摘要:Problem definition: Internal theft poses a significant challenge in retail firms' operations. Owing to a lack of effective monitoring tools, a firm cannot observe every action in daily operations of its employees, providing opportunity for wrongdoing, such as capacity and cash stealing. As a result, a common practice is to increase the price of goods to offset the loss in revenue due to the increasing threat of theft. However, we show that such practices are not optimal. Methodology/results: W...

摘要:Problem definition: The reliability of controlled experiments, commonly referred to as A/B tests, is often compromised by network interference, where the outcomes of individual units are influenced by interactions with others. Significant challenges in this domain include the lack of accounting for complex social network structures and the difficulty in suitably characterizing network interference. Methodology/results: To address these challenges, we propose a machine learning-based method. We...

摘要:Problem definition: Care units are the facilities where admitted hospital patients receive treatment and monitoring services. This paper studies the problem of deciding which patients to place into the various available care units at any time. To determine placements in practice, hospitals rely on clinicians to discern a patient's care needs and appropriately trade-off between future demand and limited bed availability. Making the right decisions remains challenging because patients are hetero...

摘要:Problem definition: Cloud computing is a multibillion-dollar business that draws substantial capital investments from large companies such as Amazon, Microsoft, and Google. Large cloud providers need to accommodate the growing demand for computing resources while avoiding unnecessary overprovisioning of hardware and operational costs. The underlying decision processes are challenging, as they involve long-term hardware and infrastructure investments under future demand uncertainty. In this pap...

摘要:Problem definition: Given an observed procurement network, we characterize when the network structure is rationalizable as pairwise stable-that there exist preferences such that no pairs of buyers and suppliers would deviate from the existing network structure. Methodology/results: We show that the Weak Axiom of Revealed Pairwise Stability (WARPS) is a necessary and sufficient testable condition for pairwise stability. WARPS is an algorithm that checks whether a link can be added to the networ...

摘要:Problem definition: Many services rely on the prosocial behavior of consumers that benefits the wider community for effective delivery, such as bike-sharing schemes, self-service checkouts in grocery stores, and pathology screening services, yet there are frequent challenges in motivating honest, cooperative user behavior in these services. We build on existing research to argue that the degree of anonymity of users toward the service provider can be used to facilitate their prosocial behavior...

摘要:Problem definition: Improving the surplus of low-income consumers during economic distress is of primary concern for many governments. This paper uses an economic model to investigate consumers' brand switching during economic distress and highlights its disparate impact on low-income consumers. Our modeling framework also captures how retailers and national-brand manufacturers strategically adjust the market prices in response to brand switching and shelf space constraints. To generate prescr...

摘要:Problem definition: Online allocation problems with resource constraints have a rich history in operations management. In this paper, we introduce the regularized online allocation problem, a variant that includes a nonlinear regularizer acting on the total resource consumption. In this problem, requests repeatedly arrive over time, and for each request, a decision-maker needs to take an action that generates a reward and consumes resources. The objective is to simultaneously maximize additive...

摘要:Problem definition: Family engagement (FE) is an ongoing partnership between health professionals and patients' families to enhance healthcare quality, safety, and delivery. Although FE is increasingly considered an essential component of patient-centered care, its importance in influencing healthcare delivery outcomes is unclear. This study examines the impact of FE on patient care outcomes (PCOs)-specifically, patient satisfaction (PS) and readmission (Readm)-in the context of varying severi...

摘要:Problem definition: Women have been shown to prefer jobs with a better work-life balance across many fields. Given that serving as a state political representative requires a significant amount of travel between one's home district and the state capitol, this suggests that long commute distances may reduce the number of women seeking political office in the United States. At the same time, state political positions vary in their degree of flexibility (e.g., full-time versus part-time) and comm...
