Proactive management of SARS-CoV-2 requires timely and complete population data to track the evolution of the virus and identify at risk populations. However, many cases are asymptomatic and are not easily discovered through traditional testing efforts. Sentinel surveillance can be used to estimate the prevalence of infections for geographical areas but requires identification of sentinels who are representative of the larger population. Our goal is to evaluate applicability of a population of labor and delivery patients for sentinel surveillance system for monitoring the prevalence of SARS-CoV-2 infection. We tested 5307 labor and delivery patients from two hospitals in Phoenix, Arizona, …

Contracting Mechanisms For Stable Sourcing Networks, Jennifer K. Ryan, Lusheng Shao, Daewon Sun Oct 2020

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 Jan 2020

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 Jan 2020

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.

Methodology: We …

Dynamic Pricing Of Wireless Internet Based On Usage And Stochastically Changing Capacity, Demet Batur, Jennifer K. Ryan, Zhongyuan Zhao, Mehmet C. Vuran

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

(1) Problem Definition: Inspired by new developments in dynamic spectrum access, we study the dynamic pricing of wireless Internet access when demand and capacity (bandwidth) are stochastic. (2) Academic / Practical Relevance: The demand for wireless Internet access has increased enormously. However, the spectrum available to wireless service providers is limited. The industry has thus altered conventional license- based spectrum access policies through unlicensed spectrum operations. The additional spectrum obtained through these operations has stochastic capacity. Thus, the pricing of this service by the service provider has novel challenges. The problem considered in this paper is therefore of high practical …

Can Contracts Replace Qualification In A Sourcing Process With Competitive Suppliers And Imperfect Information?, Yue Jin, Jennifer K. Ryan Jan 2016

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 …


Resource Planning In Engineering Services Firms, Vincent Hargaden, Jennifer K. Ryan Jan 2015

Resource Planning In Engineering Services Firms, Vincent Hargaden, Jennifer K. Ryan

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

We develop a model to enable engineering professional services firms to improve the management of their competitive resources, i.e., skilled engineers, to be better able to respond to customer demand. The model was informed by semistructured interviews with senior executives from engineering, information technology (IT) services and technical consulting firms. As a result, we capture many of the complexities associated with the resource planning process in the professional engineering services sector. In the resulting model, the key attributes of supply, demand, and operations constraints are identified. Based on information obtained from the interviews, a number of test firms are created.We …


Two Stage Procurement Processes With Competitive Suppliers And Uncertain Supplier Quality, Yue Jin, Jennifer K. Ryan, Walter Yund Jan 2014

Two Stage Procurement Processes With Competitive Suppliers And Uncertain Supplier Quality, Yue Jin, Jennifer K. Ryan, Walter Yund

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 Jan 2013

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) …


Grain Transportation Problems In Nebraska -- Causes And Cures. Proceedings Of The Nebraska Grain Transportation Seminar, Dale G. Anderson, Dean Linsenmeyer, Michael S. Turner Dec 1979

Grain Transportation Problems In Nebraska -- Causes And Cures. Proceedings Of The Nebraska Grain Transportation Seminar, Dale G. Anderson, Dean Linsenmeyer, Michael S. Turner

Department of Agricultural Economics: Faculty Publications

The Nebraska feed grain and soybean harvest of 1979 was one which will not soon be forgotten by those who participated in its production and marketing. Yields and production broke all previous records. Record export demands for the crop placed record service requirements on transportation and handling systems. Record movements of grain from farms to elevators and to inland and export terminals were reported. At the same time, complaints of inadequate capacity to store and transport the grain were perhaps also of all-time record proportions. Corn and milo accumulated in open piles on farms and at country collection points. Problems …
