This model investigates the variable production cost for a production house; under a two-echelon supply chain management where a single vendor and multi-retailers are involved. This production system goes through a long run system and generates an out-of-control state due to different issues and produces defective items. This model considers the reduction of the defective rate and setup cost through investment. A discrete investment for setup cost reduction and a continuous investment is considered to reduce the defective rate and to increase the quality of products. Setup and processing time are dependent on lead time in this model. The model is solved analytically to find the optimal values of the production rate, safety factors, optimum quantity, lead time length, investment for setup cost reduction, and the probability of the production process going out-of-control. An efficient algorithm is constructed to find the optimal solution numerically and sensitivity analysis is given to show the impact of different parameters. A case study and different cases are also given to validate the model.

The management of a controllable production in the manufacturing system is essential to achieve viable advantages, particularly during emergency conditions. Disasters, either man-made or natural, affect production and supply chains negatively with perilous effects. On the other hand, flexibility and resilience to manage the perpetuated risks in a manufacturing system are vital for achieving a controllable production rate. Still, these performances are strongly dependent on the multi-criteria decision making in the working environment with the policies launched during the crisis. Undoubtedly, health stability in a society generates ripple effects in the supply chain due to high demand fluctuation, likewise due to the Coronavirus disease-2019 (COVID-19) pandemic. Incorporation of dependent demand factors to manage the risk from uncertainty during this pandemic has been a challenge to achieve a viable profit for the supply chain partners. A non-linear supply chain management model is developed with a controllable production rate to provide an economic benefit to the manufacturing firm in terms of the optimized total cost of production and to deal with the different situations under variable demand. The costs in the model are set as fuzzy to cope up with the uncertain conditions created by lasting pandemic. A numerical experiment is performed by utilizing the data set of the multi-stage manufacturing firm. The optimal results provide support for the industrial managers based on the proactive plan by the optimal utilization of the resources and controllable production rate to cope with the emergencies in a pandemic.

The paper analyzes the advantages of using the blockchain technology in the supply chain management. It is determined that the blockchain will simplify the procedure of the government control over the supply chain and contribute to the implementation of the state policy aiming to reduce the level of counterfeit products and improve the quality of goods entering the retail network, which will have a direct impact on the socio-economic development of the regions. The subject of research is the organizational and technological mechanism of the interaction between business entities in the process of introduction and application of the blockchain technology for supply chain management. The purpose of the paper was to find out how to use the blockchain in logistics in the most effective way. The paper presents the summary of works of Russian and foreign economists and identifies the main areas of existing and prospective blockchain studies, formulates the principles for the promotion of the blockchain technology in logistics and identifies factors that impede the active use of the blockchaining by Russian and foreign businessmen. The necessity of the DLT/blockchain legalization in economic activities and determining the responsibility for including incomplete and/or unreliable information in a distributed ledger is substantiated.

In recent years, the European hospital sector has suffered the brunt of the economic crisis. This sector is now faced with a paradox, which is to reduce costs, related to the decline in government subsidies and an increase in the quality of care required by the regulatory bodies, while maintaining the level of care. This paradox can be resolved through the optimization of the hospital supply chain. Despite hospital supply chains having a great impact on hospital budgets, many opportunities for optimization exist to improve the healthcare quality. This chapter aims to analyze the distribution of drugs within a hospital in the line of supply chain management. The SCOR model was selected as the framework for this analysis. Then, potential failures that can arise in logistics processes are identified. After reviewing the literature regarding the hospital supply chain and the performance measurement, a framework is proposed with key performance indicators that can be applied in hospital supply chains to measure and monitor their performance.

The supply system in health sector determines effective stock management, regular material supply, speed, and quality of maintenance and service process. Elimination of all non-value-adding activities, movements, and processes in the procurement process; minimizing errors; and increasing the efficiency of the process between the inputs and outputs of the hospital is possible by applying total quality in supply management. Effective supply chain management in health institutions improves the quality of healthcare.

This article is focused on a sub domain of quality, namely, quality of service. Considering supply chain management, the authors believe that it is important to distinguish between a quality of product (also service) offered by producers and service providers and a quality of service which is achieved between any supplier and customer, not only a consumer, along a supply chain. Quality of product represents producer’s/service provider’s commitment and is subject of various quality certificates issued by inspection authorities. This research examines the quality of service, which is provided by a supplier to its customer along the supply chain, between any pair of chain elements fulfilling this relation, including the common retailer-consumer relation. The authors introduce measurement points into a consumer-centric supply chain model for the defined criteria and defined the method of their monitoring and overall supply chain quality of service evaluation. Finally, the authors assess the envisaged impact of the results of their measurements on supply chain excellence, providing management with an opportunity to identify weak spots.

The agricultural supply chain consists of many participants like producer (generally farmer), consumer (people who buy the product and consume them), wholesalers, and retailers. This system consists of many levels of mediator parties as well which have different policies of the commission. Due to the difference in these policies, the producers do not get their fair share of price. Due to the varying prices, consumers also suffer as they do not get the right quality of the product for the right price. There are no central records maintained regarding the transactions between the participants which could lead to many serious problems. To tackle the above-mentioned issues, we need a holistic approach that can provide solutions to most of the above issues. Here, blockchain-based solution can be used to achieve traceability (we can trace the whereabouts of the product, the origin of the product, etc.), transparency (so that a sense of trust is achieved), fairness (by removing the intermediaries), assurance of food safety and pricing (so that nobody has to bear the loss).

Purpose This study aims to examine publications of supply chain management (SCM) researchers from across the world and maps the leadership role of authors and institutions based on how prolific they are in publishing and on network measures of centrality while accounting for the quality of the outlets that they publish in. It aims to inform stakeholders on who the leading SCM scholars are, their primary areas of SCM research, their publication profiles and the nature of their networks. It also identifies and informs on the leading SCM research institutions of the world and where leadership in specific areas of SCM research is emerging from. Design/methodology/approach Based on SCM papers appearing in a set of seven leading journals over the 15-year period of 2001-2015, publication scores and social network analysis measures of total degree centrality and Bonacich power centrality are used to identify the highest ranked agents in SCM research overall, as well as in some specific areas of SCM research. Social network analysis is also used to examine the nature and scope of the networks of the ranked agents and where leadership in SCM research is emerging from. Findings Authors and institutions from the USA and UK are found to dominate much of the rankings in SCM research both by publication score and social network analysis measures of centrality. In examining the networks of the very top authors and institutions of the world, their networks are found to be more inward-looking (country-centric) than outward-looking (globally dispersed). Further, researchers in Europe and Asia alike are found to exhibit significant continental inclinations in their network formations with researchers in Europe displaying greater propensity to collaborate with their European-based counterparts and researchers in Asia with their Asian-based counterparts. Also, from among the journals, Supply Chain Management: An International Journal is found to exhibit a far more expansive global reach than any of the other journals. Research limitations/implications The journal set used in this study, though representative of high-quality SCM research outlets, is not exhaustive of all potential outlets that publish SCM research. Further, the measure of quality that this study assigns to the various publications is based solely on a publication score that accounts for the quality of the journals, as rated by Association of Business Schools that the papers appear in and nothing else. Practical implications By informing the community of stakeholders of SCM research about the top-ranked SCM authors, institutions and countries of the world, the nature of their networks, as well as what the primary areas of SCM research of the leading authors in the world are, this research provides stakeholders, including managers, researchers and students, information that is helpful to them not only because of the insights it provides but also for the gauging of potential for embedding themselves in specific networks, engaging in collaborative research with the leading agents or pursuing educational opportunities with them. Originality/value This research is the first of its kind to identify and rank the top SCM authors and institutions from across the world using a representative set of seven leading SCM and primary OM journals based on publication scores and social network measures of centrality. The research is also the first of its kind to identify and rank the top authors and institutions within specific areas of SCM research and to identify future research opportunities relating to aspects of collaboration and networking in research endeavors.
