practices. One hundred and forty-six hotels were investigated and five adjacent groups (clusters) were identified in relation to using SCM practices. Results show mainly that a broader approach when applying SCM practices in supply chains leads to better results.

  • Facility Layout Problem By Integration of AHP and computer simulation with DEA   Order a copy of this article
    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   Order a copy of this article
    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   Order a copy of this article
    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.

  • A mathematical model for pollution and cost optimized logistics based on environmental vehicle standards for SMEs   Order a copy of this article
    by Anand Jaiswal, Cherian Samuel, G. Abhishek Ganesh 
    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   Order a copy of this article
    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   Order a copy of this article
    by Pierre Mostert, .Sotira Petrou, Danie J. Petzer, 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.

  • Analysis of the Factors That Influence Adoption of Information from Managerial Responses to Negative Electronic word-of-mouth   Order a copy of this article
    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.

  • Big Data Project Management by Agile Approach: in the Case of the Seoul Metropolitan City Owl Bus   Order a copy of this article
    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   Order a copy of this article
    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   Order a copy of this article
    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.

  • A Two-Step Dynamic Scheduling and Assignment Method for the Tooling Original Design Manufacturers   Order a copy of this article
    by Chieh Lee, Xun Xu, Yaning Yang, Ming-Feng Yang 
    Abstract: Tooling original design manufacturers have to meet highly customised product design requirements and provide a reliable delivery time for their buyers. For such mass customised tooling, high uncertainties and complexity are inevitable in the manufacturing process, especially in the labour-intensive final assembly department. We propose a two-step dynamic method that helps the tooling manufacturer in scheduling and assigning jobs at its assembling department. First, the algorithm creates a queue for incoming orders based on the bottleneck sector with a modified critical ratio (mCR). Second, the orders are assigned to assembling teams by the Hungarian method based on the availability and competitive advantage of each team. This method allows managers to update each operations team on-site, reduce the statistical dependency, and avoid work-in-process inventory build-up in the production system. In a numerical study, we illustrate the effectiveness and cost reduction potential of our method.

  • The Complementarity of Lean Manufacturing Practices with Importance-Performance Analysis: How Does It Leverage Inventory Performance?   Order a copy of this article
    by Gusman Nawanir, Yudi Fernando, Lim Kong Teong 
    Abstract: This paper aims to examine the effect of lean manufacturing (LM) implementation on inventory minimisation (IM) directly and indirectly [i.e., through manufacturing flexibility (MF) as a mediating variable]. This empirical study used a survey-based quantitative data through a cross-sectional research design and stratified random sampling technique for sample selection. A total of 236 large manufacturing companies were participated in the study. Four hypotheses were tested statistically by applying structural equation modelling (SEM) with Smart PLS 3.2.7. The finding revealed that in order to leverage MF and subsequently augment the inventory performance, LM should be applied in a holistic manner because of the complementary relationships among its practices. The importance-performance map analysis (IPMA) found the LM as the main driver of IM. Despite performing at the comparable level, LM has substantially higher importance than MF. Consequently, performance should be prioritised at the implementation of LM by focusing on the most important constructs of LM (i.e., TPM, quality control, quick setup and flexible resources). This study contributes to filling the existing gaps of limited studies investigating the effect of LM on both MF and IM. The practitioners will be benefited by understanding the vital constructs of LM to improve MF and inventory performance.

    by Sami Abdullah Kadhim, M.D. Fauzi Bin Ahmad 
    Abstract: Total quality management (TQM) plays a vital role to ensure the success in educational institutions. Modern techniques should be applied in preparatory schools of Iraq in order to follow the rapid global pace. However, many previous studies have examined the impact of TQM on education (Edu.) but for the studies on Iraqi preparatory schools are limited. TQM has various approaches this study focus on cultural change, continuous improvement, and customer satisfaction. This is an empirical study; a questionnaire was adopted and distributed among Iraqi schools. Data were collected and analyses through structural equation modelling through smart PLS. It has been found that TQM has positive effects on educational performance. All three dimensions of TQM (change culture, continuous improvement and customer satisfaction) have a positive and significant relationship with educational performance. Lastly, leadership excellence is contributing more than knowledge excellence in educational performance. Meanwhile, this study will help the management of the school to strategic decision-making.

  • A two-period lot of sizing and pricing model for a perishable/seasonal item   Order a copy of this article
    by P.L. Abad 
    Abstract: In this study, we develop a two-period model for determining the lot size, period-one price and the rule for setting period-two price. The proposed model is applicable to lot sizing and pricing of a perishable or seasonal good when demand for the good is uncertain. In case of a perishable good, the retailer is assumed to follow a fixed replenishment interval which is assumed to be shorter than the fixed lifespan of the product. The interval in turn is divided into two periods. We represent demand in each period using an additive error demand function where expected demand is a decreasing function of the selling price. Consumers prefer fresh products and a farther 'best before' date, i.e., when a good is perishable, there tends to be value drop as units age over the periods. In case of a seasonal good, the planning horizon is the entire season, and there may or may not be value drop over the two periods.
    Keywords: service level; stochastic optimization; inventory management; lot sizing; pricing; two-stage; retailing; value drop; seasonal good.

  • Relationship between service quality, consumer values, satisfaction and loyalty: An empirical study of a shopping mall   Order a copy of this article
    by Domingos Fernandes Campos, Kelson W. S. Barros, Lieda A. Souza, Julio Cesar Ferro De Guimarães 
    Abstract: The primary purpose of this research is to examine the impact of mall service quality and utilitarian and hedonic consumption values on customers satisfaction and loyalty. A preliminary hypothetical model was analysed with the structural equation technique following the partial least squares approach. The results show the positive direct effect of the service quality offered by the shopping centre on customer satisfaction and consumer royalty. Utilitarian and hedonic values play an essential role in shopping centre customers satisfaction. Both shopping values help to produce satisfaction in shopping mall buyers. Hedonic values, though less effectively, also influence consumer loyalty directly. Mall managers and entrepreneurs should redouble their attention to the most important attributes associated with the quality and attractiveness of shopping malls and invest to achieve a high level of loyalty and consumer retention.

  • Working Capital Models: A Generic Framework   Order a copy of this article
    by Lotta Lind, Timo Kärri, Veli Matti Virolainen, Sari Monto 
    Abstract: The importance of working capital management has been recognised recently in academia as well as in business. Yet, research on working capital models has been scarce, and many companies focus on managing the individual components of working capital instead of a holistic approach. This paper studies working capital models comprising the management of inventories, accounts receivable and accounts payable. Based on the systematical analysis of empirical data, consisting of the financial figures of 161 companies operating in the value chains of the automotive, pulp and paper, and ICT industries, the study introduces a generic framework for working capital models. The framework includes six generic working capital models and one sub-model, and offers a holistic view of working capital management. The study takes the initial step towards tightening collaborative actions between value chain partners regarding working capital. The introduced framework offers a managerial tool for analysing the material and financial flows at the company level as well as in the inter-organisational context.

    Abstract: The purpose of this study is to simulate the cutting corners chain as a criterion in controlling the quality control of health services. These services are in a healthcare chain based on human resources (HR). This chain study included three clinics in a specialised hospital, whose doctors were considered as service providers. In this study, system dynamics (SD) approach is used for simulation. After modelling and formulating the problem, the validation of the designed model was confirmed and based on the simulation results; appropriate policies to match supply and demand were established. Also methods to cope with cutting corners chain were identified in a dynamic environment. They are based on sensitivity analysis, changes in patient arrival rates and human resources service capacity. The designed model with some slight changes could be used in hospital management in the field of human resources management, with a dynamic and systemic thinking, either as a unit or as a healthcare service chain.

    Abstract: The aim of this study is to analyse the relationship between government and public sector universities in the perspective of agency theory and propose a theoretical framework that will highlight the various aspects of the principle and agents. In this perspective government plays a main role as principle while public sector universities are as agent and this relationship is known as agency theory. This relationship normally has two major issues such as goal conflicts and information asymmetries. Correspondingly, in this review paper, systematic approach, and content analysis approach has been adopted. The reviewed literature revealed that the government provides performance based grants to the public sector universities so government have pursue some expectations from public sector universities like accountability and transparency of the funds. Similarly, it has been highlighted that to verify the relationship between government and public sector universities in the context of agency theory because there is a sheer need to conduct empirical research studies.

  • Exploring the link between inventory and working capital through variability reduction across a food-based CPG supply chain   Order a copy of this article
    by Mohan Gopalakrishnan, Srimathy Mohan 
    Abstract: The global uncertainties regarding the timing and type of economic recovery have made firms relentlessly focus on managing their working capital in a prudent manner. It is widely acknowledged that effective supply chain management practices can reduce operating costs and logistics expenses, significantly affecting a company's working capital. In this case-study, based on data from a real-world company that manufactures and distributes packaged food, we explore examining the variability across the supply chain (supplier-manufacturing-distribution). We specifically focus on mapping end-to-end supply chain variabilities and analyse ways to manage demand variability and forecast accuracy, operational variabilities in plant and the role of managing changeovers and centralisation vs. decentralisation of safety stock to manage distribution variabilities. Our study clearly pointed to forecast accuracy and arrival variability at production to be the two major performance-altering variables. Improving forecast accuracy was contingent on sharing and integrating information on promotions with production planning. Other variability inducing variables included changeovers and distribution safety stocks. Managing these further improves the working capital.

    Abstract: Multi-criteria group decision-making approaches with fuzzy theory are trendy in the area of decision science. Frequently decision makers express their judgment linguistically. This study aims to categorise the student's basic knowledge level in order to provide pre-placement training for the students in the placement. A method is constructed using several linguistic values with different weights using the fuzzy number grading system. An algorithm for fuzzy multi-criteria group decision-making (FMCGDM) is proposed with the notion of hendecagonal fuzzy number (HDFN) and symmetric hendecagonal fuzzy number (symmHDFN). Also, complex proportional assessment (COPRAS) method is used for group decision-making approach, to assess the performance of students in the pre-placement training. Based on the report generated, the college can arrange varying levels of training using fuzzy decision theory.

    by Zahra Namazian, Emad Roghanian 
    Abstract: One of the most significant decision-making processes is the site selection. If the site correctly selected, the access for the best customers as well as the greatest market potential would be guaranteed. Bank branch optimal location is one of the most significant strategic issues in the competitive market especially for private banks because of the global competition and high customer expectations. This study presents a geographic information system (GIS)-based model for locating suitable sites for making new branches by using data sources. Also, maximal covering location problem (MCLP) was used to select branches that the maximum demand might be reached within a pre-specified target travel time. The model was implemented for Ansar Bank in Isfahan, Iran. The criteria were restricted through demographic attributes, competition, transportation, flexibility and cost in GIS mapping approach. Finally, the results illustrated the efficiency and applicability of the proposed integrated method.

    by ASHISH YADAV, Sunil Agrawal 
    Abstract: Multi-manned assembly lines are designed to produce high volume products. In this paper, multi-manned assembly line balancing problem (MALBP) is addressed in which a group of workers simultaneously performs different tasks on a workstation. A tricycle company data is used to solve the problem with the objectives of minimising the cycle time and number of workstations. The problem is solved in two stages. In the first stage, the problem is solved with the objective of minimising the cycle time. The output from the results obtained is used in the second stage to minimise the number of workstations. A mixed integer programming formulation for the problem is proposed and is solved using Lingo 16.0. Since multi-manned assembly line balancing problem is NP-hard, it is first tested on a set of test example problems and is later on applied to solve the tricycle case study problem. The results show that the numbers of workstations are reduced which leads to a reduction in the number of workers and idle time.

    by Prasanna Kumar Kukkamalla, Andrea Bikfalvi, Anna Arbussà, Martinsuo Miia 
    Abstract: Changes in urban travel behaviour, customer perception of car ownership, and government policies support the rise of mobility services. Car manufacturing firms have joined this new service ecosystem, which is complex in nature and requires collaboration between several actors. Scholars have explored these mobility services, but knowledge about how a firm initiates and expands its mobility service network, and how the activities of the different actors are deployed within it, is still limited. Hence, this study aims to shed light on how a car manufacturing firm creates and develops its mobility service network, and to define the key actors and their activities in it. The actor-network theory framework and the document analysis theory are used to interpret the empirical observations and generate the empirical evidence, respectively. The findings reveal the evaluative process of the mobility service network and who the actors who join the network by offering their core business services are. The study concludes by presenting a new actor category, namely co-branding actors.

    by Osama Abdelkader, Sherif Attallah 
    Abstract: Multidisciplinary research is a practical approach to address one of the most important global challenges, that I shortage of resources shortage. There is a research gap in the area of sustainability, where engineering studies are concerned with physical aspects, while marketing studies explore aspects of human behaviour with/against environmental friendliness, separately. Furthermore, scholars should pay more attention to the differences among human generations. Therefore, this paper presents a comparison between the extent of behavioural and attitudinal loyalty among generations toward green buildings especially residential buildings, which represents the highest energy consumption in the world. The current study is questionnaire-based, and it was tested through a group of validity and reliability tests. SPSS V21 was used to analyse the collected data from 1,589 participants. The study presents a set of findings and recommendations that contribute to better understanding of human behaviour in the context of rationalisation of natural resources. Finally, a group of future researches were suggested to study more comparisons depending on cross-cultural, cross-national and gender differences across a wider range of interdisciplinary studies.

    by Muhammad Rosiawan, Mosel L. Singgih, Erwin Widodo 
    Abstract: This paper aims to measure the overhead costs and economic effects of applying ISO 9001 clauses in manufacturing companies. The activity-based management (ABM) approach is used to allocate cost objects and to trace the source of costs for high-cost activities when implementing the ISO 9001 clause. Inbound logistics processes, which consist of purchasing raw materials and warehouse processes, were used as the research objects for implementing the ISO 9001 clause. From the results of the numerical calculations based on the conceptual models and mathematical equations developed, the company obtained cost savings first from a reduction in high-cost activities and second, from the performance targets achieved. However, companies need to consider the number of performance indicators in the business processes precisely. This is because it affects the cost savings obtained and the return period of investment in the ISO 9001 implementation programs.

  • A dynamic literature review on lean and agile supply chain integration using bibliometric tools   Order a copy of this article
    by Ibrahim. O. Raji, Tommaso Rossi, Fernanda Strozzi 
    Abstract: As competition continues swinging from individual 'company level' to 'supply chain (SC) level' courtesy of diverse and erratic customer behaviour in this globalisation era, survival of such SC is hinged on careful adoption of strategies aligned with organisational goals. Lean and agile are critical strategies because the former ensures efficient use of resources while the latter involves matching supply with demand in turbulent/unpredictable markets. Careful adoption of both strategies will lead to SC performance improvement. This paper aims at advancing their understanding by conducting an intensive scientific literature review to unravel the state of art of lean-agile SC by examining the procedure of knowledge conceiving, transmission, and development from a dynamic viewpoint. To achieve this, a dynamic cum quantitative review technique named 'systematic literature network analysis (SLNA)' is applied. The investigation enabled unravelling research directions/ emerging themes in the lean-agile field thereby supporting researchers/ newcomers to target specific themes to explore.

    by Mohan Gopalakrishnan, Srimathy Mohan 
    Abstract: The availability and delivery of blood can make the difference between life and death; hence, the blood supply chain must have smooth inventory flows. We examine how to accomplish this by analysing non-blood inventories, which are the supplies needed for blood collections, testing, and storage. We investigated non-blood inventory pre-positioning through a research partnership with the American Red Cross (ARC). The goals for the research project were to optimise the ARC's facility location and inventory allocation decisions. Using data from the ARC, we empirically formulated a fixed-charge model to solve the location-allocation problem. The results indicated that the ARC should both shut down and construct warehouses to attain cost savings of 9%. We also conducted sensitivity analyses with respect to demand and cost. Finally, we review our contributions to the literature on humanitarian logistics and blood supply chain, and we conclude by outlining future research opportunities.

    by Abdol Hamid SafaeiGhadikolaei, Mojtaba Aghajani, Hassan Ali Aghajani, Mohammad Valipour Khatir 
    Abstract: In this paper, a fuzzy mathematical programming model based on the Nested model is proposed to design a sustainable multi-product, multi-period supply chain network (including three parts of the procurement, production and distribution) under the competition and uncertainty conditions. Sustainability measures are carried out using previous studies and the Supply Chain Operations Reference (SCOR) model is extracted in each of the sustainability dimensions and then localized using the Fuzzy Delphi method. In order to determine the relationship between indicators and the importance of each index, DEMATEL method is used and then the obtained fuzzy model is converted into a crisp one. To demonstrate the efficiency of the model, a real example is presented in the refractory industry. Finally the results are analyzed and suggestions are presented.

  • Customer Satisfaction and Loyalty in Malaysian Resort Hotels: The Role of Empathy, Reliability and Tangible Dimensions of Service Quality   Order a copy of this article
    by Guru Prabhakar, Si Ni YEONG, Dan Knox 
    Abstract: This paper applies the SERVQUAL model for the purpose of examining the impacts of the five dimensions of service quality on customer satisfaction and customer loyalty in the hotel industry in Malaysia, and to investigate which factors among said dimensions (tangibles, reliability, responsiveness, assurance and empathy) have a major role in affecting customer satisfaction and loyalty in relation to resort hotels. Questionnaires were used to collect quantitative data for this research by deploying a random sampling strategy to invite 136 hotel guests to complete the survey. The key findings indicate that empathy, tangibles and reliability have significant roles in affecting overall customer satisfaction in the Malaysian resort hotel sector but that responsiveness and assurance were not significantly influential. Empathy was the most significant predictor of customer satisfaction among all of the dimensions, and customer satisfaction has a positive relationship with customer loyalty in this context.

    by Sangita Dutta Gupta, Mafruza Sultana 
    Abstract: Women play a significant role in development of any economy. An economically strong society can be built only if women are provided with equal opportunities as men. The Mc Kinsey report has shown that companies with more women in decision- making areas tend to do better than companies with less women representative. Thus, it is imperative that women participation in work force increases. This has positive impact on economic growth of the country. Data was collected through primary survey. The questionnaire was circulated among the women professionals and they were asked if they were able to fully exploit their potential to meet their aspirations and maintain work life balance. The study identified important determinants of work life balance. Another survey was conducted among HR of different companies to understand about the gender inclusive policies of their organizations. The study has important implications for the future research and policy measures.

  • Scheduling and short-term demand forecasting in an on-demand ride service industry   Order a copy of this article
    by Ritesh Adhyapak 
    Abstract: Demand for cabs in transportation companies fluctuates at different times of the week and therefore predicting the future demand during peak days is critical to save costs and undergo proper scheduling of cab drivers. The paper reviews the use of demand forecasting using time series modeling to forecast the best technique to predict future demand using moving average, exponential smoothing and multiplicative seasonality method. Arena simulation is done using Poisson distribution to simulate the waiting time of customers to book a cab. The modeling approach is undergone in a cab service company which showed that forecasting by multiplicative seasonality method produced the best results with minimal error in MAD, MSE, and MAPE. This shows that transportation companies have a seasonality factor in the number of trips that it undergoes and can use multiplicative seasonality modelling to best analyze short term and long term demand in cabs.

    by Mahesh Prabhu H, Nikhil Agrawal, Dhruv Sangwan 
    Abstract: Higher education institutes play a crucial role in the all-round development of students. The campus infrastructure, academic facilities, administrative support, international collaborations play an important role in a students success. Extant literature also suggests that leadership style adopted by the professor also impacts student motivation and student satisfaction. Thus, this paper studies the impact of student perceived service quality on student motivation and student satisfaction in higher education institutes in India with leadership style adopted by the faculty as a moderator. A survey is conducted among students of higher education in India to capture their perception about service quality of their institute, satisfaction, motivation and leadership style of the faculty member. Structural equation modelling was used to analyse the data. Results indicate that service quality significantly influences only student satisfaction but not motivation and leadership style of the faculty does not moderate the relation. Conclusions are drawn and implications are highlighted to enhance students experience at higher education institutes.

    by Tiina Puolakka, Petra Pekkanen, Timo Pirttilä 
    Abstract: In professional services there exists a duality in controlling the workflow between professionals and managers who both have partly different perspectives and preferences. The purpose of this paper is to empirically explore what are the roles and tasks of professionals and managers in workflow control and how these two actors interact. The study is executed as a single case study applying grounded theory as a research method. The case organization is the Insurance Court of Finland, which presents a distinct setting for studying workflow control due to its highly individual-centered nature, which yet has also features of mass services. The findings describe the way workflow control happens in interaction between managers and self-managing professionals. Professionals have great autonomy in workflow control but it is limited to concern only their own case-handling silos. Managers have several roles in workflow control, which are related in different ways to professionals’ self-management.

    Abstract: This theoretical paper presents the dual dimension of performance measurement as the traditional and contextual perspectives with focus on operational performance indicators. This study argues that the business environment is an important factor to consider when carrying out performance assessments in manufacturing firms. This view is based on the knowledge that different contingencies are experienced in different business environments especially the developing and developed countries’ contexts categories. Using the contingency theory as the foundation of this argument, operational performance indicators for evaluating the performance of manufacturing firms should be composed of both traditional and contextual assessment components.

  • Impact based disaster classification: A prerequisite for planning and operations of humanitarian supply chain   Order a copy of this article
    by Lijo John, G. Anand 
    Abstract: The classification of disasters has far reaching consequences on policy making and developing preparedness plans in humanitarian supply chain (HSC). The policy makers try to understand and focus on a few major types of disasters that require their attention to appropriately utilise the scare resources. This has led to the development of multiple classification schemes for disasters. However, the existing schemes are often subjective in nature and fail to capture a holistic impact of disaster on the lives of the affected people. This paper addresses this gap by proposing a composite impact indicator (CII) to measure the impact of the disaster and classify them based on the risk of impact. The proposed classification schema uses the data from emergency events database (EM-DAT) and classifies the natural disasters on a two-dimensional matrix based on CII and relative frequency of occurrence. This classification schema would assist policy makers specifically the government agencies to suitably allocate resources among the stakeholders, specifically for high impact disasters during preparedness phase. Furthermore, it would also help in improving the coordination between the stakeholders during the preparedness phase of HSC and thereby play a significant role in improving the effectiveness of the activities during the relief and rehabilitation phases.

  • Using Time Motion Study to identify the determinants of Patient Satisfaction and impact of Long Appointment Wait Time: An Empirical Case of Radiology department   Order a copy of this article
    by Amandeep Dhaliwal 
    Abstract: Long waiting time is an annoyance to the patients and it leads to negative perception of service provider. The study examined the determinants of patient satisfaction index with imaging services being provided by the healthcare provider with an emphasis on the waiting time and service time and overall average waiting time for the patients in Radiology department. A cross-sectional time study was conducted using single blind observance of patients who visited the radiology department. Further, Root Cause Analysis (RCA) of the factors leading to longer wait time was undertaken. The results revealed that longer waiting time was negatively associated with patient satisfaction regarding several aspects of the care they received. It is not always possible to prevent dissatisfaction with waiting times by increasing resources such as increasing staffing. However, Corrective and Preventive Action (CAPA) based best practices and recommendations are outlined to ensure lesser waiting time and higher patient satisfaction.

  • Exploring the Impact of Orientations on Hospital-supplier Collaboration: An Empirical Study   Order a copy of this article
    by Santanu Mandal, Sreejith Nair, Arjun Sreedhar, Uthra Vijeshwari 
    Abstract: With increasing complexity in healthcare service supply chain operations, there is a dire need to critically examine the enablers of collaboration in a hospital-supplier setting. While studies have stressed the importance of collaboration in service SCs, still the importance of strategic orientations are yet to be explored in the development of hospital-supplier collaboration. We focused on four such strategic orientations relevant for healthcare SCs: technology orientation, supply chain orientation, learning orientation and environmental orientation in developing hospital-supplier collaboration. Furthermore, we also explore the inter-relationships among these orientations. Perceptual responses collected from 92 hospital managers were analysed using SmartPLS 2.0.M3. Results suggested technology, supply chain and learning orientations as prominent enablers for hospital-supplier collaboration. Environmental orientation may inhibit the collaboration process if both parties do not agree on environmental issues. Implications were provided for theory and practice.

  • Knowledge Base and BOTs- Redefining Workforce Estimation Model   Order a copy of this article
    by VARSHA DEB, Vasudha Vashisht, Nidhi Arora 
    Abstract: Workforce estimation has always been a challenging task for service organizations. The revenue and profits are directly impacted by the number of resources deployed, thus accurate workforce estimation becomes a key objective for any service. With time many organizations are taking leap in implementing BOTs or implementing Knowledge Base for reusability, the workforce estimation also needs changes. This paper first presents application of forecasting models to estimate the workforce requirement for an IT service organization. As many organizations are promoting the culture of knowledge reuse, this paper later presents how the same model can be modified to forecast the workforce when an organization implements a Knowledge Base (KB) for resolving customer’s requests / incidents. A detailed implementation of this model is presented using MS Excel. The model presented is generic in nature and can be reused by other organizations having similar type of work or requirement.

  • Horizontal Collaboration in Oligopoly Supply Chains   Order a copy of this article
    by Sonu Rajak, Parthiban Palanisamy, R. Dhanalakshmi 
    Abstract: Oligopolistic markets are those in which a few numbers of firms produce and markets similar products to similar markets and customers and this group of few hold a huge market share. Since these oligopolistic firms already have effective penetration in distribution lanes, there are areas where these firms can co-operate while competing with others. This paper aims to check the feasibility of horizontal collaboration on transportation for these oligopolistic firms by conducting a study on a 3-Firm 4-Zone case model. The study uses Mixed Integer Linear Programming model to harness the potential of load bundling and backhauling optimization when transportation load demands of these firms are merged. The competitive and co-operative scenarios are compared using different performance measures like cost savings, reduction of no of trips and asset utilization. Also, effort is taken to ensure the model is framed on the real case scenarios present in the Indian transportation industry.

  • Modelling queues at ferry stations: principles and application   Order a copy of this article
    by Iñigo L. Ansorena 
    Abstract: It is well known that the flow of passengers at ferry stations is characterised by random variations following ferry schedules. Recognising the need to manage congestion, an approach based on queuing models is proposed. The motivation for this type of modelling comes from the short term, where the knowledge of bottlenecks is essential for efficient facility management. An empirical case study is presented to explore the effectiveness of the queuing model and reveal waiting times, service times, queuing duration and service levels. The methodological framework proposed in this paper sheds new light on service points and is therefore a good starting point for improving processes at peak times. In addition, the queuing model can be used to simulate more complex scenarios in the future.

    by Rajagopalan Sridharan, E.N. Anilkumar, Ram Kumar 
    Abstract: Implementation of sustainable practices in healthcare sector is important due to environmental and social impact of hospital operations. In the present study, the barriers in implementing sustainable practices in the public healthcare sector are prioritized using an integrated DEMATEL-ISM-PROMETHEE approach. The barriers are identified through literature review and discussion with experts from the public healthcare sector in an Indian state. The inter-relationships between the various barriers were identified through the DEMATEL methodology. The driving power and the dependence power among the barriers were obtained using the interpretive structural modelling method. Finally, the prioritization of the barriers was achieved through the PROMETHEE method. The study shows that lack of support from supply chain members, lack of commitment from top level hospital management and ignorance about government rules and regulations among employees are some of the significant obstacles in adopting sustainable practices in the public healthcare hospitals in the Indian state.

    Abstract: This study reported the relationships between Competing Value Framework (CVF) model of organizational culture and job performance through the mediating role of high-performance human resource (HPHR) practices. A quantitative research approach was adopted and data was collected through structured questionnaires from employees working in public telecom company in Pakistan. The Partial Least Square Structural Equation Modelling was employed for the analyses. The results of the study showed that three culture typologies of CVF; adhocracy, market, and culture have significant effects on job performance while hierarchy culture has an insignificant influence on job performance. Extensive training and incentive reward partially mediated the relationships between market culture and job performance. Furthermore, relationships between clan culture, market culture and job performance were partially mediated by selective staffing and extensive training. The CVF model of organizational culture provides a supportive framework for enhancing job performance through HRPR.

    Abstract: This paper discusses a single server retrial queue with two phases of service of which the second phase is optional. Further, the server is subjected to starting failures and takes K types of Bernoulli vacations. A necessary and sufficient condition for the system to be stable is investigated. The joint probability generating function of the system size and the server states are obtained using supplementary variable technique. Some of the existing results are deduced as special cases. Further, significant system performance measures such as mean system size, mean orbit size, server utilisation and probability of the orbit being empty are derived. The stochastic decomposition law is shown to hold good for this model also. Finally, extensive numerical illustrations are provided to showcase the effect of the parameters on the system performance measures.

  • Deciding on inventory allocation policies in the auto parts Brazilian distribution chain   Order a copy of this article
    by Fabio Cardoso, Maria Lucia Galves, Jose Vieira 
    Abstract: The purpose of this paper is to evaluate the decision regarding whether to centralise or decentralise the stock of auto parts in Brazilian context. Extensive research was conducted regarding stock allocation policies, with a focus on centralisation and decentralisation, whereas the criteria for this decision were actually validated according to the opinion of Brazilian dealerships. A survey of 119 dealers revealed the important criteria for decision making using the analytic hierarchy process (AHP) approach. Our results demonstrate that dealerships assign high importance to delivery lead time, quality and flexibility in the delivery process from automakers. The results reveal that the simple trade-off between service level and inventory cost does not offer a definite distribution net design regarding stock allocation policies. This paper contributes by showing the criteria relate to different types of stock allocations influence the decision regarding whether to centralise an auto parts distribution chain in Brazil.

    Abstract: The purpose of this research is to analyse the dimensionality of the concept of customer perceived value in the banking and financial services sector. A total of 300 customers of financial entities were surveyed and structural equations models were used to verify the reliability and validity of the scale of perceived value. Perceived value is found to be a multidimensional construct composed of five dimensions: technology, professionalism, physical environment, emotional value and social value. A scale of overall perceived value in financial services was obtained, composed of five dimensions and represented by 22 items that are significant for their measurement. The validated scale can help the managers and strategists in the banking and financial services sector to frame marketing strategies according to the perceived value of their customers. As no other study with comprehensive development of a multi dimensional perceived value measurement scale was identified, this study recommends a validated scale to measure the customer perceived value in Indian banking and financial services sector.

  • Analysis of post-harvest supply chain impediments for rural employability and waste reduction   Order a copy of this article
    by Srikanta Routroy, Girish Kant Garg, RAHUL PRIYADARSHI 
    Abstract: The tremendous amount of economic losses, welfare losses and distress among the farmers due to produce spoilage and quality losses are a few major concerns in the Indian post-harvest supply chain (PHSC). A study for identifying and analysing the impediments in the post-harvest supply chain was performed to minimise them. The interpretive structural modelling (ISM) was applied on the identified impediments to analyse the interactions among them and matrix cross-reference multiplication applied to a classification (MICMAC) analysis was used to categorise the impediments into four clusters on the basis of driving and dependence power. The key impediments obtained from the analyses are lack of government support, lack of transportation infrastructure and lack of fixation of minimum support price and its revision are to be improved with time to improve farmer profitability, rural employability and waste reduction. These impediments appear at the bottom in structural analysis thus hold a prime value among the identified impediments. The utility of this study is stated in the practical implications section, i.e., adaption of value addition practices for onion to reduce the spoilage ratio.

  • VMI Adoption in Automotive Industries: Two Different Perspectives   Order a copy of this article
    by Mohammad Juned, Jamal A. Farooquie 
    Abstract: Vendor managed inventory (VMI) is a collaborative approach to manage inventory-related issues. In this method, the vendor has the privilege and accountability of stock replenishment decisions through consistent automatic inventory or sales data from the buyer. This study attempts to explore critical VMI factors among the buyers and the vendors in Indian automotive supply chains. An attempt is made to compare how professionals and academia perceive VMI implementation. Two separate questionnaires formulated one for the corporates and another one for the academia. The Wilcoxon signed-rank test employed for comparing corporates (buyer & vendor) and academic view towards VMI. Further, the t-test used to investigate any significant difference for challenges and facilitators between the buyers and vendors. The outcomes from this study may help the automotive industry make a positive and efficient relationship between buyers and vendors and thus enhance the supply chain efficacy.

  • Buffer size evaluation in a bottle plant production system: a comparison between different solving methods   Order a copy of this article
    by Daria Battini, Ilenia Zennaro, Serena Finco, Riccardo Aldrighetti 
    Abstract: The Buffer Allocation Problem (BAP) is a crucial research issue in designing manufacturing systems. Several methods have been proposed including simulation modelling, exact and heuristics approaches. Simulation is usually time-consuming and requires expensive software; analytical approaches necessitate specific knowledge that is uncommon in companies, especially among small-medium enterprises (SMEs). Thus, practitioners generally develop empirical methods based on their experience, to get buffers size with easy-to-use procedures. This paper proposes a comparison between three BAP approaches: an empirical method, a simulation method, and an experimental formula, all applied in a real case study. Simulation approach leads to a great optimal solution, but it requires to buy the software and time to build the model. The empirical method requires a shorter time but the buffer size results in severe additional costs. Finally, the experimental formula proves to be a good trade-off between the obtained buffer size and the efforts addressed its application.

    by ANNAYATH MAQBOOL, NOOR ZAMAN KHAN, Talhah Shamshad Ali, Zahid Akhtar Khan, Rajesh Attri 
    Abstract: Comfortable seating while travelling by automobiles has become a necessity for occupants, rather than a luxury. Seating comfort is essentially important for health and safety of the automobile passengers. Several factors influence human seating comfort and therefore, this paper identifies them through comprehensive literature survey. Thirty-two such factors are identified, and they are categorized in five main categories. Subsequently, optimal weights of these factors are computed using a novel multi-criteria decision making (MCDM) method i.e. the best-worst method (BWM) based on which they are ranked so as to establish their importance with respect to human seating comfort. Further, sensitivity analysis is carried out to ensure robustness of the ranking results. This study is expected to assist design engineers and researchers in understanding the importance of the factors affecting human seating comfort in automobiles so that they can tackle them strategically to provide the desired seating comfort to the occupants.

    by Vishwesh Singbal, Gajendra Kumar Adil 
    Abstract: Travel time is a predominant performance measure of AS/RS in literature. Two basic approaches are available for modelling travel time: discrete and continuous. Continuous models involve approximation of travel time. This paper considers a single crane unit load multi-aisle AS/RS operating under a single command and one of the three storage policies. The performance of continuous model is compared with discrete model under different operating conditions characterized by different combinations of input parameters: number of aisles, storage rack shape factor, number of products and demand skewness. Through the comparison of percentage error of continuous model different configurations where continuous models perform well are identified.

  • Exploring the effects of lean practices and supply chain disruption on performance   Order a copy of this article
    by Kihyun Park 
    Abstract: Lean practices have been a dominant approach in dealing with business and supply chain issues for the last few decades, but many studies suggest that the leaner the supply chain process, the more vulnerable the supply chain network. This study aims to explore the relationship between lean practices and supply chain disruption occurrences (SCDOs) and their impact on firm performance. In a large-scale survey of 198 companies in the U.S., structural equation modelling was used to test the proposed hypotheses. The results of this study suggest that lean practices can promote a firm’s operational performance directly, but they can conversely decrease a firm’s operational performance by increasing SCDOs. This study contributes to the literature of lean practices and supply chain risk management and provides practical implications by extending our understanding of the positive as well as negative sides of the lean approach in operation and supply chain practices.

    Abstract: Simultaneous Delivery and Pickup vehicle Routing Problem with time windows constrained is studied to improve the performance of logistics management for transporting goods by determining optimum vehicle routes. In forward supply service, a quantity of product is delivered to each customer and another quantity is picked up from customers as a part of reversed logistics. The objective of this model is to determine the efficient vehicle route under cost optimisation including fixed cost, variable cost and penalty cost for being tardy. This study proposes a hybrid genetic algorithm which incorporates three different heuristics for generating initial solution including sweep algorithm, time oriented heuristics and swap heuristic. In order to evaluate the performance of the proposed hybrid genetic algorithm, a comparison study is made with existing genetic algorithm. The results show that the performance of HGA is superior to that of GA in terms of the total cost consumption of vehicle.

    by Rajagopalan Sridharan, K.K. Eldose, Bharat Dhage Mayureshwar, K. Ratna Kumar 
    Abstract: In the global competitive environment faced by educational institutions, operational excellence enables world-class performance. An important task of education planning involves determining the academic progress of students. The present research focuses on the development and analysis of a Markov model to evaluate the academic performance of students in a four-year engineering programme in an institution located in India. Initially, the transition probability matrix is developed for the academic progress of students using the frequency matrix obtained from historical data. The probability of movement of students between successive years of the academic programme is computed using the transition probabilities. Using Markovian process, the expected number of years spent in a specified transient state before absorption and the probabilities of absorption are determined. The analysis of results reveals that remedial classes and mentoring activities have played a significant role in increasing the graduation probability as well as decreasing the withdrawal probability.

    Abstract: Drawing on upper echelon theory and the resource-based view, this study examines the impact of CEO human capital on economic corporate performance. Our sample consists of 561 Vietnamese firms listed on Ho Chi Minh and Hanoi Stock Exchange, over the period from 2009 to 2015. We use a wide range of components of CEO human capital, including CEO’s educational background, generalist skills or specialist skills, experience (foreign experience, working experience in state-owned enterprises, age, and the number of years in CEO position), social relationship and gender. We document that several aspects of CEO human capital influence significantly corporate economic performance. Based on the historical background of Vietnamese listed firms, we conduct further analysis for both groups of firms, state-owned and non-state-owned, and find that there are some differences in the impact of CEO human capital components on firm performance between the groups.

    Abstract: Field service management (FSM) is to manage and mobilise technicians to customer locations for maintenance of assets. Increasing competition and decreasing margins force manufacturers of industrial equipment to augment with effective field service planning. Technician selection and allocation are essential cornerstones of field service planning. Efficient delivery of field services is a challenging task. Decisions are typically made under a dynamic and uncertain environment with assets installed at geographically dispersed locations. Researchers have explored the heuristics, algorithms and knowledge-based analysis for decision making in technician selection and allocation. Attention is sought to find methods for addressing the selection and allocation of technicians comprehensively. This paper presents a hybrid approach combining the analytic hierarchy process (AHP) integrated with mixed-integer nonlinear programming (MINLP) model to rank and allocate technicians to spatially distributed field services. The objective is to minimise the field service fulfilment cost. An example of a power generating company is presented.

    by Virupaxi Bagodi 
    Abstract: The complexity is growing continuously due to the exponential growth in technological innovations. The managers in a business setting find it hard to manage a problem as it does not come alone; it is connected to another set of subsystems. This could be the reason why the list of Fortune 500 companies keeps changing. The mortality rate of the small and medium enterprises in India is also on the rise. The dynamic complexity is hard to handle and requires a radically different approach. System dynamics has been widely used to capture dynamic complexity due to its ability to capture nonlinear relations, delays, interrelations, and interaction among all the elements in a system. A case study was conducted in a service organisation employing system dynamics methodology. It has been systematically demonstrated through policy experimentation how managers fall prey to quick fixes in the real world setting.

Better access to large amounts of information, improved algorithms, and advanced hardware systems have led to artificial technology development. Artificial technology has supported business organisations to enhance their data collection abilities with the rapid advancement of different tools. If a product depends on supplies from multiple suppliers, disruptions can have subsequent effects. Organisations must redesign supply chains, improve flexibility, and re-evaluate the relationship with suppliers to reduce systematic risks. The methodology used in this study is a critical review of previous literature related to this topic. We searched the articles in the English language by following general research procedures. We manually searched different relevant articles from EBSCO, ProQuest, Emerald Insight, Science direct, Taylor & Francis, Wiley, JSTOR, and IEEE. The findings present the significant functions of artificial intelligence on sustainable supply chain management in the COVID-19 scenario. Future research perspective is also discussed.

    Abstract: This study intended to investigate the impact of using e-government on rebuilding the trust of citizen in the government through suggesting satisfaction with e-services as an intermediary variable. A descriptive-quantitative-exploratory approach was adopted by designing a self-administrated questionnaire for data collection purposes. Through convenience sampling, data was collected, and the sample comprised 397 individuals, who are citizens and users for e-government in Jordan context. Smart-partial-least-squares was adopted for analysis purposes. Results reported a significant direct impact for e-government using on rebuilding citizen trust (R2 = 26.1%), and a significant impact for e-government using on promoting satisfaction with e-services (R2 = 57.3%), and a significant impact for satisfaction with e-services on promoting citizens’ trust (R2 = 41.3%). The analysis also reported a significant indirect effect (0.452) supporting the suggested role for satisfaction with e-services as a full mediator. Following the gathered results, directions and recommendations for future studies were provided.
