  摘要：We show simple yet optimal results to update the inventory/capacity levels, expected profit, fill rates, and service levels of substitutable resources in response to an updating of the mean demand forecasts for the resources. We find that a change in the mean demand of one resource does not affect the optimal inventory level of any other resource. The results are obtained for demands with location-scale distribution, and for a revenue structure satisfying a triangle property such that the mana...
• Clinic Capacity Management: Planning Treatment Programs that Incorporate Adherence AI翻译

  摘要：For infectious diseases like tuberculosis and HIV, treatment adherence plays an important role in treatment effectiveness and epidemic control. Studies of some infectious diseases indicate that patients who live closer to their health facilities maintain higher adherence; however, most models ignore the heterogeneity of patients' adherence. Clinics must balance knowledge about adherence with epidemic growth when creating successful treatment programs. We develop an optimization model that inte...
• Power Structure and Profitability in Assembly Supply Chains AI翻译

  摘要：This paper studies the impact of supply chain power structure on firms' profitability in an assembly system with one assembler and two suppliers. Two power regimes are investigated-in a Single Power Regime, a more powerful firm acts as the Stackelberg leader to decide the wholesale price but not the quantity whereas in a Dual Power Regime, both the price and quantity decisions are granted to the more powerful firm. Tallying the power positions of the three firms, for each power regime we study...
• The Roles of Bank and Trade Credits: Theoretical Analysis and Empirical Evidence AI翻译

  摘要：This study investigates the roles of bank and trade credits in a supply chain with a capital-constrained retailer facing demand uncertainty. We evaluate the retailer's optimal order quantity and the creditors' optimal credit limits and interest rates in two scenarios. In the single-credit scenario, we find the retailer prefers trade credit, if the trade credit market is more competitive than the bank credit market; otherwise, the retailer's preference of a specific credit type depends on the r...

  摘要：Rapid advances of information technology in recent years have enabled both the manufacturers and the retailers to operate their own Internet channels. In this study, we investigate the interaction between the capabilities of introducing the Internet channels, the pricing strategies, and the channel structure. We classify consumers into two segments: grocery shoppers attach a higher utility from purchasing through the physical channel, whereas a priori Internet shoppers prefer purchasing online...
• Balancing Revenues and Repair Costs under Partial Information about Product Reliability AI翻译

  作者单位：Cornell University
  摘要：We consider the problem faced by a company selling a product with warranty and under partial information about the product reliability. The product can fail from multiple failure types, each of which is associated with an inherently different repair cost. If the product fails within the warranty duration, then the company is required to pay the repair cost. The company does not know the probabilities associated with different failure types, but it learns the failure probabilities as sales occu...
• Bounds of Relative Regret Limit in p-Robust Supply Chain Network Design AI翻译

  摘要：This research studies the p-robust supply chain network design with uncertain demand and cost scenarios. The optimal design integrates the supplier selection together with the facility location and capacity problem. We provide a new framework to obtain the relative regret limit, which is critical in the robust supply chain design but is assumed to be a known value in the existing literature. We obtain lower and upper bounds for relative regret limit and obtain a sequence of optimal solutions f...
• Getting What You Pay For-Strategic Process Improvement Compensation and Profitability Impact AI翻译

  摘要：Profit-maximizing firm owners who incentivize their managers with a bonus for process improvement create an intentional misalignment of their own objective and management attention. From the viewpoint of a single firm, such a local misalignment can never be profitable, but in this study we take a wider strategic perspective by investigating cost-reducing process improvements of two firms competing in a Cournot market. We find that the use of a process improvement bonus (by firm A) can be profi...
