  摘要：Limited guidance is available for providing patient-specific care to hypertensive patients, although this chronic condition is the leading risk factor for cardiovascular diseases. To address this issue, we develop an analytical model that takes into account the most relevant risk factors including age, sex, blood pressure, diabetes status, smoking habits, and blood cholesterol. Using the Markov Decision Process framework, we develop a model to maximize expected quality-adjusted life years, as ...

  摘要：Hospitals in the United States (U.S.), and the healthcare industry as a whole, are experiencing major transformations that will likely affect every facet of our society. One such example is a federal regulation known as the Value-based Purchasing (VBP) program, which shifts hospital reimbursements for services rendered away from a fee-for-service model to a value-based model. This change requires hospitals to more accurately track and document resources/assets utilized in the delivery of care,...

  摘要：Adequate length of stay (LOS) during hospitalization is not only a critical determinant of quality of care, but can be a useful predictor of the risk of future readmissions. Recent studies have shown alarming evidence that the United States leads developed nations in terms of shorter hospital stays, rendering patients with greater risk of future readmissions. We focus on deviation between hospital LOS and the geometric mean LOS (GMLOS), a guideline for care delivery stipulated by the Centers f...

• How Do Consumers Choose between Multiple Product Generations and Conditions? An Empirical Study of iPad Sales on eBay AI翻译

  摘要：Many companies are reluctant to enter the remanufacturing market because of concern with cannibalization of new sales, competition from current remanufacturers, and the willingness of consumers to purchase remanufactured products. What is often missing, however, is an in-depth understanding of how consumers make complex purchase decisions involving remanufactured items among numerous other options. This study examines how consumers evaluate remanufactured products when there are multiple condi...
• Running Behavioral Operations Experiments Using Amazon's Mechanical Turk AI翻译

  摘要：Mechanical Turk (MTurk), an online labor market run by Amazon, provides a web platform for conducting behavioral experiments; the site offers immediate and inexpensive access to a large subject pool. In this study, we review recent research about using MTurk for behavioral experiments and test the validity of using MTurk for experiments in behavioral operations management. We recruited subjects from MTurk to replicate the inventory management experiment from Bolton and Katok (), as well as the...
• Big Data in Supply Chain Management AI翻译

  作者单位：Northeastern University; William & Mary
  摘要：Big data has become ubiquitous. It is impacting every aspect of how companies organize and manage their supply chains. Supply chains are evolving into digital networks connected via devices and sensors revolutionizing how data is generated, shared, and communicated. It is also unlocking new research streams. In this study, we introduce papers in this issue and showcase Big Data research trends across supply chain management.
• Using Data and Big Data in Retailing AI翻译
  作者：Fisher, Marshall; Raman, Ananth
  作者单位：University of Pennsylvania; Harvard University
  摘要：In this essay, we examine how retailers can use data to make better decisions and hence, improve their performance. We have been studying retail operations for over two decades and have witnessed many, and been personally involved in a few, projects that delivered considerable value to retailers by better exploiting data. We highlight a few of these examples and also identify some other potential applications.
• Incentive Programs for Reducing Readmissions when Patient Care is Co-Produced AI翻译

  作者单位：Hautes Etudes Commerciales (HEC) Paris; University of California System; University of California Los Angeles
  摘要：To reduce preventable readmissions, many healthcare systems are transitioning from fee-for-service (FFS) to other reimbursement schemes such as pay-for-performance (P4P) or bundled payment (BP) so that the funder of a healthcare system can transfer to the hospital some of the financial risks associated with patient rehospitalizations. To examine the effectiveness of different schemes (FFS, P4P, and BP), we develop a health co-production model in which the patient's readmissions can be jointly ...
• The Forest or the Trees? Tackling Simpson's Paradox with Classification Trees AI翻译
  作者：Shmueli, Galit; Yahav, Inbal
  作者单位：National Tsing Hua University; Bar Ilan University
  摘要：Studying causal effects is central to research in operations management in manufacturing and services, from evaluating prevention procedures, to effects of policies and new operational technologies and practices. The growing availability of micro-level data creates challenges for researchers and decision makers in terms of choosing the right level of data aggregation for inference and decisions. Simpson's paradox describes the case where the direction of a causal effect is reversed in the aggr...
