摘要：Problem definition: We study the management of social responsibility in a three-tier supply chain with a tier 2 supplier selling to a tier 1 supplier, in turn selling to a tier 0 buyer. The tier 2 supplier may violate social and environmental standards, resulting in harm to all firms in the supply chain; we analyze the equilibrium allocation of costly effort by each firm to improve responsibility in tier 2. We also examine how pressure from external stakeholders (consumers, nongovernmental org...

摘要：Problem definition: Lack of patient adherence to treatment protocols is a main barrier to reducing the global disease burden of tuberculosis (TB). We study the operational design of a treatment adherence support (TAS) platform that requires patients to verify their treatment adherence on a daily basis. Academic/practical relevance: Experimental results on the effectiveness of TAS programs have beenmixed; and rigorous research is needed on how to structure these motivational programs, particula...

摘要：Problem definition: Faced with the challenge of serving beneficiaries with heterogeneous needs and under budget constraints, some nonprofit organizations (NPOs) have adopted an innovative solution: providing partially complete products or services to beneficiaries. We seek to understand what drives an NPO's choice of partial completion as a design strategy and how it interactswith the level of variety offered in the NPO's product or service portfolio. Academic/practical relevance: Although par...

摘要：Problem definition: This study addresses three important questions concerning the effectiveness of stay-at-home orders and sociodemographic disparities. (1) What is the average effect of the orders on the percentage of residents staying at home? (2) Is the effect heterogeneous across counties with different percentages of vulnerable populations (defined as those without health insurance or who did not attend high school)? (3) If so, why are the orders less effective for some counties than for ...

摘要：Problem definition: Achieving broad access to health services (a target within the sustainable development goals) requires reaching rural populations. Mobile healthcare units (MHUs) visit remote sites to offer health services to these populations. However, limited exposure, health literacy, and trust can lead to sigmoidal (S-shaped) adoption dynamics, presenting a difficult obstacle in allocating limited MHU resources. It is tempting to allocate resources in line with current demand, as seen i...

摘要：Problem definition: Machine learning is often employed in appointment scheduling to identify the patients with the greatest no-show risk, so as to schedule them into or right after overbooked slots. That scheduling decision maximizes the clinic performance, as measured by a weighted sum of all patients' waiting time and the provider's overtime and idle time. However, if a racial group is characterized by a higher no-show risk, then the patients belonging to that racial group will be scheduled ...

摘要：Are we contributing positively to the society at large by research that we conduct in the field of Operations Management? Currently, the answer is probably closer to no than to yes. We often do not realize it, but there is very real cost of conducting our research nonresponsibly. In this invited OM Forum contribution, which is based on my Manufacturing and Service Operations Management Distinguished Fellow lecture given at the University of Texas at Dallas in 2018, I discuss what I believe it ...

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...

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...
