摘要：Problem definition: A major task in retail operations is to optimize the assortments exhibited to consumers. To this end, retailers need to understand customers' preferences for different products. Academic/practical relevance: This is particularly challenging when only sales and product-availability data are recorded, and not all products are displayed in all periods. Similarly, in revenue management contexts, firms (airlines, hotels, etc.) need to understand customers' preferences for differ...

摘要：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 t...

摘要：Problem definition: We analyze a contract in which a supplier who is exposed to disruption risk offers a supply-flexibility contract comprising of a wholesale price and a minimum-delivery fraction (flexibility fraction) to a buyer facing random demand. The supplier is allowed to deviate below the order quantity by at most the flexibility fraction. The supplier's regular production is subject to random disruption, but she has access to a reliable expedited supply source at a higher marginal cos...

摘要：Problem definition: When sourcing through a procurement service provider (PSP), the PSP often collects rebates from unethical manufacturers in developing countries (as referral fees) that are hidden from the retailers. Recognizing that a PSP has a strong incentive to solicit quotes from unethical manufacturers, we examine a situation in which the retailer insists on soliciting a quote from a manufacturer designated by the retailer and a separate quote from an unethical manufacturer selected by...

摘要：We provide a set of data on cross-border e-commerce sales from a fast-fashion e-retailer, Babyonlinedress, which stocks wedding gowns and full dresses from China but sells to markets overseas through multiple cross-border platforms, including Amazon, AliExpress, DHgate, etc. The data set contains normalized weekly orders on Amazon Marketplace over a three-year period, from January 1, 2015 to December 31, 2017. In total, we have collected M = 13,719 weekly orders for N = 1,166 different stock k...

摘要：Problem definition: We examine a dynamic assignment problem faced by a large wireless service provider (WSP) that is a Fortune 100 company. This company manages two warranties: (i) a customer warranty that the WSP offers its customers and (ii) an original equipment manufacturer (OEM) warranty that OEMs offer the WSP. The WSP uses devices refurbished by the OEM as replacement devices, and hence their warranty operation is a closed-loop supply chain. Depending on the assignment the WSP uses, the...

摘要：Problem definition: Recently, there has been a rapid rise of on-demand ridehailing platforms, such as Uber and Didi, which allow passengers with smartphones to submit trip requests and match them to drivers based on their locations and drivers' availability. This increased demand has raised questions about how such a new matching mechanism will affect the efficiency of the transportation system-in particular, whether it will help reduce passengers' average waiting time compared with traditiona...

摘要：Problem definition: We study sourcing behavior in severe conditions where supply disruptions are rare but carry the potential of wiping out several rounds worth of a firm's profit. Academic/practical relevance: The tradeoff between scale economies from supplier consolidation and risk mitigation from supplier diversification is at the core of firms' sourcing strategy and one that is empirically understudied. Methodology: We study supplier diversification through a behavioral lens and test theor...

摘要：As the nature of work has become more service oriented, knowledge intensive, and rapidly changing, people-be they workers or customers-have become more central to operational processes and have impacted operational outcomes in novel and perhaps more fundamental ways. Research in people-centric operations (PCO) studies how people affect the performance of operational processes. In this OM Forum, we define PCO as an area of study, offer a categorization scheme to take stock of where the field ha...
