摘要：Problem definition: Probabilistic selling (PS) is a business model whereby, in addition to selling transparent products, a firm sells an opaque good, which is unknown to buyers until after purchase. We examine how PS affects retailer-manufacturer interactions in markets for physical goods and how upstream competition impacts channel members' incentives to facilitate PS. Methodology/results: Using a Hotelling-based model of a multiproduct retailer, we find that a retailer maximizes its profit b...

摘要：Problem definition: Kidney paired donation programs allow patients registered with an incompatible donor to receive a suitable kidney from another donor, as long as the latter's co-registered patient, if any, also receives a kidney from a different donor. The kidney exchange problem (KEP) aims to find an optimal collection of kidney exchanges taking the form of cycles and chains. Methodology/results: We develop the first decomposition method that is able to consider long cycles and long chains...

摘要：Problem definition: We examine the environmental implications of shifting from in-person to virtual conference formats and identify the effects of such a shift on the value conferences provide to our societies. We extend work from other fields to present a more comprehensive comparison of the environmental impact and perceived value of different conference formats for the operations management/research communities. Methodology/results: We leverage a series of COVID-19-induced natural experimen...

摘要：Problem definition: In this paper, we study a predisaster relief network design problem with uncertain demands. The aim is to determine the prepositioning and reallocation of relief supplies. Motivated by the call of the International Federation of Red Cross and Red Crescent Societies (IFRC) to leave no one behind, we consider three important practical aspects of humanitarian operations: shortages, equity, and uncertainty. Methodology/results: We first employ a form of robust satisficing measu...

摘要：Problem definition: In a multistage model of a bilateral supply chain, we study two postponement strategies that the downstream retailer may adopt to mitigate the supply yield risk originating from the upstream production process. The retailer could either postpone the procurement payment until after the yield is realized and pay only for the delivered amount; postpone the pricing decision to better utilize the available supply; or do both. Although both strategies have been separately studied...

摘要：Problem definition: Generating recommendations of compatible dating partners is a challenging task for online dating platforms because uncovering users' idiosyncratic preferences is difficult. Thus, platforms tend to recommend popular users to others more frequently than unpopular users. This paper studies such popularity bias in an online dating platform's recommendations and its consequences for users' likelihood of finding dating partners. Methodology/results: Motivated by the empirical evi...

摘要：Problem definition: Quick response is a classic operations strategy that allows a retailer to place a rapid replenishment order during the selling season using information learned from early sales. The benefits of quick response are widely studied in the literature under the condition that the manufacturer's wholesale prices are exogenously given. Motivated by the practice of emerging small and medium-sized enterprise (SME) fashion brands, this paper revisits the value of quick response for a ...

摘要：Problem definition: A canonical model in service management assumes that consumers base the purchase of a service on its full price, that is, a linear combination of the monetary price and the expected time commitment. Although analytically convenient, when this assumption holds is an unexplored question. Methodology/results: We present a model of consumers allocating their time and money between working, overhead activities that do not provide utility, one continuous leisure activity, and one...

摘要：Problem definition: We consider pricing of services with strategic customers who have heterogeneous delay costs motivated by transportation systems. Customers are strategic decision makers who weigh the reward from the transport service against the waiting cost for the vehicle at a transportation station. Customers arrive at the station according to a Poisson process, and the vehicle visits the station according to a renewal process. We analyze the optimal price and the equilibrium for differe...

摘要：Problem definition: Intraproject learning in project scheduling involves the use of learning among the similar tasks in a project to improve the overall performance of the project schedule. Under intraproject learning, knowledge gained from completing some tasks in a project is used to execute similar later tasks in the same project more efficiently. We provide the first model and solution algorithms to address this intraproject learning problem. Academic/practical relevance: Intraproject lear...
