A coordination mechanism through value-added profit distribution in a supply chain considering corporate social responsibility

The consumers pay more and more attention to corporate social responsibility (CSR), which has been a new competitiveness for the enterprises. This paper constructs a supply chain consisting of a dominated retailer, a socially responsible supplier and a non-socially responsible supplier (compared with the socially responsible supplier), consider the consumer preference and exploit the game analysis technique to analyze the optimal decisions under the decentralized and concentrated decision, and then design a coordination mechanism based on value-added profit distribution. The results show that compared with the decentralized decision, the retail price and order quantity of two products are lower, the CSR effort degree of socially responsible supplier is higher, and the performance of the whole supply chain is better under the concentrated decision. In addition, the mechanism designed can induce the socially responsible supplier to undertake CSR without damaging its profit, prompt the supply chain members to make the concentrated decisions, and promote the competitiveness of the retailer-dominated supply chain.     

Integrating sustainability and resilience in the supply chain: A systematic literature review and a research agenda

Sustainability has emerged as an important industrial strategic outlook expanding beyond organizational boundaries to include the supply chain. Simultaneously, the industry has also been faced with supply chain resilience concerns. Research on the intersection of supply chain sustainability and resilience is nascent and is a consequence of their observed mutual influences. However, confusion about concepts, implementation methods, and measurements of sustainable and resilient supply chains remains. This study completes a systematic literature review that critically examines several major observations and directions. We find the concept of sustainable supply chains is more established, and general agreement on its theoretical foundations exists. Supply chain resilience is relatively less mature. The nexus and relationships between the two topics are often incoherent: there is confusion on sustainable and resilient supply chains establishment; there is no clarity on what practices could jointly advance both areas. A major conflict exists since sustainability generally focuses on efficiency, while resilience seeks effectiveness. We recommend studies to analyze implementation relationships and impact. We also observe that performance measurement systems should be developed to assess supply chain sustainability and resilience performance taking with explicit consideration time horizons considered in these measures.

Two-period supply chain coordination strategies with ambidextrous sustainable innovations

This study considers a manufacturer with ambidextrous sustainable innovation capability selling products in environmentally conscious market through an independent retailer in a two-period game setting. We design a two-period game theoretic and dyadic supply chain (SC) model considering exploitative and exploratory nature of environmental innovations. We study five different contract types, namely, wholesale price contract, vertical Nash game structure, cost sharing contract, revenue sharing contract and two-part tariff contract. We demonstrate the impact of market sensitivity towards sustainable innovation and cost parameters on optimal level of decision parameters. The equilibrium results reveal that a suitably designed two-part tariff contract can be used to achieve coordination in a fragmented SC. The equilibrium results assist managers to optimise the SC based on the two-period contract model. The results obtained in this study can help the decision-makers to take decisions on investment in the ambidextrous sustainable innovation under different types of contract structures.

A model of integrated regional logistics hub in supply chain

ABSTRACT

A regional logistics hub is a constellation of multiple logistics facilities in a region of several provinces or states. This research models an integrated regional logistics hub with consideration of time-phased demand in a multi-echelon, multi-period, and capacitated logistics network. The integrated logistics hub considers three phases based on the characteristics of China’s five-year planning policy. By applying mixed integer linear programming, the greedy heuristics approach, the particle swarm optimization algorithm, and the Hungarian method, the location of logistics facilities at different echelons of a supply chain is identified and the needs for facility expansion or closing during different time periods are determined.

The sustainable humanitarian supply chain design: agility,adaptability and alignment

The sustainable humanitarian supply chain (SHSC) has been the subject of research and debate over recent years. The aim of the paper is to provide an SHSC definition, propose an SHSC structure and validate it empirically. A unique contribution of the present study is an attempt to delineate humanitarian supply chain (HSC) management from commercial supply chain management and further discuss the HSC from the point of view of sustainability. We identify three important characteristics of a HSC network: agility, adaptability and alignment, and further explore possible linkages using extant literature and interpretive structural modelling (ISM). We further test the constructs using confirmatory factor analysis. In this way we attempt to answer long-pending calls from past researchers to contribute to the existing theories of HSC and identify further research directions based on the limitations of the present study.     

Gaining from disorder: Making the case for antifragility in purchasing and supply chain management

The purchasing and supply chain management (P&SCM) discipline assumes that supply chains are fragile systems, hence taking a “negative” approach toward disorder. Building on Taleb’s concept of antifragility—the ability to gain from disorder rather than avoiding it—, we challenge this traditional assumption. The COVID-19 pandemic has revealed that some companies were indeed able to gain from disorder, whereas some of those that focused too much on robustness and resilience lost ground. Building robust and resilient supply chains may no longer be enough to thrive in today’s highly volatile business world. This article sparks a new debate by introducing antifragility to the P&SCM literature and provides new directions for future research.     

Using integrated information systems in supply chain management

The aim of this paper is to empirically test not only the direct effects of information and communication technology (ICT) capabilities and integrated information systems (IS) on firm performance, but also the moderating role of IS integration along the supply chain in the relationship between ICT external and capabilities and business performance. Data collected from 102 large Iberian firms from Spain and Portugal are used to test the research model. The hierarchical multiple regression analysis is employed to test the direct effects and the moderating relationships proposed. Results show that external and internal ICT capabilities are important drivers of firm performance, while merely having integrated IS do not lead to better firm performance. In addition, a moderating effect of IS integration in the relationship between ICT capabilities and business performance is found, although this integration only contributes to firm performance when it is directed to connect with suppliers or customers rather than when integrating the whole supply chain.     

Uniting partners to cope with environmental uncertainty: Disentangling the role of social capital in developing supply chain agility

Based on social capital theory, in this study, we investigate how a firm utilized social capital to coordinate partners in the achievement of supply chain agility under different levels of environmental uncertainty. We test the proposed hypotheses via a hierarchical regression analysis using questionnaire survey data collected from 190 firms in China. The empirical results show that cognitive, relational, and structural capital positively influence supply chain agility. Furthermore, environmental uncertainty positively moderates the positive relationship between relational capital and supply chain agility, whereas environmental uncertainty negatively moderates the positive roles of cognitive and structural capital. The findings suggest managers should adopt different strategies when leveraging social capital according to the business environment. In unpredictable and volatile business environments, managers should motivate their firms to embrace relational capital to obtain sufficient resources for achieving supply chain agility.     

Inclusive purchasing and supply chain resilience capabilities: Lessons for social sustainability

In the face of unexpected changes in their dynamic business environment, purchasing and supply chain (SC) managers have been challenged to boost SC resilience while maintaining their sustainability concerns. In this changing environment, this paper aims to explore: (1) how (social) sustainability affects SC resilience and (2) what the role of purchasing is for SC resilience. Through a dynamic capability view as the theoretical lens, we investigate whether and how an inclusive purchasing programme could enhance SC resilience capabilities to cope with the Covid-19 outbreak. We developed a Case study with various SC members of a multinational cosmetics company that, despite suffering from a sudden demand disruption during the outbreak, maintained its sustainability actions. The results show that four operational SC resilience capabilities were amplified: ‘visibility’, ‘adaptability’, ‘collaboration’ and ‘financial strength’. In addition, a new capability entitled ‘empowerment’ was mobilised during this period. These factors helped the inclusive purchasing maintenance and were essential to supporting social sustainability. In addition, our results show that sustainable PSM, which is overlooked in the literature, is key for SC resilience. This article contributes to theory and practice because it demonstrates the role and relevance of (inclusive) purchasing in a company's ability to cope with SC disruptions, such as those resulting from the outbreak.     

Sustainable supply chain management in tourism

Sustainable supply chain management (SSCM) encapsulates the trend to use purchasing policies and practices to facilitate sustainable development at the tourist destination. Most research has focused on environmental aspects of manufacturing, while other aspects of sustainability or the challenges for the service sector are largely ignored. Yet SSCM is particularly important for tour operators, as the product depends on the activities of suppliers, such as accommodation, transport and activities. Therefore, tour operators' contribution to sustainable tourism will be more effective through the definition and implementation of policies that acknowledge responsibility for the impacts of suppliers. Exploratory research of SSCM practices amongst tour operators generated a wide range of examples of good practice across the whole supply chain, and recommendations are made for more widespread engagement.

Assessment of CSR based supply chain performance system using an integrated fuzzy AHP-TOPSIS approach

The objective of this research was to identify Corporate Social Responsibility (CSR) criteria as well as propose and prioritise the alternatives to improve the supply chain performance system of an organisation. To meet the objective, firstly, CSR-based criteria, sub-criteria and alternatives were identified based on the literature review and discussion with the field experts, taken from automobile industries located at the Delhi region of India. Then, kappa statistics has been applied to check the internal consistency between identified criteria and sub-criteria. After finding the evidence of internal consistency, a hierarchical-type model has been developed and analysed using a multi-criteria decision-making as an integrated fuzzy analytical hierarchy process (AHP) and a fuzzy technique for order performance by similarity to the ideal solution (TOPSIS) approach. To make the results more robust and feasible, a sensitivity analysis has also been performed.

Managing supply chain resilience to pursue business and environmental strategies

Resilience has become a crucial topic in the field of strategic management as it requires companies to design resilient business models to tackle managerial and environmental disruptions of individual firms and supply chains. However, extant research still lacks deep insights into how companies design and manage supply chains according to the resilience principles. With this premise, this paper aims at conducting a state of the art review on supply chain resilience (SCR) considering 125 relevant papers collected from Scopus and Web of Science academic search engine. Starting from the results of the literature review, this study proposes a systemic framework of SCR assessment and contributes to improve the understanding of the impact of different empirically tested constructs on the development of the resilience concept. Further, the findings are summarized in several areas including barriers in developing resilience, metrics to measure the resilience performance, and effective strategies to foster the SCR. Finally, this study outlines promising future research directions for scholars and practitioners.     

Supply chain decisions and coordination in the presence of an imperfect spot market

This study considers a supply chain consisting of a commodity supplier and a final product manufacturer with uncertain demand. In addition to purchasing from the supplier through a forward contract, the manufacturer can adjust their inventory by trading the commodity in an online spot market after observing the actual demand. However, the spot market is imperfect in that transactions cannot be certainly realized and come with additional transaction costs. Furthermore, the spot price is volatile such that overly relying on the spot market is unwise. To investigate how the spot market affects the decisions and coordination in a supply chain, we develop a game-theoretical model incorporating spot trading. We derive the optimal ordering decision in a centralized supply chain, as well as the supplier's and manufacturer's equilibrium pricing and ordering decisions in a decentralized supply chain. The impact of the imperfect spot market on the optimal decisions and profits is analyzed. This study also demonstrates how the supply chain can be coordinated in the presence of an imperfect spot market. Finally, a numerical analysis is performed to examine the analytical results. Our results indicate that the spot market can generally improve the performance of the centralized supply chain and benefit the manufacturer in the decentralized one. However, it can be detrimental to the supplier. The supply chain can be coordinated by a revenue-sharing contract, and both parties' profits can be improved. Our findings suggest that the manufacturer could take advantage of the spot market, and the supplier should attempt to integrate or coordinate the supply chain to share the benefits of spot trading.     

Green supply chain management in the automotive industry: A study in Brazil

The auto industry is experiencing a time of restlessness, which stems from several elements that currently threaten the stability and status quo of its supply chains. Among these elements are autonomous driving, connectivity, electrification, and trip sharing that has led to new forms of mobility. In this context, this article presents the results of a research, which had three main objectives: (1) to identify the green supply chain management (GSCM) practices most commonly implemented in all industrial sectors worldwide, (2) to evaluate how these practices are considered by professionals in the automotive industry and by researchers working on the subject in Brazil, and (3) to identify and evaluate which practices are most widely adopted within these companies and/or supply chains and influence their environmental performance. The research method combined a qualitative research step (Delphi) with another quantitative one (survey). The results show that most of the reality of the automotive industry in Brazil is in line with studies on GSCM practices worldwide, but some specific findings have also been identified and discussed.
