  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 ...
• Ordering Behavior and the Impact of Allocation Mechanisms in an Integrated Distribution System AI翻译

  摘要：We study the impact of three well-known inventory allocation mechanisms, including proportional, linear, and uniform, on the ordering behavior of retailers serviced from a central distribution center. Based on the allocation mechanism, retailers may have an incentive to adjust (either inflate or deflate) their orders to gain a more favorable allocation, a behavior that may reduce allocation efficiency from a system perspective. We find that while all three mechanisms are centrally optimal unde...
• Permeation of the term analytics in production and operations management research AI翻译

  摘要：This is an exploratory study to analyze the permeation of the term/word analytics in the operations management domain by reviewing 2175 papers published in the Production and Operations Management journal (POMJ) since its inception in the winter 1992 until the summer of 2022. We identify the words that commonly precede the term analytics in these papers. We also identify the most common words that appear in the research papers in which the term analytics has appeared. This analysis allows us t...
• Industry 4.0 technologies: Empirical impacts and decision framework AI翻译
  作者：Bai, Chunguang; Li, H. Alice; Xiao, Yongbo

  摘要：Industry 4.0 technologies have been regarded as powerful means to enhance a firm's competitiveness in the Internet of Things environment. However, implementing Industry 4.0 technologies calls for considerable capital expenditure and might interrupt normal production in the short term. This study conducts an empirical analysis of the impact of investing in Industry 4.0 technologies based on a sample of 563 investment announcements of publicly listed firms on the Shanghai Stock Exchange and Shen...
• Let them stay or let them go? Online retailer pricing strategy for managing stockouts AI翻译
  作者：Zhang, Xingyue (Luna); Dearden, James A.; Yao, Yuliang
  作者单位：University of Washington; University of Washington Tacoma; Lehigh University; Lehigh University
  摘要：A challenge for online retail firms is managing stockouts of products when substitutes are available. We develop a game-theoretic model to analyze the competition between multiple-product online firms and characterize the scenarios when they can use prices as stockout recovery mechanisms. Depending on the consumer costs of searching for unfamiliar substitute products on their sites and the consumer mismatch costs of shopping at backup compared to favorite firms, in our primary analysis, we dem...
• The risk of algorithm transparency: How algorithm complexity drives the effects on the use of advice AI翻译
  作者：Lehmann, Cedric A.; Haubitz, Christiane B.; Fuegener, Andreas; Thonemann, Ulrich W.
  作者单位：University of Cologne
  摘要：Although algorithmic decision support is omnipresent in many managerial tasks, a lack of algorithm transparency is often stated as a barrier to successful human-machine collaboration. In this paper, we analyze the effects of algorithm transparency on the use of advice from algorithms with different degrees of complexity. We conduct a set of laboratory experiments in which participants receive identical advice from algorithms with different levels of transparency and complexity. Our results ind...
• Managing Software-as-a-Service: Pricing and operations AI翻译
  作者：Li, Bo; Kumar, Subodha
  作者单位：Pennsylvania Commonwealth System of Higher Education (PCSHE); Temple University
  摘要：Software-as-a-service (SaaS) applications have experienced a decade of explosive growth, eliminating barriers in reaching users and enabling real-time interchanges and intelligence. Using business analytics, SaaS applications are increasingly embedded in the day-to-day activities of businesses and consumers with competition and innovative pricing. Due to the evolution in cloud business models, new issues are surfacing to challenge practitioners and scholars. A number of issues encountered in t...

• Why emerging supply chain technologies initially disappoint: Blockchain, IoT, and AI AI翻译
  作者：Sodhi, ManMohan S.; Seyedghorban, Zahra; Tahernejad, Hossein; Samson, Danny
  作者单位：City St Georges, University of London; University of Melbourne; Deakin University
  摘要：In this paper, we explore why users' experiences with emerging supply chain technologies comprise inflated expectations followed by disappointment in the early stages of adoption, as per the Gartner Hype Cycle. We used affordance theory to study how managers perceive emerging technologies to explain their adoption experience. Affordance theory indicates that perceived benefits-and goals and constraints-depend on the interaction between technology and the users, not on the technology alone. Fir...
