  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...
• Innovations in retail operations: Thirty years of lessons from Production and Operations Management AI翻译

  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...
• A model for wind farm management with option interactions AI翻译

  摘要：A renewable energy site can expand its power generation capacity by an endogenous amount but may also want to shut down to save on fixed operating costs and interest payments if the market prospects deteriorate. We model such circumstances and derive managerial implications that help us explain real-world conundrums, illustrating the intricate interactions between the operational decision to build up capacity and the financial decision to exit an industry. Shutting down may be delayed in the h...
• Empirical newsvendor biases: Are target service levels achieved effectively and efficiently? AI翻译

  摘要：Human decision making in the newsvendor context has been analyzed intensively in laboratory experiments, where various decision biases have been identified. However, it is unclear whether the biases also exist in practice. We analyze the ordering decisions of a manufacturer who faces a multiproduct newsvendor problem with an aggregate service-level constraint. We find that the manufacturer broadly exhibits the same biases as subjects in the laboratory and is prone to another bias that has not ...
• Scheduling of Physicians with Time-Varying Productivity Levels in Emergency Departments AI翻译

  摘要：Emergency department (ED) overcrowding and long patient wait times have become a worldwide problem. We propose a novel approach to assigning physicians to shifts such that ED wait times are reduced without adding new physicians. In particular, we extend the physician rostering problem (PRP) by including heterogeneity among emergency physicians in terms of their productivity (measured by the number of new patients seen in 1 hour) and by considering the stochastic nature of patient arrivals and ...
• The Signaling Effect of Sampling Size in Physical Goods Sampling Via Online Channels AI翻译

  摘要：Prior literature has focused primarily on offline sampling of physical goods and online sampling of information goods, whereas a new form of sampling campaign-physical goods sampling via online channels-receives little attention. Leveraging a rich data set from Taobao, a large e-commerce platform in China, this study strives to understand the mechanisms of physical goods sampling via online channels. Specifically, we investigate (1) how the sampling size (number of free samples provided) acts ...
