  •   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 firm's 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.

    by Guilherme Tortorella, Najla Alemsan, Alejandro Francisco Mac Cawley Vergara, Rapinder Sawhney 
    Abstract: This study aims at identifying the existing methods for materials planning and control applied in healthcare organisations. An extensive literature review was performed in the main databased based upon two research axes: 1) materials planning and control, and 2) health services. Besides the content and bibliometric analysis, literature evidence was analysed from the perspective of two theoretical lenses: types of flow of value and complexity levels of hospital departments. Results from this review allowed the indication of two main research directions; they are: 1) integration among methods for materials planning and control, and 2) financial assessment of the implementation of materials planning and control methods in hospitals. The healthcare sector is highly important due to the criticality of it is quality, safety concerning patient care and the high cost involved in its operations. Furthermore, resources are usually limited, complicating its management.

    by Mohammed Iqbal Al-Ajlouni, Nawaf Alghusin 
    Abstract: The concept of investor sentiment deals with the psychological attitudes the investor has toward the security of the fiscal market or a related certain situation; accordingly, different antecedents and determinants make-off that attitudes. The current paper explores antecedents for investor sentiment (IS) in Amman Stock Exchange (ASE) using investor sentiment index (ISI) utilising SEM approach. Data was collected through surveying 401 current and potential investor in ASE through no probability purposive sampling using a self-administrated questionnaire. SEM using AMOS was employed and the result reported that the suggested ISI sufficiently predicted IS in Jordan setting as explained 62% of the achieved variance; moreover, IC was identified as the strongest antecedent along with PC, whereas SC and MC were identified as negative antecedents, and accordingly, the implication was discussed.

  • Simulation of Cutting Corners Chain in Healthcare Services   Order a copy of this article
    by Alireza Pooya, Ali Alizadeh Zoeram, Zahra Naji Azimi, Ali Vafaee Najar 
    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.

  • Multi-Manned Assembly Line Balancing Using Exact Solution Approach -A Case Study of a Tricycle Assembly Line   Order a copy of this article
    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.

  • Creating and developing the actor-network for a manufacturing firm’s mobility services   Order a copy of this article
    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.

  • Blood Supply Chain: The impact of Facility Location and Inventory Allocation Decisions for Non-Blood Inventories   Order a copy of this article
    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.

  • A Fuzzy Mathematical Programming Model for Sustainable Supply Chain under Competition and Uncertainty Environment   Order a copy of this article
    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.

  • Work -life Balance of Women Professionals: Impact and Implications   Order a copy of this article
    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.

  • Impact of Student Perceived Service Quality and Faculty Transformational Leadership on Student Satisfaction and Student Motivation: An Empirical Study   Order a copy of this article
    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.

  • 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.

  • 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.

  • 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.

    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.

  • 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.

  • 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.

    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: 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.

  • How to increase access to kidney transplantation: the analysis of a Brazilian public hospital through operations management   Order a copy of this article
    by Ana Carolina Pereira De Vasconcelos Silva, Thais Spiegel, Luiz Felipe Roris Rodriguez Scavarda, Augusto Da Cunha Reis 
    Abstract: End-stage renal disease is one of the most costly chronic diseases for the Brazilian public health system. Dialysis is still the most commonly used procedure, even though transplantation is one of the most recommended treatments. Considering the perspective of operations management as an approach for organisational interventions, the objective of this paper was to propose a new operation model for a transplantation unit in Rio de Janeiro State focused on reducing the patients waiting times in queues. The first step was to conduct a systematic literature review. Then, the kidney transplantation process was modelled using ARIS/IDS notation, which oriented the description and analysis of the operation model of the transplantation unit. A new model was proposed, along with a list of strategic, structural and political decisions to mitigate organisational, network design and budget pass-through logic inconsistencies.

  • A Small Service Enterprise: System Dynamics Study   Order a copy of this article
    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.

    by Muhammad Usman Tariq 
    Abstract: The purpose of the paper is to investigate the functions of artificial intelligence in supply chain management. In recent years, artificial intelligence framework has accomplished human-like performances in various previously considered computationally impossible tasks. 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: In this study, the role of in-store logistic operations is examined on customer satisfaction and loyalty in Pakistan. Disconfirmation expectation theory is adopted because customer satisfaction is the result of their expectation and shopping experience. Data from 201 respondents is collected via interception method and PLS-SEM was applied for the analysis. Results show that customer perceived in-store logistics has direct and positive impact on satisfaction and loyalty. Therefore, by improving in-store logistic activities, customer satisfaction can be enhanced. Results also show that customer perceived in-store logistic performance has no impact on store image, so store image does not have mediating effect in this study. Moreover, the role of customer satisfaction as mediator was found which highlights the importance of satisfaction in the process of providing efficient in-store operations for making more customers loyal. Based on findings, a thorough discussion is reported whereas the managerial implications are also discussed.

  • The Work-Life Balance and Job Satisfaction   Order a copy of this article
    by Álvaro Dias, Carolina Feixeira, Leandro Pereira, Renato Lopes Da Costa, Rui Gonçalves 
    Abstract: The promotion of an internal environment marked by a positive and stable context contributes to the employees sense of belonging to the organisation. As such, it is increasingly important to enhance commitment and professional satisfaction, and at the same time, allowing their employees to achieve a balance between their professional and personal life. Using a quantitative study based on a survey sample of 262 workers, our findings reveal that the organisational environment positively affects job satisfaction. Furthermore, results indicate a strong and relation between organisational engagement and employee satisfaction. However, no significant relationships were found between organisational commitment and between professional and personal life balance. It was also found that organisational commitment mediates the relation between the organisational environment and job satisfaction, but not the relation between organisational commitment and the balance between professional and personal.

    Abstract: This study aims to explore the relationship between planned organisational change and organisational commitment-to-change and how would leader-member exchange moderates the relationship in regards to change readiness, valences and perception of change. Organisational change is a complex process and the behavioural responses of employees towards the change are rather complicated. Despite the complexity, not much research has been conducted to show how these variables are related to each other. One hundred eighty-four respondents from the financial industry of Malaysia had participated in this study. Based on the nature and characteristics of this research the SmartPLS method was used. Surprisingly, the results of planned organisational change and organisational commitment-to-change show different implications as compared to past research but leader-member exchange remains as the determinant in moderating the relationship between the two variables. In conclusion, the findings of this research create a new path for the study of an approach, unlike others.

    by Álvaro Dias, Veronica Silva, Leandro Pereira, Renato Lopes Da Costa, Rui Alexandre H. Gonçalves 
    Abstract: The present study aims to correlate the concepts of organisational environment and employee commitment, having the concept of transformational leadership, and its role in organisations and subordinates, as an interlinked chain. In the context of the organisational environment, it’s important that companies are aware that it is through transformational leadership, and greater attention to the needs of their employees, that they will be able to last through time, resisting constant changes, inside and outside the company organisational environment, and keep employees in the organisation. A good leader is essential in an organisation because it maintains the harmony between the human needs and the organisation objectives, perpetuating the culture of the organisation and thus promoting the growth and success of both the company and its constituents. Human development must be seen by organisations as an organisational strategy and people management is part of this process. The results have showed that organisational environment has a significant and positive effect on transformational leadership and that transformational leadership has a significant and positive effect on organisational commitment.

    by Mohammadjavad Nasiri Jahroudi, Mehdi Nani, Ebrahim Safa, Ehsan Sadeh 
    Abstract: In the present paper, an attempt has been made to identify the principles of the integrated project delivery (IPD) contract method, to assess the current status of infrastructure projects in developing countries to implement these principles. For this purpose, using a mixed method (qualitative and quantitative) and using interview tools and questionnaires, the opinions of experts in road construction projects in Iran were collected. The results of evaluating the current situation of these projects showed that in recent years, the application of participatory approaches, which is the beginning of IPD-based projects, is moving from the path of philosophy to the method of implementation. But there is still a long way to go to reach the end of the road, which is to complete projects with the IPD system. Also, based on the opinions of experts in examining the requirements and prerequisites for achieving the principles of IPD, various challenges were identified. Then, using integrated fuzzy multi-criteria decision-making methods (FAHP and FTOPSIS), these challenges were prioritised and corrective solutions for more important challenges were proposed.

    by Mahmoud Dehghan Nayeri, Moein Khazaei, Danial Abdolah Beiki 
    Abstract: This paper aims to identify the most affecting factors in the service industry’s new service development (NSD). Accordingly, it deploys an exploratory research method employing a rough set theory. To this aim, it assesses the NSD maturity level of 30 service firms in response to the extent of the literature-based NSD affecting factors. The NSD maturity was estimated according to Jin et al. (2014), including four areas of customer involvement, strategic, knowledge management, and required process documentation. Accordingly, the rough set approach employed to scrutinise the relationship between the affecting factors and the studied firms’ NSD maturity. Findings prove that innovation is the core of the NSD process since it was the most frequent within all RS reductions. Moreover, the organisation’s strategic orientation and maturity, and market orientation are the most significant determinants of firms’ future NSD potential.

  • Effect of uncertainty in demand and production for manufacturing industries during COVID-19   Order a copy of this article
    by Renu Sharma, Anubhav Pratap Singh, Ritu Arora, Anand Chauhan 
    Abstract: The demand for personal hygiene products has increased during COVID-19 pandemic outbreaks. It has resulted in the increasing production of hygiene products. During the corona virus epidemic, globalised and uncertain demand for personal hygiene products creates complicated situations for the manufacturing firms. This article explores the fuzzy model of economic production for hygiene products with uncertainty in demand and production. Due to the rising demand for hygiene products, the demand rate has set as a linear time function, while the production rate has been taken directly proportional to the rate of demand. Therefore, due to ambiguity or vagueness in demand, this proposed model has considered the triangular fuzzy number with an upper and lower split. The weighted sum method has turned the multi-objective problem into a single objective. The optimisation technique has used to minimise the producer’s overall cost under the condition mentioned earlier, and the model is validated numerically.

    Abstract: The purpose of the study is to examine the impact of downsizing on organisational performance. The study adopts serial mediation analysis through employee morale and tolerance to the ambiguity between downsizing and organisational performance. It uses organisational support theory to establish the relationship among study variables. The data are collected from employees in the manufacturing unit using a questionnaire and analysed using structural equation modelling. The analysis found that downsizing positively impacted organisational performance and provided evidence that downsizing action, when viewed as affirmative action by employees, brings positive outcomes. The results emphasised the importance of employee morale and the need to create a culture of tolerance to ambiguity for achieving sustainable organisational performance. The study results added to the downsizing literature by establishing both its direct effect and indirect effect on organisational performance.

    by Laurent Yacoub, Atef Harb 
    Abstract: Only 65% of restaurants survive beyond their fifth year, despite being a lucrative industry. Restaurant failure is prevalent in contemporary global business environments, including Lebanon. This study sought to explore external, internal, and personal factors that contributed to high closure rate of restaurants in Beirut despite its dining potential. A qualitative study using semi-structured interviews solicited owners’ perception of restaurant failure. Using snowball sampling, we interviewed 28 restaurateurs who ceased operation before their fifth year of operation. Findings found internal more than external factors accounted for restaurant failure, with personal factors playing a significant role. The research recommends restaurateurs focus on prudent financial management by investing more on professional development, human resource management and marketing, and technological aids, and less on aesthetic or high-end items at start-up that reduce return on investments. Moreover, owners should develop and implement pragmatic and consistent business strategies to improve brand positioning and operational coherence.

  • Optimization of a fuzzy inventory model with seasonal demand rate in two different markets   Order a copy of this article
    by Neelanjana Rajput, R.K. Pandey, Anand Chauhan 
    Abstract: The seasonal dependent demand is a major factor for the fluctuations in the demand for seasonal products. To fulfill this demand, the retailer produced a large size of items, but due to the short time of the season, there are some items remains in the stock. Due to the nature of the deterioration of the product, the retailer wants to sell all the products in stock. So the alternative marketing is the best way to get more profit with low inventory costs. The presented article is all about the fuzzy seasonal demand which depends on both price and time and retailers sell the products in both the potential markets say first and second. A second market is required to sell in good profit before all items go bad due to deterioration condition, but due to the different demand in both markets, the fluctuations comes in the demand. To deal with the vagueness of the demand parameter, we use a triangular fuzzy number and defuzzify with the signed-distance method to optimise the total profit function with a numerical example show the application of the model.
    Keywords: deterioration; Weibull distribution function; partial backorder; seasonal pattern demand; optional market; triangular fuzzy number; signed distance method.

    Abstract: The paper will explore the issue of the glass ceiling phenomenon that implies discriminatory actions toward women and minorities in the workplace. The invisible barrier prevents women and minorities from climbing above a certain level in the organisational chain of command. The purpose of the paper is to confirm the presence and identify the cause of the glass ceiling through an examination of its effects in the labour market. Hence, this is a comparative analysis paper of the glass ceiling phenomenon in the labour market in two different areas, the US and the EU. The historical literature selected indicates the constant progress of women and minorities in the middle management positions; however, little to no progress in the top management positions. The paper further explores possible explanations of the glass ceiling phenomenon such as personality difference, discrimination, and challenges of motherhood/childcare.

    by Zahra Namazian, Reza Kiani Mavi 
    Abstract: This paper proposes a bi-level, integer programming, and nonlinear model for the competitive location problems in the pharmaceutical supply chain. Existing and candidate distributors compete to successively service customers in competitive supply chain. It proposes a mathematical model for the Darou Pakhsh pharmaceutical supply chain where the upper level tries to propose the best locations for the distributors and the lower level selects the best distributors to cover the demand areas. The proposed mathematical model presents important factors such as the business share of the market and utility to optimise the competitive distributor location in the case study. Decision-makers are also interested in finding the rank list of distributors; therefore, the MADM method, VIKOR, is proposed to select the best distributors among different alternatives according to critical criteria. Finally, sensitivity analysis is used to analyse the effectiveness of the radius of influence of distributors parameters on the follower objective function.

    by Saheim Khalaf Al-Josaiman, Faisal Talib, Mohd. Nishat Faisal 
    Abstract: The research reported in this paper relates to the environmental dimension of sustainability in SCs in large manufacturing organisations in Qatar. Interpretive structural modelling (ISM) and cross-impact matrix multiplication applied to the classification (MICMAC) approach was applied to develop a hierarchy-based model for the 14 enablers of environmental sustainability derived through extensive literature review. Findings suggest that there is a set of variables like top management support and supportive legislation that can be considered as strategic in nature and drivers of environmental sustainability in SCs. While another set of variables like company image and reduced costs are resultant actions, which have high dependence implying that any improvement in these variables requires action on lower level variables. It is recommended that top management should focus on variables with high driving power and low dependence.

    Abstract: Due to the particularities of this business model and its recentness in emerging countries, the main purpose of this study is to analyse the antecedents that impact the consumers’ intention to use co-working spaces and their use behaviour among Brazilians who use shared workspaces. Considering this, we have adapted the unified theory of acceptance and use of technology 2 (UTAUT2) model by adding the motivational factors concerning the use of co-working space to increase the explanatory capacity of the model and find evidence on how to increase the attractiveness and effectiveness of this business. For this purpose, a survey with 259 users was conducted. Data analysis was performed with the Smart-PLS software, used for structural equations modelling (SEM). The main findings of this research indicate that performance expectancy, effort expectancy, social influence, hedonic motivation, habit, independence, work environment, and networking have a significant impact on the intention to use co-working spaces and the consumers’ use behaviour.

  • Robustness in Production Systems   Order a copy of this article
    by Christian Stockmann, Herwig Winkler 
    Abstract: In production systems, the concept of robustness is widespread due to various applications, purposes, and interpretations. However, little is known about the conceptual characteristics of robustness in production settings and even less about its distinctions from other related terms such as flexibility or agility. That is why this paper systematically reviews production literature to identify the contexts in which robustness is mostly applied and to analyse existing concepts. It is found that despite a vast literature body addressing robustness in varying forms, few studies cover it on a conceptual basis. Within this small sample, a rather general agreement on the meaning of robustness in production systems is found. However, details, interpretations, mentioned interlinkages to related terms differ across the identified literature. Based on the findings of the review and with the help of established literature on adjacent concepts, a comprehensive understanding of robustness in production systems is developed.

    by Sundus Chishti, Salma Ahmed 
    Abstract: The study reveals that how the interplay of human dimensions communication, collaboration, learning and trust helps in managing a green supply chain. The study is based on primary data as well as secondary data. Primary data was collected by interviewing supply chain experts in academia and industry. Secondary data has been collected from various case studies and surveys. The study revealed the importance of communication, collaboration, learning, and trust in managing a green supply chain. Communication coupled with collaboration imparts learning, skill development among supply chain members. Frequent communication among supply chain members and collaborative initiatives fosters the inter-organisational relationships which impart trust in the relationships. When the various firms trust each other, they work together towards a common goal that creates positive outcomes. Supply chain managers need to develop a long-term relationship with other stakeholders to manage a green supply chain.

    by Tesfaye Gashaw, Kassu Jilcha 
    Abstract: The purpose of this study is to conduct a systematic literature review of risk analysis techniques for railway construction projects. This review includes related papers on construction project risk analysis methods published between January 2000 and March 2020. For this review, the existing project risk analysis methods are classified as probabilistic, fuzzy logic, multi-criteria decision-making (MCDM) and system dynamics approaches. The results of the review showed that fuzzy analytic hierarchy process (FAHP) and fuzzy analytic network process (FANP) are dominant hybrid MCDM approaches for construction project risk assessment. Nonetheless, these approaches have their own limitations to handle dynamic and feedback effects of project risks as well as update new information when available. Hence, for railway construction project risk assessment, hybrid approaches that can deal with uncertainty, causal relationship, feedback, correlated and conflicting criteria are recommended for future research.

    Abstract: In this paper a novel perspective of lean application on the specific case of the oncology units was studied. The oncology department of a hospital located in the Southern Italy was investigated to find lean improvement solutions. In according with the well-known Lean philosophy, we have followed the DMAIC cycle (define measure analyse improve control). A discrete event simulator properly integrated with the value stream map tool, (hereinafter denoted as DVSM) was devised to improve the service level of the oncology department, under the objective of increasing the patients satisfaction. To this end, a design of experiments (DOE) involving several management factors has been developed and 72 future dynamic value stream maps (FDVSMs) have been evaluated accordingly. The ANOVA analysis allowed to statistically infer about the impact of all factors on the system and to identify the best FDVSM.

  • Supply Chain Considerations in Digital Strategies, E-Procurement, and CRM   Order a copy of this article
    by Alan D. Smith  
    Abstract: While supply chain disruptions are a drastic example of changes businesses must react to, being flexible and reactive will prove beneficial for companies. While being able to react to such disruptions is important, it is even more vital for supply chains to be proactive in a Covid-19 reality. Companies need to be adapting to changes in how customer relationships are maintained within digital supply chain (DSC) platforms. With more and more people working remotely, companies must still ensure their customer relationships are being maintained. This is one example of a supply chain challenge that this paper looks to unfold. By highlight the importance of digital platforms in e-procurement, increased technology and transparency are vital to successful companies, either B2C, B2B. Companies who are willing to learn and adapt become more competitive. The paper briefly dives into SAP Ariba and Jaggaer, and their role in aiding e-procurement and CRM.

  • Revisiting the global expansion strategy of fast-food brand: Modelling of satisfaction antecedents in marketing management   Order a copy of this article
    by Hiroko Oe, Max Weeks 
    Abstract: This study explores consumers’ perceptions of the fast-food business strategies of McDonald’s in a foreign market. Under the setting of Japan as a foreign market, a qualitative method is applied in the study, with 24 interviews with Japanese people based on the following key themes: local menu variations, local management and other employment opportunities, environmental friendliness, and corporate citizenship. It is found that Japanese consumers evaluate most the global brand value as an US icon in the Japanese market, rather than appreciating the effort in adapting to the local market. While it has typically been discussed that localisation is one of the key elements for business success, the outcome of this study suggests that research focusing on the antecedents realising customer satisfaction and loyal behaviour needs to have more attention, and that reconceptualising knowledge is important, especially since contradictory evidence appears as the global market expands.

  • Lean Operations and Competitive Advantage in the Pharmaceutical Industry   Order a copy of this article
    by Abdel-Aziz Sharabati 
    Abstract: The purpose of this research is to investigate the effect of lean operations on Jordanian pharmaceutical manufacturing (JPM) organisations’ competitive advantage. Data collected by a questionnaire from 116 managers working at 10 out of 14 JPM organisations. After confirming the validity and reliability of the questionnaire, the researcher conducted a correlation test between variables to check relationships, then multiple regressions to test the hypothesis. Results show that JPM organisations implement selective lean tools and competitive advantage dimensions. The research found that there is a strong relationship between lean tools, and between competitive advantage dimensions, as well as, between lean tools and competitive advantage. Regressions show that lean tools significantly affect cost, speed, and reliability, but do not significantly affect quality and innovation. Moreover, lead-time, setup time, inspection time, and delivery time significantly affect competitive advantage, while inventory does not significantly affect competitive advantage. The research recommends that carrying out similar studies to investigate the effect of lean tools on other industries in Jordan, and on the pharmaceutical industry in other counties to test results generalisability.

    by Akbar Hassanpoor, Saeed Jafarinia, Yousef Vakili, Seyyed Javad Marashi 
    Abstract: Organisational forgetting is the main issue in organisations that have been considered by researchers in recent years. This study was conducted to examine the causes and themes of organisational forgetting in organisations based on the thematic analysis. This paper’s case study comprised 40 Iranian and foreign studies on organisational forgetting over the past ten years. The results indicated that the main causes and themes creating organisational forgetting depend on two individual and organisational factors. In the case of individual factors, some components such as a sense of incapability and meaningless and organisational factors include organisational culture, inappropriate human resource management, lack of a strategic plan in the organisation, non-productive interactions in or out of the organisation, and lack of suitable maintenance and retrieval systems lead to such problem. According to the obtained results, it was recommended that researchers focus on designing an organisational culture model to cope with organisational forgetting by considering the mediating role of succession.

  • The Influence of DevOps Practices in ITSM Processes   Order a copy of this article
    by João Faustino, Ruben Pereira, Miguel Mira Da Silva 
    Abstract: In an information technology (IT) perspective, the world is evolving at a great speed. The IT services have expanded, most organisations started to implement processes that enable the lifecycle of these IT services. The discipline that covers all these processes is called IT service management (ITSM). Nevertheless, ITSM nowadays is seen as a bureaucratic discipline, where the process of creation and support of the IT services are two separate teams. There is an emerging agile culture called DevOps that aims to bridge these two teams: development and operations. The focus of this bridge into one team, is to deliver quality software and secure its operation. This research systematic analyses the literature and shed light on how DevOps practices can assist ITSM processes. This research concludes that automated deployment as the most useful practice and incident and problem management is the most beneficial processes. Future directions are pointed.

  • Linking Supply Chain Disruptions and Manufacturing Firms’ Operational Performance in a Developing Country Context   Order a copy of this article
    by ADENIKE MORADEYO, Adegoke Oke, Obinna Muogboh 
    Abstract: This study empirically investigates the link between supply chain disruptions and operational performance in manufacturing firms in a developing country context. Based on a survey sample of 150 manufacturing firms in Nigeria, hypotheses relating to the linkages between disruptions and firms’ performance were developed and tested. Multiple regression analysis was carried out using the data obtained from the survey. Four major categories of supply chain disruptions were identified and analysed: supply-related disruptions, demand-related disruptions, power-related disruptions and transportation-related disruptions. New categories of supply chain disruptions were identified in this context and are novel to risk categorisation in the main stream supply chain risk management literature. The study reveals further interesting and counter-intuitive findings in terms of the links between supply chain disruptions and manufacturing firms’ operational performance that may be unique to a developing country context. The theoretical and practical implications of the study were also discussed in this paper.

  • A Fuzzy inventory model for Gompertz deteriorating items with cubic demand and shortages under the fully backlogged condition   Order a copy of this article
    by K. Senbagam, M. Kokilamani 
    Abstract: This paper develops and resolves a fuzzy inventory model for the degradation of items with shortages in a completely back-ordered condition. The demand rate is assumed to be the cubic function of time. The rate of deterioration is considered to be the time distribution function of Gompertz. Fuzziness is carried out by allowing costs, costs of shortages, costs of deterioration, and parameters ?, ? to be maintained in the cost components. In a fuzzy world, all associated inventories are assumed to be hendecagonal fuzzy numbers. The objective of this paper is to optimise the overall profit from inventory optimisation by means of a graded mean integration representation and a signed distance method. The applicability of the proposed model is shown by a numerical example. The most important parameters of the device are often determined by a sensitivity analysis.

    Abstract: The current research study tries to find the impact of various demographic variables affects top management capabilities to define their role as leaders in the higher education sector of Khyber Pakhtunkhwa Pakistan. As the number of HEIs is increased, the role of their leaders also pivotal to get success for their organisations. For this purpose, data were collected from selected public and private sector universities situated in Peshawar to get detail about the leaders transactional and transformational capabilities and to align it with selected demographics. Based on findings, only two attributes contingent reward (CRD) attribute of transactional leadership and intrinsic motivation (INSTM) from transformational leadership depict a significant relationship between gender and leadership attributes. CRD is the primary attribute of leaders that differentiate both styles of leaders in university setup. Based on ANOVA results, it is evident that the education level of leaders does not make any sense to alter leaders capabilities. Similarly, the experience level of leaders alters their capabilities to infuse motivation among employees as well as to get the assigned job properly. While age shows a moderate relationship with both leadership (transformational and transactional) attributes.

    Abstract: One of the most significant aspects of quality in a project is the workmanship. Poor workmanship is one of the more crucial issues confronting local contractors in most developing countries and can also destroy projects already completed. Several studies have been conducted on factors contributing to poor workmanship and measures to mitigate the problem. A lack of experience, language barriers, lack of communication, unsuitable construction equipment, poor weather, and limited time and cost have been identified to be among the most notable contributors of poor workmanship. Regrettably, research conducted to date has focused inadequately on implementing and assessing alternative methods to improve workmanship performance. The study provides a critical assessment of researched literature to develop a conceptual integrated workmanship benchmarking framework and is expected to guide the development of a workmanship performance assessment tool and policy for the construction industry in Trinidad and Tobago.

  • Cancer-curing supply chain planning with regarding hospital bed-capacity efficiency: a plan for Iran in 2040   Order a copy of this article
    by Mina Haghshenas, Arash Nemati, Ebrahim Asadi Gangraj 
    Abstract: Nowadays, historical data show an increasing trend in cancer occurrence worldwide. Gathering all specialised cancer services in a cancer hospital increases cancer patients’ satisfaction by decreasing fatigue, stress, and time-wasting. This paper addresses the cancer hospital location-allocation problem as an important issue in cancer curing supply chain management. A mixed-integer linear mathematical model is developed to locate the cancer hospitals in candidate regions and allocate the cancer patients to proper destinations under bed-capacity efficiency consideration. The model minimises the total cost, including the cancer patients’ travelling cost, and the allocated bed-capacity providing cost. The cancer hospitals’ bed-capacity efficiency is mentioned as an important constraint of the model. The model is applied in the case of Iran in 2040. The cost parameters are calculated based on the time value of money concept. The annual cancer new cases in each province are forecasted by using simple linear regression models. Finally, 24 provinces are selected to construct at least one cancer hospital, and all cancer patients are allocated to them. The results can be used by Iran governmental healthcare authorities or private sector managers to do feasibility studies for cancer hospitals construction until 2040.

  • Designing an Optimal Plant Layout: A Case of the Plastic Molding Company   Order a copy of this article
    by Hokey Min, Seong-Jong Joo 
    Abstract: The generation of viable layout alternatives is a critical step in production planning since the chosen layout affects the efficiency of utilising the firm’s key resources such as space, equipment, materials, utility and workers. As such, it can dictate the firm’s productivity and the subsequent profitability. In addition, it can influence the safety and security of plants. Considering the important role of a plant layout in production planning, a small-to-medium enterprise (SME) that produces customised plastic moulding products begins to explore the better layout alternatives than the existing one that has become the sources of production bottlenecks, shipping delays, cycle counting errors and space crunches. Such alternatives include an L-shape, a straight line and a U-shape. To determine the optimal layout among three layout alternatives, we propose systematic decision-aid tools comprised of a mathematical model, computer-aided design (CAD), an activity relationship chart and a from-to-chart. We validated the usefulness and practicality of these hybrid tools for the plant layout by applying them to the real world problem encountering the plastic moulding company in the USA. Based on our proven success through the case study, other manufacturing firms can replicate the proposed tools for other layout challenges.

    by Faozi Almaqtari, Mohd Shamim, Anwar Ahmad 
    Abstract: The purpose of this study is to investigate the impact of corporate governance on starting a business in some Asian countries over a period from 2012 to 2017. Nine Asian countries on the basis of availability of data for the research period were selected for this study. Corporate governance is measured by the Worldwide Governance Indicators of the World Bank and starting a business is measured by the score of starting business reported by the Ease of Doing Business Report of the World Bank Group. The findings of the present study reveal that voice and accountability, political stability and absence of violence and regulatory quality have statistically significant effect on starting a business in the selected countries. While both political stability and absence of violence and regulatory quality are found to have statistical significant positive influence on starting a business, voice and accountability exhibits a significant negative effect on starting a business. However, the results reported that both government effectiveness and control of corruption exhibit an insignificant negative effect on starting a business, rule of law is found to have an insignificant positive impact on starting a business.

    by Alexandre Luis Prim, Juliano Danilo Spuldaro, Tiago Pedro Nicchellatti, Roberto Goularth Mendes 
    Abstract: Prior studies have highlighted several barriers to adopting emergent technologies; however, little is known about how collaboration mitigates those barriers and promotes new technologies. This study analyses the process of adoption of big data analytics (BDA) in a large cold-food distributor and the role of collaboration toward this progress. An inductive approach analyses a single case study. Concerned about reliability, a hundred and twenty hours of observation, six interviews with managers and consultants, and documents and reports of the company have been triangulated. Findings highlight a set of internal barriers (e.g., complexity, infrastructure readiness, lack of skills, privacy issues and cultural barriers), external pressure and collaborative efforts with an IT consulting group along with the BDA implementation. This study contributes to the literature by highlighting the collaboration with key partners as an asset that mitigates internal barriers and external pressures toward emergent technologies adoption. Finally, implementing a BDA solution can provide useful information for managers making decisions effectively, leading to improved processes, higher quality, reduced costs, and creating value for customers.

    by Garnov A. P, Abramov V. L., O.N. Bykova, Morkovkin D.E., Protsenko I. O. 
    Abstract: The interim analysis of the import substitution policy applied to the food industry shows that the food embargo policy is the key contributor to pursuing the targets. However, in addition to the positive results, the imposition of the food embargo also had such negative consequences as rising consumer prices. The authors use a system-functional approach, an abstract-logical method, a statistical-probabilistic method and a monographic study method in this paper. The analysis of the food industry market reveals a number of problematic issues that should be resolved in the coming years, such as the design of instruments to stimulate demand in the national and foreign markets, the export of domestic products to Asian markets, the solution of issues related to shipment and storage through the introduction of new logistics systems, solving the issues of staffing through the training of specialists who are versed in sanctions, possible restrictions and risks.

    by Maryam Dezhtaherian, Mahsa Ghandehari, Saeedeh Ketabi 
    Abstract: This paper considers a green inventory-routing problem (IRP) for perishable items in a two-level supply chain including a distributor (manufacturer/plant) and some retailers. Each item has a fixed expiry date. The product price depends on its age. The retailer demand for each product is fixed. The product cannot be sold after the expiry date. The possibility of hiring extra space for holding excessive amounts of inventory and hiring vehicles to exploit the advantage of the higher number of deliveries are considered. The problem is formulated to a mixed-integer linear programming (MILP) model. Some small, medium and large-sized random generated samples are solved using OPL software and a proposed combined ant-generic algorithm. The results show the positive effect of partial outsourcing on the amount of profit. Furthermore, the volume of orders is influenced by taking the environmental effects of transportation into account.

The relative efficiencies of these 18 terminals were analysed over a period of the last six years, starting from FY2013 to 2014 through FY2018 to 2019, by comparing the micro level factors contributing to the efficiency of ports. Data envelopment analysis (DEA) using Malmquist index was the methodology chosen for analysis. The study analysed the operational efficiency of the container terminals using a few factors like number of berths, depth of berths, quay cranes, goods handled in each terminal, the yard size of container terminal, the number of ships handled per container terminal, the workforce deployed at each container terminal, and the throughput of the terminals. The results exposed the fact that terminal efficiency was largely dependent on the technological changes.

    Abstract: This paper aims to develop an approach to improve the quality of the relationship between supplier and customer in the service process, disseminating the necessary information to translate the customer’s needs into quality requirements. The proposed approach uses the principles of the management excellence models, the ISO 9001:2015 certification and the quality function deployment tool. The customer service system (CSS) focuses on quality for service organisations. For this, the CSS adopts tools from the literature that are easy to apply, not requiring large investments from the organisation. This study contributes to organisations that intend to guide their management in a systemic methodology of adaptation to the requirements of the interaction between the supplier and the customer, since creating relationships with customers is a priority in several organisations. In addition, this approach aims to contribute to the literature and to the managerial decision-making process.

    by Mahdi Hamid, Shirin Ghasemi, Ahmad Ghasemkhani, Reza Ramezantabar 
    Abstract: Nowadays, customers form the basis of any business. Undoubtedly, they are the most significant factor in the stagnation or development of the economic status of any commercial unit. Therefore, anticipating and meeting their needs and improving the quality of services are the most essential duties of the managers. Customer relationship management (CRM) is a competitive advantage that deals with customers and their satisfaction. In this context, trust factors play a significant role in the fulfilment and improvement of CRM. Using factor analysis and data envelopment analysis for a real case study, this study aims to assess the effect of different trust factors (including moral behaviour, commitment, brand, usability, privacy and security, and competence) on CRM success. The results indicated that usability exerted the most effect on CRM, whereas privacy and security had the least effect. To date, this is the first research on the application and implementation of trust factors to promote CRM efficiency.

  • Extended-GS (E-GS) Optimum Solution for Multi-Criteria & Multi Alternative Problem   Order a copy of this article
    by Amal Alrasheed, Evon Abu-Taieh, Manal Al Ohali 
    Abstract: Decisions in this competitive and dynamic world must be correct, accurate, and objective. The process of deciding must be fast and precise. Since the dawn of technology, criteria and alternatives increased. Hence, tools, techniques, and methods were developed to conduct the process of decision making swiftly and correctly. Multi-criteria decision-making (MCDM) enhances the decision-making process by relying on calculated decisions rather than guessed decisions. Further, solving tools and techniques are perforated with gaps. To bridge such gaps between the tools and techniques, this paper suggests, Extended version of Gale-Shapley (E-GS) algorithm that utilizes three MCDM methods: Analytic Hierarchy Process (AHP), Weighted Product Model (WPM), and Weighted Sum Model (WSM). The basic idea of the E-GS algorithm is feeding the preference lists required by the Gale-Shapley algorithm to produce an optimum match using WSM, WPM, and AHP models. E-GS combined the powers of all four algorithms to provide an optimum solution.

  • Presenting a predictive benchmark model of after-sales service agencies for vehicles based on the Data Envelopment Analysis (DEA) Approach   Order a copy of this article
    by Sajjad Kheyri, Farhad Hosseinzadeh Lotfi, Esmael Najafi, Bijan Rahmani 
    Abstract: Everyone is aware of the importance of benchmarking in all industries. The same is true of the automotive industry. One of the methods of continuous improvement of car after-sales service agencies is benchmarking from successful and efficient examples in the country. Given that evaluation and benchmarking methods are usually retrospective, and also, the rapid changes in environment and customer needs, current methods cannot quickly define corrective actions. In this paper, first, a benchmarking model based on data envelopment analysis is developed for car after-sales service dealers as decision-making units, then considering that the model outputs have a high correlation coefficient, an innovative machine learning model has been used to predict the outputs. Finally, the results of the proposed prediction model are compared with a perceptron neural network algorithm. The results show that the benchmarking and prediction model together with a 7.7% error predicts benchmarks for the end of current period.

  • Redefining a Value Co-creation Behaviour Model for Student Satisfaction in HEIs   Order a copy of this article
    by Shamima Raihan Manzoor, Abdullah Al Mahmud 
    Abstract: The incorporation of customer relationships in marketing has triggered the paradigm shift from ´managing relationships ´to ´joint venturing ´ with customers. Thus, in the service sectors like higher education institutions (HEIs), students ´ active role has become prominent. This study explores the factors for establishing a consensual instrument to measure value co creation behaviour (VCcB) for HEIs and its impact on student satisfaction. The sample comprised 223 international students from Malaysian universities, both public and private. The factor analysis done with 29 items reveals four VCcB factors, out of which two (i.e., ´personal interaction, helping, and responsible behaviour ´, and ´information seeking and sharing ´) are found most influential in shaping VCcB for HEIs. By using PLS-SEM, the hypothesised relationships have been analysed for the VCcB factors ´ impact on students ´ satisfaction. The findings can inspire the HEI managers to build strong VCcB platforms to nurture student-university relationships as a part of their service marketing strategies

  • Identification of efficient production plans for a food packaging process using discrete event simulation   Order a copy of this article
    by Jenaro Nosedal-Sanchez, Carlos Rivera-Mejía, Javier García-Gutiérrez 
    Abstract: This paper addresses the problem of modelling and analysing the production capacity of a food packaging process. The model is formalised using coloured Petri nets and was implemented in CPNTools. The results reported correspond to the functional verification and the state space analysis of the model for determining the availability of each packing line and the overall availability of the system. The model allows obtaining measures such as the ratio between the production time and the time available for a specific period of production under different demand scenarios, determining the effect of a different assignment of the orders among the available packing lines. The results allow identification of work schedules for the best use of the packing lines capacity. The proposed framework is tested using a real case study, where a set of several feasible production plans are generated and the best course of action among these alternatives is identified.

  • Supplier’s performance evaluation in supply chains using item response theory   Order a copy of this article
    by Kathyana Vanessa Diniz Santos, Fernanda P. Arantes, Maria Silene Alexandre Leite, Antonio Cezar Bornia 
    Abstract: This study aims to propose a new methodology for supplier evaluation in supply chains. Using a questionnaire with 33 items that included five dimensions of supplier performance according to the literature (cost, time, quality, flexibility and innovation), it was possible to evaluate 243 supply links of 148 Brazilian companies. These results were evaluated using the IRT graded response model. IRT graded response model allowed a difficulty parameter to be established for each category of the presented items, defining performance levels in an interpretable scale that indicates the aspects served by each evaluated relationship. Depending on what the client company expects and prioritises in the performance of its suppliers, it can associate scale levels (and the presence and/or absence of certain aspects) with decisions about what to do in the relationship with the supplier company (e.g., strengthen relations, request changes in behaviour or terminate relationship).

  • Uncertainty, Responsiveness, and Operational Performance in Supply Chain: A Conceptual Study Using Contingency Theory Approach   Order a copy of this article
    by Jitendra Nenavani, Rajesh Jain 
    Abstract: Amid uncertainty from customers and suppliers, academicians and practitioners have focused on building a supply chain that is robust enough to withstand the disruption damages. Given the several supply chain risk mitigation strategies like flexibilities, agility and postponement, this is the first such paper to analyse the relationship between supply chain responsiveness and supply chain uncertainty through contingency theory lenses. To arrive at a conceptual framework that aims to build the relationship among the constructs, this study in detail has studied the literature of selected articles on supply chain uncertainty from peer-reviewed journals. Findings not only draw attention to the role of responsiveness in the supply chain under uncertainty but also indicate towards analysing the effect of the relationship between uncertainty and performance. Therefore, we believe that supply chain responsiveness, being a mediator in the framework presented, might lessen the impact of supply chain uncertainty on operational performance.

    by Amar Kumar Mishra, Sulagna Das, Som Nath Paul 
    Abstract: Non-performing asset has been a big issue in the banking sector since long. Though in the recent years the rate has gone down due to the recovery and other measures adopted by the Government of India. The present paper studies the non-performing assets of the public sector banks, private sector banks and scheduled commercial banks, arising in both priority and non-priority sectors in India. The paper is divided into three parts. The first part observes the trend of non-performing assets occurring in the priority and non-priority sector, in case of the three bank groups. Second part analyses if there is any difference in the gross non-performing asset occurrence pattern between and within the bank groups, for priority sector and non-priority sector lending. Third part of the paper analyses if there is any impact of the gross non-performing asset on the gross advances in priority sector and non-priority sector.

    by Anastasios Tsogkas, Giannis T. Tsoulfas, Panos T. Chountalas 
    Abstract: Designing, implementing, and supporting a radical organisational transformation project in an environment of relatively low technological and managerial capacities, and under strict human resource and time constraints is both challenging and unique. The purpose of this paper is to present such a case of a public sector organisation in the course of implementing a business process reengineering (BPR) project. The findings of this study reveal that in cases where public sector operational and supply chain activities share a high degree of similarity with private sector commercial activities, BPR is the most appropriate methodology to be used to fundamentally revise and redesign processes and achieve radical improvements. BPR can effectively enforce industry standards with no need to envision and design new processes from scratch, as long as compliance is ensured with laws, legal acts, and ministerial decisions governing public sector entities’ operational procedures.

    by Shihhao Liu, Chin-Hsiang Tsai 
    Abstract: This study develops service quality attributes for ski group package tours (SGPTs) based on the SERVQUAL scale; it explores the perceived importance and performance of these items for SGPT customers in Taiwan. A questionnaire was used to collect data from 456 respondents. This study used importance-performance analysis (IPA) to analyse SGPTs’ service quality and employed impact-asymmetric analysis to compensate for the shortcomings of the original IPA by estimating the asymmetric effect of service quality attributes on overall customer satisfaction. Subsequently, five service quality attributes of SGPT were extracted. IPA was also conducted for each gender and ski level segment. The results indicate that the perceived importance and performance of service quality attributes differ significantly among different market segments.

  • Examining trade-offs in the airline industry   Order a copy of this article
    by Alka Nand, Prakash J. Singh, Ananya Bhattacharya 
    Abstract: Firms develop and manage their operational capabilities to improve efficiency and competitive positioning. However, as the theory of performance frontiers (TPF) suggests, there are limits to these gains. As firms become more efficient, they are likely to be trading off capabilities rather than pursuing them simultaneously. A key question that arises is whether these trade-offs are beneficial for firms. In this paper, we apply the TPF to firms in the airline industry. Specifically, we address whether a firm’s efficiency levels are associated with trade-offs and if level of efficiency subsequently affects the firm’s market success. We employed the data envelopment analysis (DEA) methodology to analyse operational capabilities and determine the efficiency of all airlines operating domestically in Australia over a ten-year period. The results show broad support for TPF. Firms that demonstrated efficiencies were trading off capabilities with associated market success.

    by Suchita Lokhande, Avinash D. Sarode 
    Abstract: In manufacturing sector, the medium scale industries play an important role for the Indian economy. There is a drastic change in customer demands posing a major challenge before the manufacturing industries. Agile manufacturing (AM) is a concept which incorporates customer issues in the traditional manufacturing process, lack of awareness about the use of AM needs the proper identification of enablers considering Indian scenario. Agility is the amalgamation of technology and management which is useful in the manufacturing sector, thus the use of scalable framework and integrated computer manufacturing is the need of an hour. Medium scale industries are not aware about AM; however, it will be appropriate if the Indian manufacturing industry also makes use of AM. For the implementation of AM in the Indian manufacturing industry, the most essential enablers are identified in this paper. A phase wise literature survey spanning from year 1995 to 2020; divided in three phases of seven, seven and nine year respectively, provided the focus on the enablers. From the in-depth literature review of 167 papers and discussion with experts, we have 85 sub-criteria with 12 categories of enablers.

    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.

    by Zaheer Abbas, Abd Rahman Bin Ahmad, Muhammad Saeed Shahbaz, Muhammad Mujtaba Asad 
    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 principal 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 have been adopted. The reviewed literature revealed that the government provides performance based grants to the public sector universities so government have pursued 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.

    Abstract: Multidisciplinary research is a practical approach to address one of the most important global challenges, that is shortage of resources. 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.
    Keywords: energy; generation; sustainability; attitudinal loyalty; behavioural loyalty; green buildings.

  • The impact of institute size on the relationship between technological, organisational factors and ERP usage: a moderation analysis of Indian higher educational institutes   Order a copy of this article
    by Pratima N. Dabholkar, Hema Date 
    Abstract: The purpose of the study is to test the moderating effect of size of the institute on ERP usage in Indian higher educational institutes. Technological factors and organisational factors have direct influence on ERP usage. Multiple group modelling was used to determine whether or not the grouping variable, institute's size, has any influence on the structural equation model for the observed variables. There is a void in literature to see the moderating effect of size of the higher educational institutes on ERP success. The key finding of the study proved that size of the higher educational institutes moderates the relationship between technological factors, organisational factors and ERP usage which creates value for the institute. The model can be used as a guideline to ensure a positive outcome from ERP implementation in higher educational institutes. It also provides relevant recommendations to address issues related to ERP success in higher educational institutes.
    Keywords: enterprise resource planning; ERP; technological factors; organisational factors; multiple group models; higher educational institute's size.

  • A dynamic literature review on 'lean and agile' supply chain integration using bibliometric tools   Order a copy of this article
    by Ibrahim Oluwole 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.
    Keywords: lean; agile; leagile; supply chain; literature review; systematic literature network analysis; SLNA.
