  摘要：Problem definition: Among the most vexing issues in the U.S. healthcare ecosystem is inappropriate use of percutaneous coronary intervention (PCI) procedures, also known as overstenting. A key driver of overstenting is physician subjectivity in eyeballing a coronary angiogram. Advanced tests such as fractional flow reserve (FFR) provide more precise and objective measures of PCI appropriateness, yet the decision to perform these tests is endogenous and not immune to clinical ambiguity associat...

  摘要：We reviewed research papers related to pandemics/epidemics (disease outbreaks of a global/regional scope) published in major operations management, operations research, and management science journals through the end of 2019. We evaluate and categorize these papers. We study research trends, explore research gaps, and provide directions for more efficient and effective research in the future. In addition, our recommendations include the lessons learned from the ongoing pandemic, COVID-19. We d...
• Forecasting Airport Transfer Passenger Flow Using Real-Time Data and Machine Learning AI翻译

  摘要：Problem definition: Airports and airlines have been challenged to improve decision making by producing accurate forecasts in real time. We develop a two-phased predictive system that produces forecasts of transfer passenger flows at an airport. In the first phase, the system predicts the distribution of individual transfer passengers' connection times. In the second phase, the system samples from the distribution of individual connection times and produces distributional forecasts for the numb...
• Understanding Customer Retrials in Call Centers: Preferences for Service Quality and Service Speed AI翻译
  作者：Hu, Kejia; Allon, Gad; Bassamboo, Achal

  摘要：Problem definition: Customers are likely to initiate retrial calls when their previous contact with a call center fails to deliver a satisfactory resolution. According to industry reports, retrials are listed as a top annoying issue for customers and hurt call centers' profits. Though recognizing this problem, call centers find it challenging to reduce retrials without overshooting their operating expenses. Our research aims to empirically understand the mechanism of customer retrials and then...
• A Model for Prepositioning Emergency Relief Items Before a Typhoon with an Uncertain Trajectory AI翻译
  作者：Uichanco, Joline
  作者单位：University of Michigan System; University of Michigan
  摘要：Problem definition: We study the problem faced by the Philippine Department of Social Welfare (DSWD) in prepositioning relief items before landfall of an oncoming typhoon whose future outcome (trajectory and wind speed) is uncertain. Academic/practical relevance: The importance of prepositioning was a hard lesson learned from Super Typhoon Haiyan that devastated the Philippines in 2013, when many affected by the typhoon did not have immediate access to food and water. In a typhoon-prone countr...
• On Co-opetitive Supply Partnerships with End-Product Rivals: Information Asymmetry, Dual Sourcing and Supply Market Efficiency AI翻译
  作者：Jung, Seung Hwan; Kouvelis, Panos
  作者单位：Yonsei University; Washington University (WUSTL)
  摘要：Problem definition:We consider opportunities for cooperation at the supply levelbetween twofirms that are rivals in the end-product market. One of ourfirms is vertically inte-grated (VI), has in-house production capabilities, and may also supply its rival. The other is adownstream outsourcing (DO)firm that has better market information. The DO is willing toconsider a supply partnership with the VI, but it also has the option to use the outside supplymarket.Academic/practical relevance:Such co-...
• Sourcing Innovation: Integrated System or Individual Components? AI翻译
  作者：Chen, Zhi; Mihm, Jurgen; Schlapp, Jochen
  作者单位：National University of Singapore; National University of Singapore; INSEAD Business School; Frankfurt School Finance & Management
  摘要：Problem definition: Most industrial innovations consist of multiple interacting components that must be combined into a final product to form an integrated system. When procuring such complex innovations from their suppliers, buyers face a substantial challenge: Should they tender the integrated system as a whole or, instead, procure the system's components individually from (possibly) different suppliers? Academic/practical relevance: Suppliers have become a major source of innovation for man...
• Gender Inequality in Research Productivity During the COVID-19 Pandemic AI翻译
  作者：Cui, Ruomeng; Ding, Hao; Zhu, Feng
  作者单位：Emory University; Harvard University
  摘要：Problem definition: We study the disproportionate impact of the lockdown as a result of the COVID-19 outbreak on female and male academic research productivity in social science. Academic/practical relevance: The lockdown has caused substantial disruptions to academic activities, requiring people to work from home. How this disruption affects productivity and the related gender equity is an important operations and societal question. Methodology: We collect data from the largest open-access pr...
• Divide and Conquer: A Hygienic, Efficient , and Reliable Assembly Line for Housekeeping AI翻译
  作者：Chen, Xiao Alison; Wang, Rowan; Zhang, Jianghua
  作者单位：University System Of New Hampshire; University of New Hampshire; Southern University of Science & Technology; Shandong University
  摘要：Problem definition: This work focuses on the hotel housekeeping process. In a field study, a possible channel of disease transmission between consecutive guests in hotel rooms is revealed. In order to prevent the transmission, an innovative assembly-line housekeeping method is developed. Academic/practical relevance: The transmission of infectious diseases during hotel stays (e.g., by touching unclean towels or bed linens) has been reported globally. Under the current COVID-19 pandemic, having...

  摘要：Problem definition: Translate data from electronic health records (EHR) into accurate predictions on patient flows and inform daily decision making at a major hospital. Academic/practical relevance: In a constrained hospital environment, forecasts on patient demand patterns could helpmatch capacity and demand and improve hospital operations. Methodology: We use data from 63,432 admissions at a large academic hospital (50% female, median age 64 years old, median length of stay 3.12 days). We co...
