From Trees To Treewidth: Inventory Management In Complex Supply Chain Networks, Philippe Blaettchen, Andre Calmon, Georgina Hall, Mohit Tawarmalani

Research Collection Lee Kong Chian School Of Business

We propose an exact solution approach to the Guaranteed Service Model (GSM), one of the most widely applied models for optimizing safety stock placement in supply chain networks. Based on linear programming (LP), our approach handles any directed acyclic network and any cost function that depends on a stage's incoming and outgoing service times. It scales polynomially in the number of nodes n in the network, and exponentially in its treewidth, which quantifies how "tree-like" a network is, and can be much smaller than n. This contrasts with existing approaches, which scale exponentially in n. The proof of exactness of …

R&D Consortia In Competitive Supply Chains, Pascale Crama, Gaoyan Lu, Yi Xu

Research Collection Lee Kong Chian School Of Business

R&D consortia, which coordinate R&D activities of their member firms, have been successful in many industries. We study a model with two competing supply chains each consisting of a manufacturer and a supplier. The manufacturers compete in the final product market, and can conduct R&D to reduce unit product costs of their final products. The R&D can be done in three different ways: by the two manufacturers independently, by them jointly in a horizontal R&D consortium, or by the supplier and the manufacturer jointly in each supply chain in two vertical R&D consortia. We find that as compared to independent …

Optimal Channel Strategy Of Luxury Brands In The Presence Of Online Marketplace And Copycats, Sarah Yini Gao, Wei Shi Lim, Ziqiu Ye

Research Collection Lee Kong Chian School Of Business

The strategic interaction between authentic luxury brands and their copycats has evolved since the proliferation of online marketplaces. Using a game-theoretic framework, we examine how an authentic luxury brand, observing the strategic behavior of its competing copycats, should make its optimal entry decision to a third-party online marketplace. Our findings reveal that the authentic luxury brand does not sell on the online marketplace when either the quality or the physical resemblance of the copycat to the authentic luxury brand is high. This contributes to the related literature by offering an explanation for the increasing quality of copycats amid the e-commerce …

Problem definition: We study profit allocation for a sourcing network, in which a buyer sources froma set of differentiated suppliers with limited capacity under uncertain demand for the final product. Whereas the buyer takes the lead in forming the sourcing network and designing the contract mechanism, due to their substantial bargaining power, the suppliers take the lead in determining the terms of the contract. Academic/practical relevance: We identify contracting mechanisms that will ensure the stability of the sourcing network in the long term, where a stable sourcing network requires an effective profitallocation scheme that motivates all members to …

Customer’S Operational Efficiency And Trade Credit Provision, Wai Ho Chan

Lingnan Theses (MPhil & PhD)

This study examines whether the trade credit provision is affected by customers’ operational efficiency. We link the supplier firms with their major customers using the Customer Segment database in order to identify the trade credit provision for each pair of supplier-customer relationships. While suppliers have the incentive to provide trade credit to high-quality customers in order to increase market share, excess trade credit would also harm the suppliers once the customers default. Our empirical results indicate that operational efficiency and trade credit are positively associated. This finding supports the view that suppliers tend to select and provide trade credit to …

The Dynamics And Effects Of Supply Network Structure, Marat Davletshin

Graduate Theses and Dissertations

The rising interest in network theory among supply chain scholars reflects an emerging shift in perspective. To deliver global speed, efficiency, and responsiveness, modern firms’ supply chains are becoming increasingly complex. The patterns of interactions and interdependencies among hundreds of firms interconnected by these complex supply chains cannot be adequately explored from the dyadic perspective, which has dominated supply chain research for decades. Many supply chain scholars agree that the language of networks can provide a syntax and structure to describe and explore this complex reality. The actual application of network theory in supply chain research, however, has been limited. …
