Contracting Mechanisms For Stable Sourcing Networks, Jennifer K. Ryan, Lusheng Shao, Daewon Sun

Department of Supply Chain Management and Analytics: Faculty and Staff Publications

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 …

Inventory Sharing And Demand-Side Underweighting, Hui Zhao, Liang Xu, Enno Siemsen

Department of Supply Chain Management and Analytics: Faculty and Staff Publications

Problem definition: Transshipment/inventory sharing has been used in practice because of its risk-pooling potential. However, human decision makers play a critical role in making inventory decisions in an inventory sharing system, which may affect its benefits. We investigate whether the opportunity to transship inventory influences decision makers’ inventory decisions and whether, as a result, the intended risk-pooling benefits materialize.

Academic/practical relevance: Previous research in transshipment, which is focused on finding optimal stocking and sharing decisions, assumes rational decision making without any systematic bias. As one of the first to study inventory sharing from a behavioral perspective, …

Inducing Compliance With Post-Market Studies For Drugs Under Fda’S Accelerated Approval Pathway, Liang Xu, Hui Zhao, Nicholas C. Petruzzi

Department of Supply Chain Management and Analytics: Faculty and Staff Publications

Problem definition: In 1992, FDA instituted the accelerated approval pathway (AP) to allow promising drugs to enter the market based on limited evidence of efficacy, thereby permitting manufacturers to verify true clinical benefits through post-market studies. However, most postmarket studies have not been completed as promised. We address this non-compliance problem.

Academic/Practical Relevance: The prevalence of this non-compliance problem poses considerable public health risk, thus compromising the original purpose of a well-intentioned AP initiative. We provide an internally consistent and implementable solution to the problem through a comprehensive analysis of the myriad complicating factors and tradeoffs facing FDA.

Can Contracts Replace Qualification In A Sourcing Process With Competitive Suppliers And Imperfect Information?, Yue Jin, Jennifer K. Ryan

Department of Supply Chain Management and Analytics: Faculty and Staff Publications

This paper considers a manufacturer who outsources the production of a product to multiple competing suppliers, who differ in their cost structures and in their capabilities for producing high-quality products. The manufacturer must design the sourcing process to ensure that the selected supplier has sufficient quality capability, while encouraging competition among the suppliers. We develop and analyze a mathematical model of performance-based contracting, a sourcing method that is appropriate when the manufacturer has imperfect information regarding the suppliers’ costs and capabilities. We compare the performance of performance-based contracting with that of a two-stage sourcing process, an alternative sourcing method that …

Department of Supply Chain Management and Analytics: Faculty and Staff Publications

This paper considers a sourcing problem faced by a manufacturer who outsources the manufacturing of a product to one of several competing suppliers, whose cost and quality capabilities are unknown. We consider a two-stage sourcing process in which the first stage is the qualification stage, while the second stage is the supplier selection stage. In the first stage, the manufacturer exerts effort to learn about the quality level of each of the suppliers and then must determine the set of qualified suppliers, subject to some tolerance for error. In the second stage, the manufacturer runs a price-only procurement auction, in …

Coordinating A Supply Chain With A Manufacturer-Owned Online Channel: A Dual Channel Model Under Price Competition, Jennifer K. Ryan, Daewon Sun, Xuying Zhao

Department of Supply Chain Management and Analytics: Faculty and Staff Publications

We consider a dual channel supply chain in which a manufacturer sells a single product to end-users through both a traditional retail channel and a manufacturer-owned direct online channel. We adopt a commonly used linear demand substitution model in which the mean demand in each channel is a function of the prices in each channel.We model each channel as a news vendor problem, with price and order quantity as decision variables. In addition, the manufacturer must choose the wholesale price to charge to the independent retailer. We analyze the optimal decisions for each channel and prove the existence of a …

Simulating School Closure Policies For Cost Effective Pandemic Decision Making, Ozgur M. Araz, Paul Damien, David A. Paltiel, Sean Burke, Bryce Van De Geijn, Alison Galvani, Lauren Ancel Meyers

Department of Supply Chain Management and Analytics: Faculty and Staff Publications

Background: Around the globe, school closures were used sporadically to mitigate the 2009 H1N1 influenza pandemic. However, such closures can detrimentally impact economic and social life.

Methods: Here, we couple a decision analytic approach with a mathematical model of influenza transmission to estimate the impact of school closures in terms of epidemiological and cost effectiveness. Our method assumes that the transmissibility and the severity of the disease are uncertain, and evaluates several closure and reopening strategies that cover a range of thresholds in school-aged prevalence (SAP) and closure durations.

Results: Assuming a willingness to pay per quality adjusted life-year (QALY) …
