Understanding the dynamics of global supply chain sustainability initiatives: The role of institutional distance from the buyer's perspective

Research points to sustainable supply chain management as a core strategic goal for most global firms. However, managers continue to struggle with implementing successful sustainability initiatives both internally and throughout their globally dispersed supply chains. Using grounded theory, our findings uncover a potential explanation for how firms manage sustainability initiatives in the context of global supply chain management, from a buyer's perspective. Institutional theory of the firm is applied to help explain the challenges of developing and implementing global supply chain sustainability-related initiatives within buyer-supplier relationships. Analysis of the data from qualitative interviews show that institutional distance is an influential factor that produces mixed effects on the global buyer-supplier relationships in our sample in the context of buyer and supplier strategic orientation toward sustainability. The findings can help guide managers when approaching sustainability-related initiatives in the context of global supply chains. Theoretical and managerial implications are discussed as well as areas for future research.     

Supplier development and cost management in Southeast Asia—Results from a field study

This paper is about supplier development when international companies have production sites in Southeast Asia and look for opportunities to switch from international suppliers to local suppliers. We conducted a field study involving site visits to companies in Thailand and Vietnam, and interviews at corporate supply chain departments. Some key observations are: cost management was a dominant motive for taking local supplier development initiatives. Furthermore, local sourcing and local supplier development were important for international companies to improve access to local customer markets. Firms deliberately assessed whether a particular supplier would likely be able to improve sufficiently to warrant investing in supplier development, which typically involved a combination of initiatives, requiring the international firm to take considerable efforts. Local sourcing strategies and priorities for supplier development initiatives tended to focus on items with low supply risk and low volume. These findings are discussed based on transaction cost economics, and we suggest that firms use several ways to reduce the risk of transaction-specific investments in supplier development initiatives.     

Joint decision of procurement lot-size,supplier selection,and carrier selection

The joint decision making of procurement lot-size, supplier selection, and carrier selection has potential to reduce buyer's purchasing expenditures. Furthermore, the total logistics cost can also come down through economies of scale in the purchasing and transportation costs, and reduction in supply chain disruptions such as rejections and late deliveries. We study a procurement setting in which a buyer needs to purchase a single product from a set of suppliers over finite discrete time periods to satisfy service level requirements. The suppliers offer all-unit quantity discounts, and transportation cost depends on carrier capacity as well as geographical location of suppliers. This paper proposes an integer linear programming model to simultaneously determine the timings of procurement, lot-sizes, suppliers and carriers to be chosen so as to incur the least total cost over the planning horizon. A numerical example is included to demonstrate the effectiveness of the proposed model in establishing tradeoffs among purchasing cost, transaction cost, and inventory holding cost. Sensitivity analysis has been carried out to understand the effects of the model parameters on the purchasing decisions and total cost. Managerial insights of this study serve as a reference for decision makers to develop effective procurement strategies.     

The role of intermediaries in establishing a sustainable supply chain

In sustainable supply chain management, buyers may use intermediaries to bridge exchanges with suppliers when knowledge of suitable sustainability practices is weak and in need of facilitation. Understanding how supply chain intermediaries perform this role and what happens when intermediation is no longer needed is important in establishing more sustainable supply chains. Two supply chain intermediaries have been investigated with the resulting case study evidence analysed using the Gioia methodology. The findings suggest supply chain intermediaries add value to the buyer-supplier exchange by facilitating sustainability-related information transfer, knowledge development, risk management and improved capabilities. For example, specific practices such as corrective action reports, often managed by the intermediary, underpin the development of a sustainable supply chain. When the intermediary is no longer needed, they become disintermediated from the specific buyer-supplier exchange but may be re-employed in a new triadic relationship in the future with previous parties. This provides positive spill-over effects through intermediation–disintermediation–post-intermediation cycles for both the buyer and supplier populations and for broader society. Overall, the findings highlight the value of the transient position of supply chain intermediaries in establishing sustainable supply chains and the intended consequences of their involvement.     

Supplier Development Practices for Sustainability: A Multi‐Stakeholder Perspective

Supplier development for sustainability is a critical element of sustainable supply chain management and requires extensive multi‐stakeholder collaboration. This article establishes a conceptual four‐stage framework to analyse the collaborative mechanisms of supplier development practices, and presents an exploratory, qualitative analysis to identify the major contributors of sustainable supplier development practices, such as NGOs, industrial associations, consulting firms etc. Based on semi‐structured interviews about 63 organizations from different regions and industries, this article identifies three types of contributor: drivers, facilitators and inspectors. Instead of traditional stakeholder engagement processes, these contributors actively collaborate with buying firms and suppliers to design, implement and evaluate sustainable supplier development programs. The article then provides a matrix to describe the supply chain coverage and supplier performance of supplier development practices, given the absence or positive involvement of facilitators and inspectors. We conclude our study by suggesting future research directions as well as discussing managerial implications. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment     

Framing Sustainable Supply Chain Finance: how can supply chain sustainability practices and supply chain finance solutions be integrated?

Supply chain finance (SCF) can play a role in improving supply chain (SC) sustainability. That is why academics have started investigating the connection between SCF and sustainable SC management, and practitioners have begun developing new SCF solutions with a sustainable orientation. Although SCF solutions have been suggested as supporting tools for the diffusion of sustainability within SCs, academic contributions have only partially investigated sustainable SCF (SSCF). There is the need to understand in greater detail first, how different SC sustainability practices (e.g., supplier assessment, supplier development, incentives to suppliers, and third-party involvement) can be integrated into SCF solutions; second, how different brokerage roles can facilitate this integration to contribute to the successful implementation of an SSCF solution. This paper investigates those aspects through multiple international exploratory case studies. The results confirm that SCF solutions become sustainable by integrating different SC sustainability practices, either embedded in the SSCF solutions or reinforced by the implementation of the solutions. Moreover, involving new actors, including third-party information providers, NGOs, and certification bodies, who assume different brokerage roles, positively influences the development of SSCF solutions.     

How Does Sustainable Development of Supply Chains Make Firms Lean,Green and Profitable? A Resource Orchestration Perspective

This paper theorizes and tests the effects of sustainable development of supply chains on cost‐reduction (lean), environmental (green) and financial (profitable) performance. Based on the resource orchestration theory, we argue that internal, supplier and customer sustainable development each orchestrate different types of resource and therefore their effects vary. Structural equation modeling of data from a survey of 203 Thai manufacturers was used to test a new theoretical model. Results confirm that financial performance was achieved through cost reduction created by customer sustainable development supported by internal and supplier sustainable development. On the other hand, better environmental performance created by internal sustainable development generated no financial gains. However, internal, supplier and customer sustainable development positively affected each other, and by acting together they made firms lean, green and profitable.

Core issues in sustainable supply chain management – a Delphi study

Sustainable supply chain management has emerged as a growing topic, receiving increasing interest in the sustainability and supply chain management area. So far, the field is dominated by either case or survey based research. Few attempts have been made to take a broader look at the overarching issues, which form core topics of sustainable supply chain management. This paper presents the findings from a Delphi study where experts were asked to contribute their opinion. The Delphi study allows an aggregation of these opinions and extracts underlying topics in a structured manner. Four major topics were identified, which are (1) pressures and incentives for sustainable supply chain management, (2) identifying and measuring impacts on sustainable supply chain management, (3) supplier management (particularly addressing issues at the supplier–buyer interface) and (4) supply chain management (dealing with issues across all companies involved in the supply chain). The research presented contributes to substantiating and consolidating the field of sustainable supply chain management. Copyright © 2007 John Wiley & Sons, Ltd and ERP Environment.     

Supply chain decisions under asymmetric information with cost and fairness concern

ABSTRACT

The two-echelon supply chain including single supplier and single retailer is set, and we study the compact of asymmetric information on the decisions in the supply chain when the both supplier’s private cost information and retailer’s private fairness-concern information are asymmetry between the supply chain members, so as to study the effect of misreporting behavior and fairness concern on the supply chain. By mathematical model derivation and numerical analysis, we prove that the misreporting behavior of supplier will intensify the unfair distribution of supply chain and thus make the supply chain operation further deviate from the optimal condition.     

Incenting managers toward the triple bottom line: An agency and social norm perspective

Research to date has identified CEO pay structure as an important factor in the environmental and social performance of the organization but has not considered how pay may influence these sustainability efforts at the middle‐management level. We address this void with an experimental manipulation of direct and indirect pay incentives for an environmental sustainability project and production cost savings project. Counter to our predictions, investment in sustainability versus cost savings is significantly lower when incentives for both projects are equivalent, and investment is only comparable when incentives for the sustainability project are superior. Further investigation using qualitative data attributes this to differences in the salient social norms that individuals hold and an apparent undervaluing of the indirect incentive derived through sustainability's contribution to cost savings. The results shed light on primary ways in which human resource management practices may be used to embed support for sustainability initiatives throughout the organization.     

Sustainable development in the craft brewing industry: A case study of Iowa brewers

The rapid expansion of the resource-intensive brewing industry has led to U.S. and state-level initiatives to encourage sustainable craft brewing practices. These efforts raise questions about brewers' current brewing practices and the conditions and factors that might influence a brewer's decision to adopt sustainable practices. We conducted an in-depth survey of Iowa craft brewers in 2019 to evaluate current sustainability practices within breweries. In addition, we elicited brewer perceptions regarding consumer preferences and willingness-to-pay for sustainably produced beer. We analyze these factors together with data on brewery production characteristics and the brewer's personal beliefs and demographics. While most breweries in our sample track key environmental metrics to some degree, many of them lack environmental plans. Further, we find significant variation in the degree to which brewers believe there is opportunity to leverage sustainable brewing practices to charge consumers a higher price. We also provide insight on relationships between environmental practices and potential resources provided to breweries. These findings improve our understanding of craft brewers' tradeoffs regarding sustainable brewing practices that could apply more generally to other resource-intensive sectors.     

Participation of suppliers in greening supply chains: An empirical analysis of German automotive suppliers

The public increasingly holds companies accountable for environmental misbehavior in their supply chains. To offset that risk corporations start initiatives to green their supply chains. Yet suppliers often fail to properly participate in these initiatives. This paper presents a conceptual framework to explain supplier participation in green initiatives, by investigating customer requirements, supplier readiness, relational norms and customer investment as possible drivers. The framework and hypotheses were tested using survey data of 54 German automotive suppliers. Partial least squares methodology was deployed for hypothesis testing. The study found supplier readiness and customer requirements to be significant drivers in supplier participation. Relational norms and customer investment did not per se yield significant importance for explaining supplier participation, but when taking into account firm size, the data suggests that cooperative relation norms and customer investment work as an additional driver in green supply chain management for larger suppliers. This research is one of the few studies that explore drivers for supply chain participation at the supplier's level.     

Global supplier selection using fuzzy analytic hierarchy process and fuzzy goal programming

Global supplier selection is a multi-goal multi-criteria problem which needs to consider both qualitative and quantitative factors. Which suppliers are the best and how much should be purchased from the selected suppliers is an important purchasing issue for manufacturers. Traditionally, decision makers can determine the best supplier from evaluating few suppliers with qualitative supplier selection criteria by using fuzzy analytic hierarchy process (FAHP), but evaluate dozens of global suppliers simultaneously or determine the order quantity from them will be complex and difficult. Meanwhile, decision makers can determine the order quantity form the suitable suppliers by using fuzzy goal programming (FGP); however, it is not easy to decide weights for each goal of global supplier selection with different supply chain strategies. This study integrated the FAHP and FGP (FAHP-FGP) method to be a new approach for global supplier selection in considering the manufacturer’s supply chain strategies. With FAHP-FGP method, the manufacturer can consistently integrate multi-manager’ opinions in determining weights of each goal and obtain the order quantities for suitable suppliers based on manufacturer’s strategies. To demonstrate the usefulness of the proposed method, a real-world case of a digital consumer products manufacturer is presented.     

Structural model for analysis of key performance indicators for sustainable manufacturer–supplier collaboration: A grey-decision-making trial and evaluation laboratory-based approach

With growing competition in the market and dire need for sustainability, it has become imperative for companies to build long-term relationship with their supply chain partners through sustainable collaboration. Among these, the supplier–manufacturer relationship is crucial for improved organizational, business and sustainable performance. Sustainable collaboration with suppliers involves crucial decision-making processes such as continuous supplier monitoring and supplier development. Hence, a critical challenge that a company faces is to identify the key performance indicators (KPIs) for assessing the performance of a supplier for sustainable collaboration. In this regard, this study focuses on identification of KPIs for an Indian home appliance company through exhaustive discussions involving multiple decision-makers. Further, a grey-based decision-making trial and evaluation laboratory (DEMATEL) model is proposed in the study for analysing the importance levels among the fifteen KPIs based on multiple stakeholder perspectives. The results of the grey structural model indicate seven KPIs as influencing KPIs and eight KPIs as influenced KPIs. The KPI ‘Information disclosure’ has been identified as the most influential KPI for the evaluation of suppliers for sustainable collaboration. The implications drawn from the result analysis model can provide meaningful insights to managers for identifying strategies towards strengthening the supplier–manufacturer relationship and achieving organizational and market competence.     

Impact of relational norms, supplier development and trust on supplier performance

Supplier relationship management and supplier development initiatives assume a fundamental role in enterprise supply chain management. An important aspect of effective supplier relationship management is the role of trust. This paper seeks to understand whether supplier relationship management or supplier development initiative should be emphasized as a firm strives to achieve superior supplier performance. The analysis and discussion draws upon sourcing strategy literature and is based on empirical survey-data of mid to upper level managers with responsibility for supply management initiatives in their respective organizations in Denmark and in the USA. It examines the interrelationships among “relational norms”, “trust”, “supplier development initiatives” and ensuing “supplier performance”. The data analysis shows that firms must emphasize relation and trust building activities before investing in supplier development initiative. Supplier perception audits must be routinely performed to gauge the level of trust and strength of relational norms.     

Making sustainable sourcing decisions: practical evidence from the automotive industry

Achieving environmental and sustainable performance within an organisation’s supply chain and manufacturing operations will be feasible if upstream supply partners have the same commitments in performing their operations in a sustainable manner. Given the debate above, we propose a comprehensive framework to address the sustainable supplier selection and order allocation (SSS&OA) problem. The framework developed is practical, that starts by using an audition check-list specific for each sustainability dimension (environmental, economic and social), from which the weighted values of its comprised criteria are obtained. The weighted scores of the selected sustainable suppliers are utilised by a proposed bi-objective order allocation model in order to make sourcing decisions. The strength of the proposed framework is its practical applicability to provide a solution for SSS&OA problems which is validated through a real-world application. Finally, research findings, theoretical and managerial insights and also directions for additional research are presented.     

The role of supply management innovativeness and supplier orientation in firms’ sustainability performance

Questions about the influencing factors and measurement of firms' sustainability performance have attracted growing research interest, as the requirements for sustainability have steadily increased. This study examines whether supply management innovativeness and supplier orientation make positive impacts on firms' overall sustainability performance. An empirical study based on a survey targeting large- and medium-sized manufacturing companies in Finland shows that innovativeness in supply management considerably influences a firm's overall sustainability performance and that supplier orientation positively relates to sustainability performance. The benefits of innovativeness in supply management and strategic supplier orientation are directly realised in sustainability performance. Therefore, supply management is not only a gatekeeper against sustainability risks arising from the supply base but is also a function by which new ideas aiming to influence supply markets and firms' sustainability are presented.

Public procurement for innovation through supplier firms' sustainability lens: A systematic review and research agenda

Public sector purchasing processes are gaining increasing prominence as a demand-side innovation tool for addressing national sustainability challenges. Accordingly, there has been growing research attention to this topic. Prior studies suggest three key rationales that underlie the use of public sector procurement to drive innovation: (i) the buyer–user rationale (for creating new needs); (ii) the market/system failure rationale (for improving suppliers' capacity to innovate); and (iii) the public services rationale (for improving public services). However, operational activities at the upstream supply chain affecting the sustainable innovation capacities of supplier firms appear to be under-researched in the public procurement for innovation (PPI) scholarship, despite knowledge about innovation capacity being critical to successfully implementing PPI. This paper adopts a systematic literature review approach to synthesise existing fragmented literature on sustainability-oriented PPI, focusing on supplier perspectives. Findings from a synthesis of 41 relevant articles suggest, among others conditions, that a procurement framework that maintains a good balance of competition and innovation, builds buyer–supplier relationship and urges strong supply networks, maintains a stable political commitment, offers security for niche markets with effective innovation risk management culture would enhance suppliers' sustainability capacity and propensity to innovate. This paper contributes to the PPI literature and the literature on determinants of sustainable innovation systems from supplier firms' sustainability lens.     

供应不确定下基于Supply-hub的供应商选择和库存协同决策

针对由供应商、Supply-hub和制造商组成的三级供应链的多产品供应商选择和库存协同问题,考虑供应商存在延迟交付风险、供应数量约束,以供应链运作成本最小为目标,构建整数规划模型。分析结果表明:在一定的条件下,总存在最优的供应商选择方案和库存策略;当供应商的延迟交付概率增加,供应链期望成本上涨;当供应商供应数量无限制时,减少最优订货批量可以弱化供应不确定性增加造成的影响;当供应商选择方案不变,订货提前期增加,供应链的运作成本以及最优订货批量不变;一种零部件提前期的变化不影响其他零部件的供应商选择和库存策略。
