摘要：We investigate a server's best queue disclosure strategy in a single-server service system with an uncertain quality level (which is assumed to be binary). We consider this problem from the perspective of a Bayesian persuasion game. The server first commits to a possibly mixed strategy stating the probability that the queue length will be revealed to customers on their arrival given a realized quality level. The service quality level is then realized, and the server's corresponding queue-discl...

摘要：Consider a single-product, make-to-stock, risk-averse company that manages its finished goods inventory by a basestock policy. Item demand is modeled as a Poisson process, and unit production time is modeled as an exponential random variable. Annual cost is equal to the sum over one year of the inventory-holding and back-ordering costs. The company wants to minimize the annual cost conditional value-at-risk by an appropriate basestock selection called the optimal basestock. After offering evid...

摘要：In some stockout situations, a retailer may be better off declining to fulfill some demand even though it could have been backordered. We study the conditions under which endogenous (retailer-driven) partial backordering is the cost-minimizing strategy in an infinite horizon periodic review inventory system with dual sourcing. At the beginning of each period, the retailer can place two orders. The first order (with higher unit purchase cost) is delivered immediately from the fast supplier and ...

摘要：In this study, we develop a game-theoretic model to study the encroachment and information sharing decisions in a supply chain with a manufacturer selling through an online retail platform. In the base model, the manufacturer decides whether to encroach or not by selling through an agency channel, in addition to an existing reselling channel, at the same platform, who decides whether or not to share information with the manufacturer. We fully characterize the equilibrium decisions and show how...

摘要：The past decade has witnessed the explosive implementation of corporate social tools and technologies such as corporate internal online communities. However, there is little empirical evidence on whether and to what extent the implementation of an internal online community affects individual job performance in the geographically dispersed organization. In this study, we investigate this question with a quasi-natural experiment: A large manufacturer (i.e., the company) introduced an internal on...

摘要：Empirical research in operations management (OM) has made rapid strides in the last 30 years, and increasingly, OM researchers are leveraging methods used in the econometrics and statistics literature to assess the causal effects of interventions. We discuss the two key challenges in assessing causality with observational data (i.e., baseline bias, differential treatment effect bias) and how dominant identification approaches such as matching, instrumental variables, regression discontinuity, ...

摘要：Live-stream selling is becoming increasingly popular in e-commerce platforms, where streamers sell products through real-time interactions, while consumers make purchases during live-stream time. We identify several important factors to evaluate the live-stream selling: (1) the streamer's ability to sell, which brings an extra value to consumers through real-time illustrations and social interactions; (2) whether the extra value is positively or negatively correlated to consumers' preference v...

摘要：This paper considers a single-stage make-to-stock production-inventory system under random demand and random yield, where defective units are reworked. We examine how to set cost-minimizing production/order quantities in such imperfect systems, which is challenging because a random yield implies an uncertain arrival time of outstanding units and the possibility of them crossing each other in the pipeline. To determine the order/production quantity in each period, we extend the unit-tracking/de...

摘要：Hunger occurs in all locations around the globe, from developing to developed countries. In fact, there were over 37 million food insecure individuals (those without access to consistent nutritious food) in the United States in 2018, and this number increased in recent years due to the COVID pandemic. In many countries, food banks are used to consolidate food donations from individuals or government agencies and then provide that food to local partner agencies (such as food pantries and soup k...
