  摘要：We study outpatient appointment block scheduling policies for single providers under conditions of patient heterogeneity in service times and patient no-shows. The objective is to find daily appointment schedules that minimize a weighted sum of patients' waiting time, the physician's idle time, and the physician's overtime. We contribute by suggesting new effective sequential block scheduling procedures motivated by actual outpatient clinic practices across the globe and grounded in the succes...

  摘要：Having accurate, unbiased prognosis information can help patients and providers make better decisions about what course of treatment to take. Using a comprehensive dataset of all colorectal cancer patients in California, we generate predictive models that estimate short-term and medium-term survival probabilities for patients based on their clinical and demographic information. Our study addresses some of the contradictions in the literature about survival rates and significantly improves pred...

  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...

  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...
• Demand and Revenue Impacts of an Opaque Channel: Evidence from the Airline Industry AI翻译

  摘要：Over time, opaque intermediaries, such as Hotwire and Priceline.com, have become an established distribution channel for the travel industry. We use a market response model and a dataset of economy class reservations from a major international airline to empirically examine the demand and cannibalization effects of the opaque channel. We find that: (1) the impact of the opaque channel on total demand is positive and significant in markets with high levels of competition; and (2) overall, the o...
