摘要：Online user-generated reviews have received significant importance in the literature as they help consumers make consumption decisions. However, despite significant developments in this domain in the past decade, little attention has been paid to how narrative aspects of reviews affect consumers' consumption decisions and, consequently, influence sales. A narrative can be defined as a sequentially structured discourse that provides an understanding of the events that unfold around the narrator...

摘要：Over 60% of decedents in the United States have not given first-person consent for tissue donation; thus, receiving consent from next-of-kin (NOK) is a potentially powerful way to improve access to donor tissues. As a more informed NOK is more likely to consent to tissue donation, we introduced the delivery of two alternative videos that discuss the benefits of donation as part of the donation request. One was an animated, freely available video developed by the US Health Resources and Service...

摘要：In service systems with heterogeneous customers, prioritization with respect to the relative importance of customers is known to improve certain performance measures. However, in many applications, information necessary to determine the importance level of a customer may not be available immediately but can be revealed only through some preliminary investigation, which is sometimes called triage. This triage process is typically error-prone and may take substantial amount of time, and hence, i...

摘要：We consider a single-period manufacturing problem wherein a risk-neutral manufacturer procures product components from an upstream supplier. Component quality is uncertain. Dysfunctional components result in defective products associated with an external failure cost. There is external financing pressure related to financial stress. The manufacturer can use the internal cash-flow and a collateralized loan to manage product quality risk through incoming inspection, business insurance, and cash ...

摘要：We document the evolution of academic research through a bibliometric analysis of 123 retail analytics articles published in top operations management journals from 2000 to 2020. We isolate nine decision areas via manual coding that we verify using automated text analysis (topic modeling). We track variation across decision areas and method-usage evolution per analytics type, featuring the degree to which big data (e.g., clickstream, social media, product reviews) and analytics suited for thes...

摘要：We study the model-based undiscounted reinforcement learning for partially observable Markov decision processes (POMDPs). The oracle we consider is the optimal policy of the POMDP with a known environment in terms of the average reward over an infinite horizon. We propose a learning algorithm for this problem, building on spectral method-of-moments estimations for hidden Markov models, the belief error control in POMDPs and upper confidence bound methods for online learning. We establish a reg...

摘要：We investigate an online edge-weighted bipartite matching problem with general capacity constraints. In this problem, the resources are offline and nonreplenishable with different capacities. Demands arrive online and each requests a certain amount of resources. The goal is to maximize the reward generated by successful matches. We model the offline optimization problem as a deterministic linear program (LP) and present multiple randomized online algorithms based on the solution to the offline...

摘要：Show/webrooming refers to a consumer inspecting a product at a brick-and-mortar (BM)/online retailer before purchasing it from a competing online/BM retailer. Despite retailers adopting price-matching and free-shipping policies, show/webrooming remains prevalent. We model different product value information that consumers can learn by visiting a BM retailer and researching an online retailer, and studying consumers' show/webrooming behavior in a unified model. We confirm that consumers can eng...

摘要：We investigate how volume flexibility, defined by a sourcing cost premium beyond a base capacity, at a local responsive supplier impacts the decision to reshore supply. The buyer also has access to a remote supplier that is cheaper with no restrictions on volume flexibility. We show that with unit lead time difference between both suppliers, the optimal dual sourcing policy is a modified dual base-stock policy with three base-stock levels S-1(f), S-2(f), and S-s. The replenishment orders are g...

摘要：In distribution channels, the growing popularity of downstream retailers is a cause of both delight and despair for their upstream suppliers. While such retailers can generate more sales for the suppliers, they may also have higher leverage during any bargaining. This paper uses an analytical model to explore how a supplier's preference about the structure of her retail distribution channel is shaped by (1) the level of substitutability between the end products sold by the retailers, (2) the c...
