摘要：Problem definition: How should retail staffing levels be set? While cost of labor is well understood, the revenue implications of having the right staffing level are hard to estimate. Moreover, these implications vary by store; hence, staffing levels should vary as well. Academic/practical relevance: We provide a novel method for setting store associate staffing at the individual store level. We discuss a field implementation that tested this methodology. Methodology: We use historical data on...

摘要：Problem definition: We conduct a controlled human-subjects experiment in a two-tier supply chain where a supplier's per-unit production cost may be private information while bargaining with a buyer. Academic/practical relevance: Academically, supply chain studies often assume full-information or highly structured bargaining. We consider private information with dynamic, unstructured bargaining. In practice, a buyer may not know its supplier's cost exactly and interact with its supplier in a ba...

摘要：Problem definition: Many healthcare providers and payers offer teletriage, a telemedicine service where concerned patients can get advice about their health condition. In theory, teletriage should help patients with an acute illness choose an appropriate provider, reducing unnecessary and duplicate provider visits, yet no study has assessed the overall costs and benefits of teletriage at a system level. Academic/practical relevance: We model the use of teletriage in managing healthcare demand ...

摘要：The (relative) cost of the customer's waiting time has long been used as a key parameter in queuing models, but it can be difficult to estimate. A recent study introduced a new queue characteristic, the value of the customer's waiting time, which measures how an increase in the total customer waiting time reduces the servers' idle time. This paper connects and contrasts these two fundamental concepts in the queuing literature. In particular, we show that the value can be equal to the cost of w...

摘要：Problem definition: Project outsourcing has been a pronounced trend in many industries but is also recognized as a major cause for project delays. We study how companies can coordinate outsourced projects with uncertain completion times through bilateral contract negotiations. Academic/practical relevance: Misaligned subcontractor incentives may result in substantial losses to both project clients and subcontractors. Coordinating subcontractors' efforts through proper contracts is imperative t...

摘要：Problem definition: In this paper, we consider a supply chain with a manufacturer and two retailers who are contracted through wholesale prices or two-part tariffs. We depart from the existing literature by assuming that contract terms between the manufacturer and a retailer are not observed by the rival retailer. Academic/practical relevance: Although the existing literature typically assumes that they are common knowledge in the market, contract terms may not be observed by rival retailers u...

摘要：Problem definition: Firms developing novel and innovative products regularly face a canonical product development and introduction problem: introduce a proven and immediately available product or delay product introduction until the successful development of an advanced version. Academic/practical relevance: Limited access to resources for the development of an advanced version adds another wrinkle to this problem, particularly for cash-constrained start-ups. For such start-ups, the introducti...

摘要：Problem definition: We examine the importance of expert services in online materials and waste exchanges (OMWEs), which are online business-to-business markets for coordinating transactions of industrial surplus, by-products, and waste. Academic/ practical relevance: OMWEs face unique challenges because of their product mix and market characteristics. Many OMWEs have traditionally relied on a combination of routine services (online aggregation, filtered search, etc.) and expert services (selec...

摘要：Problem definition: We consider dual sourcing in a distribution network for spare parts consisting of one central warehouse and multiple local warehouses. Each warehouse keeps multiple types of repairable parts to maintain several types of capital goods. The repair shop at the central warehouse has two repair options for each repairable part: a regular repair option and an expedited repair option. Irrespective of the repair option, each repairable part uses a certain resource for its repair. I...

摘要：Problem definition: Tasks sequentially arrive, and their values to the workers who are going to perform them are independent random variables. The common way to allocate tasks to workers is according to the first-in, first-out order. But this method both is inefficient and seems unfair to those who receive a low-valued task after a long wait. We are looking for a better allocation method. Academic/practical relevance: Finding a fair and efficient task allocation method is an aspiration of manp...
