  摘要：This paper studies a global sourcing problem where a buyer sources a product from a supplier to satisfy uncertain market demand. With the increasing length and complexity of today's global supply chains, the buyer may face two issues when designing the sourcing contract: adverse selection (i.e., the supplier's cost structure is private information) and noncontractible capacity (i.e., the supplier's capacity investment is not contractible). We show that noncontractible capacity does not necessa...

  摘要：We investigate when a buyer seeking to procure multiple units of an input may find it advantageous to run a test auction in which she has incumbent suppliers bid on a portion of the desired units. The test auction reveals incumbent supplier cost information that helps the buyer determine how many entrants (if any) to recruit at a cost prior to awarding the remaining units. The optimal number of entrant suppliers to recruit follows a threshold policy that is monotonic in the test auction's clea...

  摘要：We consider a practical dynamic pricing problem with two substitutable products involving a number of business rules commonly seen in practice. Demand substitution exists between the two products (interproduct substitution) and may also exist across different time periods (intertemporal substitution). However, there is limited demand information such that the underlying probability distributions of the demand cannot be characterized precisely. We use an interval to represent, respectively, the...
• Dynamic Scheduling in a Many-Server, Multiclass System: The Role of Customer Impatience in Large Systems AI翻译

  摘要：Problem definition: We study optimal scheduling of customers in service systems, such as call centers. In such systems, customers typically hang up and abandon the system if their wait for service is too long. Such abandonments are detrimental for the system, and so managers typically use scheduling as a tool to mitigate it. In this paper, we study the interplay between customer impatience and scheduling decisions when managing heterogeneous customer classes. Academic/practical relevance: Call...
• Effects of Assortment Breadth Announcements on Manufacturer Competition AI翻译

  摘要：Retailers typically use assortment planning to maximize store profits given product characteristics. We study the manufacturers' price-setting interactions and how these can be manipulated by the retailer's assortment strategy. We show that constraining the breadth of the assortment has two main effects on retailer profits: First, a larger assortment may intensify competitive pressure and decrease prices because manufacturers need to fight harder for market share. Second, a smaller assortment ...
• Dynamic Risk Management of Commodity Operations: Model and Analysis AI翻译

  摘要：Adverse commodity prices can cause significant negative cash flows and expose firms that deal in commodities to financial distress. In this paper we consider the dynamic risk management problem for a commodity processor operating in a partially complete market, facing both price uncertainty and significant financial distress costs. The firm procures an input commodity, processes it to produce an output commodity, and trades the output commodity in each period over a multiperiod horizon. The fi...
• Simple Policies for Managing Flexible Capacity AI翻译

  摘要：In many scenarios, a fixed capacity is shared flexibly between multiple products. To manage such multiproduct systems, firms need to make two sets of decisions. The first one requires setting an inventory target for each product, and the second requires dynamically allocating the scarce capacity among the products. It is not known how to make these decisions optimally. In this paper, we propose easily implementable policies that have both theoretical and practical appeal. We first suggest simp...
• Threshold-Based Allocation Policies for Inventory Management of Red Blood Cells AI翻译

  摘要：Under current regulations, red blood cell (RBC) units can be transfused to patients up to 42 days after donation. However, recent studies suggest an association between the age of transfused RBCs and adverse clinical outcomes for their recipients. Therefore, there is an interest in inventory management policies that could reduce the age of transfused RBCs without compromising their availability. In this work, we study the performance of a practical family of threshold-based allocation policies...
