Decision Support For Lead Time And Demand Variability Reduction, Xin Fang, Cheng Zhang, David J. Robb, Joseph D. Blackburn

Research Collection Lee Kong Chian School Of Business

Companies undertaking operations improvement in supply chains face many alternatives. This work seeks to assist practitioners to prioritize improvement actions by developing analytical expressions for the marginal values of three parameters – (i) lead time mean, (ii) lead time variance, and (iii) demand variance – which measure the marginal cost of an incremental change in a parameter. The relative effectiveness of reducing lead time mean versus lead time variance is captured by the ratio of the marginal value of lead time mean to that of lead time variance. We find that this ratio strongly depends on whether the lead time …

Where Next For Supply Chain Management?, Des Lee

Books/Book chapters

Supply chain management (SCM) has been so successful that it is largely taken for granted. Its success has been built on improving three key flows – of product, of money and of information – and on one core principle – core competence. What next for SCM? This article outlines the vulnerabilities that are embedded in modern supply chains and the unintended consequences of outsourcing activities that are not core competences. These consequences are global and have the potential to undermine past achievements. Finally, broad suggestions are made as to how these issues can be addressed and the areas on which …

Fairness-Trust-Loyalty Relationship Under Varying Conditions Of Supplier-Buyer Interdependence, Thani Jambulingam, Ravi Kathuria, John R. Nevin

Business Faculty Articles and Research

Relationship marketing plays a significant role in supply chain practice and academic studies. Using the resource advantage theory within the relationship marketing framework, we studied the mediating role of trust as a governance mechanism in the fairness-loyalty relationship under different types of interdependence structure between suppliers (wholesalers) and buyers (retailers). Our findings, based on data from retail pharmacies, demonstrate that only under conditions of symmetric independence, trust, as a governance mechanism, completely mediate the relationship between fairness and loyalty. Under conditions of both perceived independence (i.e., lack of interdependence) and asymmetric buyer dependence, however, trust does not mediate but fairness …

Supply Chain Integration: Cluster Analysis Of The Impact Of Span Of Integration, Vijay R. Kannan, Keah Choon Tan

Management Faculty Publications

Purpose

This paper aims to explore whether firms that integrate only with partners adjacent to them in the supply chain exhibit different patterns of supply chain practice and performance than those that also integrate with partners more distant in the supply chain.

Design/methodology/approach

Cluster analysis of survey data is used to partition firms based on the span of the supply chain involved in their integration efforts.

Findings

Firms with a broad span of integration have a greater focus on alignment with suppliers and customers, and have more of a supply chain focus than those with a narrow span. They also …

Supply Chain Information And Relational Alignments: Mediators Of Edi On Firm Performance, Keah Choon Tan, Vijay R. Kannan, Chin-Chun Hsu, G. Keong Leong

Management Faculty Publications

Purpose: The purpose of this paper is to examine the effects of inter-organization information exchange on supply chain information and relational alignment. Drawing on literature on information systems, supply chain management, and logistics, the paper aims to present a multidimensional framework for considering electronic data interchange (EDI) adoption in supplier management and its effect on information and relational alignment. Design/methodology/approach: Theories drawn from resource-dependent and transaction cost economics, and the resource-based view of the firm were used to establish hypotheses. Structural equation modeling using survey data of manufacturing firms was used to test the hypotheses and research model. Findings: Results …

Information Sharing And Strategic Signaling In Supply Chains, Robert J. Kauffman, Hamid Mohtadi

Research Collection School Of Computing and Information Systems

Information sharing in procurement occurs in rich and varied industry contexts in which managerial decisions are made and organizational strategy is formulated. We explore how information sharing ought to work in procurement contexts that involve investments in inter-organizational information systems (IOS) and collaborative planning, forecasting and replenishment (CPFR) practices. How and under what circumstances does a firm that plays the role of a supply chain buyer decide to share information on key variables, such as point-of-sale consumer demand data with its supplier, up the supply chain? This is a key issue that crosses the boundary between supply chain management and …

Supply Chain Management Practices As A Mediator Of The Relationship Between Operations Capability And Firm Performance, Chinchun Hsu, Keah Choon Tan, Vijay R. Kannan, G. Keong Leong

Management Faculty Publications

The current study uses mediated regression analysis and structural equation modeling to test the proposition that supply chain management practices mediate the relationship between operations capability and firm performance. Operations capability is defined in terms of a firm's new product design and development, total quality management and just-in-time capabilities. Results support the research model and also suggest the existence of a direct relationship between operations capability and performance.

Antecedents Of Supply Chain Visibility In Retail Supply Chains: A Resource-Based Theory Perspective, Mark Barratt, Adegoke Oke

Management Faculty Research and Publications

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 …

Is Lean Necessarily Green?, Kumar Venkat, Wayne Wakeland

Systems Science Faculty Publications and Presentations

This paper investigates the environmental performance of lean supply chains using carbon dioxide emissions as the key performance indicator. Lean is based on the premise that compressing time reveals hidden quality problems and that their resolution leads to more efficient, cost-effective business processes. If time compression always implies lower emissions, then a leaner system is always greener as measured by emissions. If time compression does not always lead to lower emissions, then further changes to the lean system may be required in order to make it greener. We use a simulation model of a generic supply chain as well as …

Closed-Loop Supply Chain Models With Product Remanufacturing, R. Canan Savaskan, Shantanu Bhattacharya, Luk N. Van Wassenhove

Research Collection Lee Kong Chian School Of Business

The importance of remanufacturing used products into new ones has been widely recognized in the literature and in practice. In this paper, we address the problem of choosing the appropriate reverse channel structure for the collection of used products from customers. Specifically, we consider a manufacturer who has three options for collecting such products: (1) she can collect them herself directly from the customers, (2) she can provide suitable incentives to an existing retailer (who already has a distribution channel) to induce the collection, or (3) she can subcontract the collection activity to a third party. Based on our observations …

The Impact Of Electronic Commerce On Business-Level Strategies, Ann L. Fruhling, Lester A. Digman

Interdisciplinary Informatics Faculty Publications

This paper examines the impact of electronic commerce on business-level strategies. The paper examines electronic commerce (E.C) from the perspective of intra-business E.C., business-to-business E.C., business-to-consumer E.C., and value/supply chain management. Business-level strategies are considered to include: added-value, differentiation, cost leadership, focus, and growth source. The paper concludes that E-commerce will have significant impacts on each of the business-level strategic areas.
