摘要：Cross-training is an important tool to improve the performance of manufacturing and service systems through dynamic worker allocation. This study investigates how cross-training can be leveraged when worker collaboration is not possible and frequent worker reassignment is undesirable. We consider a tandem queueing system with finite buffers between tasks. We show that if each worker is the fastest at a different task, then the optimal policy is always dedicated, regardless of the magnitude of ...

摘要：Real social information is believed to cause a trust-privacy paradox in e-commerce platforms, with the degree of information disclosure affecting platform performance. In this study, we split the mixed influence into the direct trust mechanism and the indirect privacy mechanism, studying each in the context of partial and full social information disclosure, respectively. Using unique data from an 80-day large-scale online experiment conducted in an e-commerce platform in China, we show that a ...

摘要：Many decisions must be made before relevant uncertainties are revealed; hence robustness approaches to decision making are often considered. There are two major approaches to robustness in the literature: (i) maximizing the value of the worst outcome and (ii) minimizing the maximum ex post regret of the decision. While the first approach seeks the best worst-case outcome, it may result in substantial opportunity losses relative to the ex post optimal decision; this is particularly critical in ...

摘要：In this article, we describe representative contributions in several major application areas of data analytics in operations management to summarize the recent development, discuss the common themes, identify the current trends, and speculate the future directions. Certainly, many important contributions have been made in various application areas that are either directly or indirectly related to data analytics, and there are important theoretical developments made by scholars in our field. It...

摘要：We review papers published in POM during its thirty-year history that deal with retail operations issues with an empirical approach. The papers span a range of issues, from traditional ones like forecasting and inventory planning, to new technologies, like radio frequency identification (RFID) and e-commerce, and strategic, like links between retailing and stock market performance.

摘要：Prostate cancer (PCa) is common in American men with long latent periods, during which the disease is asymptomatic. Active surveillance is a monitoring strategy commonly used for patients diagnosed with low-risk PCa who may harbor latent high-risk PCa. The optimal monitoring strategy attempts to minimize the disutility of testing while ensuring that the patient is detected at the earliest time when the disease progresses. Unfortunately, guidelines for the active surveillance of PCa are often o...

摘要：We study the risk management strategies of two manufacturers that procure a commodity from a supplier to produce a final product and compete in a downstream market. The manufacturers can adopt financial hedging to reduce profit variability or spot trading to mitigate the demand-supply mismatch risk, and they can also combine these two strategies or adopt neither of them. We characterize the equilibria of several representative games where two different risk management strategies are available,...

摘要：Customers are increasingly utilizing location-based services via mobile devices to engage with retail establishments. The focus of this paper is to identify factors that help to drive venue popularity revealed by location-based services, which then better facilitate companies' operational decisions, such as procurement and staff scheduling. Using data collected from Foursquare and Yelp, we build, evaluate, and compare a wide variety of machine learning methods including deep learning models wi...
