Creating world-class supply chains

This article will share knowledge in two areas: The elements of world-class supply chains and the linking processes from customers' customers to suppliers' suppliers and the management approaches needed to engage the people and the organization in an effective implementation process to achieve world-class status.     

Perspectives on risk management in supply chains

Managing risk in supply chains is an important topic in supply chain management. The topic's importance is due to several industry trends currently in place: increase in strategic outsourcing by firms, globalizations of markets, increasing reliance on suppliers for specialized capabilities and innovation, reliance on supply networks for competitive advantage, and emergence of information technologies that make it possible to control and coordinate extended supply chains. This article identifies some important aspects of risk management in supply chains and summarizes the four articles that are in this special issue. This emerging area of research interest deserves considerable attention and it is our hope that the articles in this special issue would spur additional research on this important topic.     

Sustainable supply chains: An introduction

Consideration is given to the convergence of supply chains and sustainability. In doing so, the focus on environmental management and operations is moved from local optimization of environmental factors to consideration of the entire supply chain during the production, consumption, customer service and post-disposal disposition of products. This is a critical and timely topic that captures increasing concerns over sustainability, whether driven by current legislation, public interest, or competitive opportunity. As such, sustainable development is a rich area for academic research that is still in its infancy and has the potential to affect future government policy, current production operations, and identify new business models. This paper provides a background to better understand current trends in this multidisciplinary field that intersect with operations management, and the research opportunities and challenges it presents.     

Government subsidy provision in biomass energy supply chains

ABSTRACT

This paper investigates the government’s optimal subsidy provision strategy for a biomass energy supply chain that consists of the power plant, the villagers’ committee and farmer. We examine three possible subsidy provision strategies depending on which party (the power plant, the villagers’ committee or the farmer) the government chooses to subsidise, and compare how it can influence the government’s target by assuming that the subsidy price is exogenously given. We also extend our findings when the government can endogenously determine the subsidy price. Moreover, our analyses reveal the optimal stakeholder selection strategy for each party to maximise its payoff.     

Proactive planning for catastrophic events in supply chains

Supply chains are increasingly vulnerable to catastrophic events such as hurricanes or terrorist attacks. This is not only true because firms are more exposed to catastrophes, but also the result of investments made in recent years to operate supply chains with fewer human and capital resources, especially inventory. Consequently, there is today less “slack” available in supply chains to deal with catastrophic events. Thus, proactively planning for these types of events should be a priority for supply chain managers. A catastrophic event has a very low probability of occurrence but has significant consequences if it does occur. The goal of this research is to develop a process to proactively plan for catastrophic risk events through an integration of diverse research streams related to the management of risk. In particular, the proposed process builds upon an existing risk analysis framework by incorporating an innovative methodology used by the insurance industry to quantify the risk of multiple types of catastrophic events on key supply chain locations.     

The effects of bargaining power on trade credit in a supply network

We develop a multi-tier supply network model, rooted in social network theory, to evaluate the effect of bargaining power on trade credit and to track the effect of buyers' trade credit on suppliers' trade credit. We apply social network analysis to measure companies' bargaining power in the supply network of Hennes & Mauritz AB (H&M, the Swedish clothing retailer). The results show that the buyer's bargaining power significantly affects the choice of trade credit, and that the supplier's “upstreamness” is significantly associated with its trade credit. We find limited evidence to support the notion of a financial bullwhip effect, a result that merits further research, since this study is limited to the network of one company up to its fourth tier of suppliers in one financial year. Our results can be applied by companies seeking to control their cash flow and, therefore, the financial pressure within their supply network. This study contributes to the literature by bringing social network measures into the buyer–supplier financial flow, as well as offering one of the first empirical examinations of the propagation of financial pressure in a multi-tier supply network.     

Market competition and pricing strategies in retail supply chains

This study provides a better explanation for the continued prevalence of high–low (Hi–Lo) pricing strategy. We investigate the impact of market competition on adopting two different pricing strategies in the retail industry: everyday low price (EDLP) strategy and Hi–Lo strategy. We developed two analytic models using a game-theoretic modeling approach: the profit maximization model and the sales revenue maximization model. We then conducted an econometric analysis based on retail store-level dataset. The result shows that an EDLP player's equilibrium price depends highly on the cost level rather than competitor's price whereas the Hi–Lo player's equilibrium price depends mainly on the range of promotional basket as well as the cost level.     

Antecedents of supply chain visibility in retail supply chains: A resource-based theory perspective

Although visibility has become a popular buzzword in the supply chain literature it remains an ill-defined and poorly understood concept. It is assumed that if companies across supply chains have visibility of demand, inventory levels, processes, etc., that organizational performance improves. This research explores the antecedents of high levels of supply chain visibility from a resource-based theory perspective across five different external supply chain linkages. We find that the level of visibility across these linkages differs considerably based on various contributing factors which are both technology and non-technology based. Using resource-based theory, we identify those factors that can give a sustainable competitive advantage to a supply chain linkage through a “distinctive” or high level of visibility.     

The frontiers of eBusiness technology and supply chains

This article is an Introduction to this Special Issue on “eBusiness and Supply Chain Management.” It also provides a vision for eBusiness and supply chain for the future.     

Theoretical perspectives on the coordination of supply chains

Supply-chain coordination relies on the availability of prompt and accurate information that is visible to all actors in the supply chain. However, new demands on the supply-chain system require changes to information flow and exchange. We undertake a case study of three automotive supply chains that face such new demands resulting from the introduction of an order-driven supply-chain strategy. We use our case study findings to evaluate the applicability of three different theoretical lenses on the multi-faceted interactions between information, physical flow, and the complex rationales driving supply-chain evolution: the resource-based view (RBV), the concept of complex adaptive systems (CAS), and adaptive structuration theory (AST). We find that each theory has a separate realm of applicability and while complimentary in nature, provides distinct insight on the structural shift in the supply-chain system. More specifically, we find that AST, a theory prominent in the social sciences, provides novel insights to supply-chain research at the firm level, particularly with respect to the difficulties in using IT systems to drive systemic change. It complements both the system-level perspective offered by the complex adaptive systems theory, as well as the concept of dynamic capabilities originating in the resourced-based view. The paper concludes with wider implications for future research in supply and value chain management.     

Optimal strategic alliance in multi-echelon supply chains with open innovation

We propose a game-theoretic approach to examine several possible coalition strategies in a four-echelon supply chain consisting of a supplier, manufacturer, wholesaler, and retailer. A solitude model is used to probe the role of learning in quality improvements, and experimental design is conducted to evaluate all possible supply chain coalition strategies between echelons. The novelty of this study is the comprehensive evaluation of knowledge-sharing strategies in collaborative supply chains. The results confirm that the Delta model with a coalition among a supplier, manufacturer, and retailer is the best strategy.     

Investigating the value of information sharing in multi-echelon supply chains

Under the structure of multiple business entities, supply chain management (SCM) offers the external and internal integration of business processes in enterprises. The most important objective of SCM is to enhance the supply chain performance such as reinforcing the service level and increasing profit as well as reducing order cycle time and inventory. In recent years, due to the advancement of information technology, enterprises can manage the product flow and the information flow via economical and efficient mechanisms. The well-organized information sharing can enhance the supply chain performance and allow enterprises to refine their strategies of supply chain in order to maximize their profits. The previous studies pointed out the positive effect of information sharing on the efficiency of supply chain. However, relatively little literature focuses on the performance analysis for multi-echelon supply chain with various information sharing scenarios. By using the simulation technique, this paper models different scenarios of information sharing, and further analyzes the impacts of information quality on multi-echelon supply chain performance. In addition, this paper employs Data Envelopment Analysis (DEA) to integrate multiple performance measures to ensure the information sharing scenarios with enhanced performance.     

Contrasting FOR and WITH factor chains: The case of material supply chains and human factor chains in Guatemalan nongovernmental organizations

Nongovernmental organizations (NGOs) have varied success in meeting the challenges of disasters in Antigua, Guatemala. This research uses the TO–FOR–WITH model based on nine criteria that separate surviving NGOs from transient NGOs. Two Guatemalan NGOs, Corazon de los Nino and Sonidos para la Vida, are used to validate the model. The two NGOs differ on three of the nine criteria in the TO–FOR–WITH model. Corazon meets all nine criteria and is considered a WITH organization using local sources for employment, supplies, and logistics. Sonidos is a FOR organization because it falls short in the three categories of bilateral communication, residual intelligence, and post hoc deployment. The criteria were found to distinguish the two NGOs in meaningful ways. However, two cases are not sufficient for theory building. We distinguish between factor chains and material supply chains, a distinction that is especially salient for humanitarian services, which are the primary offerings of many NGOs. No prior studies have tested this recent model and no previous studies have addressed the distinction between material supply chains and factor chains. Additional research is needed including expanding to other NGOs, other countries, and other settings.     

Practices and strategies for sustainability-related risk management in multi-tier supply chains

This study investigates how sustainability-related risks are managed in multi-tier supply chains. It focuses on the strategies and practices that companies use to manage sustainability-related risks and how these differ between supply chains and supply chain tiers. We use a multiple-case study with 25 companies forming 5 multi-tier supply chains. As a result of this study, we present a conceptual framework for sustainability-related risk management practices in multi-tier supply chains and apply it empirically by defining sustainability-related risk management profiles for the case supply chains. We show that in multi-tier supply chains, companies need direct and indirect collaboration and direct and indirect monitoring practices for managing sustainability-related risks emanating from not only their first-tier suppliers but also lower-tier suppliers. Our framework helps purchasing and supply chain managers understand the dimensions of sustainability-related risk management in a multi-tier setting and develop strategies and practices for mitigating and managing those risks. We also empirically show the challenge of extending sustainability-related risk management practices beyond first-tier suppliers due to the different practices in different supply chain tiers.     

Sustainable reverse supply chains and circular economy in multichannel retail returns

The percentage of products being returned in multichannel retail are high and further increasing, yet many retailers and manufacturers are unaware of the importance and scale of this issue. They consider dealing with returns as a cost of doing business and are oblivious of the potential for conflicts between their corporate social responsibility commitments and their returns practices. This article investigates how far sustainable practices and circular economy concepts have been implemented in retail returns systems; it identifies vulnerabilities, barriers, and challenges to the implementation of sustainable, circular practices and suggests ways to overcome them, as sustainability, loss prevention, and profit optimisation can go hand in hand with the right approach to the organisation of the reverse supply chain. Implications of this research on strategic management are outlined. The research was conducted using in‐depth interviews and observations with four major retailers in the United Kingdom, 17 structured interviews, 100 retailer website reviews, and three retail community workshops, all with British and other European retailers.     

Valuing time in supply chains: Establishing limits of time-based competition

Over the past two decades the growth in international trade and the offshore migration of US manufacturing have created global supply chains with longer lead-times and slower response. This suggests that traditional supply chains have encountered limits to time-based competition in which the cost of faster replenishment exceeds the benefits. This paper explores and quantifies those limits to time-based competition in make-to-stock supply chains for functional products (products with stable demand over relatively long life cycles).     

The selection of contracts in supply chains: An empirical analysis

This paper seeks to empirically identify the key drivers for firms in selecting a contract in a supply chain by investigating their performance, supply chain orientation, and supply chain integration. A conceptual model is drawn up based on the existing literature in supply chain coordination contracts, performance, supply chain orientation, and supply chain integration and tested on a large sample of European firms. Multiple and multinomial logistic regression models allow for estimating the relationships between these variables. Our results demonstrate that the selection of contracts and the probability of their adoption depend on several combinations of firms' performance, supply chain orientation, and integration. Overall, the research provides an empirical contribution to the literature on coordination with contracts, which turns out to be mainly game theory based.

A reference architecture for IoT-based logistic information systems in agri-food supply chains

ABSTRACT

Logistics in the food and agribusiness industry must address perishable products, unpredictable supply variations and stringent food safety and sustainability requirements. The Internet of Things (IoT) could contribute significantly to solve these challenges because it allows for remotely controlling the location and conditions of shipments and products. This paper develops a reference architecture for IoT-based logistic information systems in agri-food supply chains. It proposes a hybrid solution that combines the IoT and cloud computing. The architecture supports the provision of affordable tailor-made solutions by utilising technology enablers of the European Future Internet programme and by facilitating the reuse of domain-specific functionalities.     

Cooperation strategies in port-oriented bulk supply chains: aligning concept and practice

It seems intuitively obvious that firms in supply chains may have more to gain than to lose from learning to cooperate; but it is now more than two decades since Poirier [1999. Advanced Supply Chain Management. San Francisco, CA: Barrett-Koehler] and others called for cooperation in order to capture mutual gains in supply networks and even now ‘cooperation is neither common nor easy’. The simple fact is that not only are supply chains exceptionally complex but so too is the ‘process of cooperating’ – often in the context of antitrust legislation and competition policy. This paper argues that there is a critical need to rethink the principles and processes of cooperation within the broader framework of the competitive behaviour of firms and business strategy. Particularly, it suggests that the relatively recent thinking of Greenwald and Kahn [2005 Greenwald, B., and J. Kahn. 2005. Competition Demystified A Radically Simplified Approach to Business Strategy. New York, NY: Portfolio, The Penguin Group. [Google Scholar]. Competition Demystified A Radically Simplified Approach to Business Strategy. New York, NY: Portfolio, The Penguin Group] in their ‘radically simplified approach to business strategy’ offers sound conceptual insights into cooperation and cooperative strategies for firms not only in markets but also in chains. Furthermore, it notes that the analytical framework for cooperation and cooperative strategies which the authors develop is far removed from the notion of cooperation as ‘commitment and trust and shared thinking’ and from ‘buyer/seller reciprocity’ and ‘collaborative attitudes’ which tend to underwrite much contemporary thinking and research. The paper also argues that the Greenwald and Kahn framework – its single intelligence model of cooperation and cooperative strategies – resonates with real-world relevance, at least for particular supply chains. The paper focuses attention on research into globally significant export coal chains from major east coast Australian ports and in brief case studies finds substantial alignment between concept and practice.
