摘要：Problem Definition: Proficiency in many sophisticated tasks is attained through experience-based learning, in other words, learning by doing. For example, transplant centers' surgical teams need to practice difficult surgeries to master the skills required. Meanwhile, this experience-based learning may affect other stakeholders, such as patients eligible for transplant surgeries, and require resources, including scarce organs and continual efforts. To ensure that patients have excellent outcom...

摘要：Problem definition: This paper examines frictions in the shopping funnel using empirical clickstream data from an online travel platform. We analyze (a) customers' heterogeneous search and purchase behaviors and (b) their reactions to changes in assortment size. We then develop a consider-then-choose model to generalize our findings. Methodology/results: We characterize the online customer journey as a two-stage consider-thenchoose framework. In the consider stage, we analyze the consideration...

摘要：Problem definition: We study advance selling and upgrading in a priority queue setting that emerges in the amusement park industry. Customers choose to buy fast-track or regular tickets depending on their heterogeneous waiting costs. At the park entrance, customers can choose tickets based on the observed congestion levels. Customers who purchase tickets in advance suffer from congestion uncertainty. Upgrading options allow customers to purchase regular tickets in advance and upgrade on-site i...

摘要：Problem definition: A company's project portfolio is an important success factor. Employing strategic buckets to segment the overall budget into budgets for different project types is a commonly used approach for managing project selection. Strategic buckets typically refer to sets of projects of a certain type, such as safe and risky projects. A strategic bucket specification defines the number of buckets and thresholds between them. This paper addresses the question of how different strategi...

摘要：Problem definition: We study a nurse staffing problem under random nurse demand and absenteeism. Although the demand uncertainty is exogenous, the absenteeism uncertainty is decision-dependent, that is, the number of nurses who show up for work partially depends on the nurse staffing level. For quality of care, hospitals develop float pools of hospital units and train nurses to be able to work in multiple units (termed cross-training) in response to potential nurse shortages. Methodology/resul...

摘要：Problem definition: We study how people with present bias make choices when they face multiple projects. Each project consists of a starting and a finishing stage, both requiring costly effort to complete but yield rewards only after project completion. Meth-odology/results: We derive people's perception-perfect strategies for project scheduling. Naifs may start a project, but never finish it. They may multitask; that is, start a new project before finishing an old project. They may not priori...

摘要：Problem definition: Distributionally robust optimization (DRO) is ubiquitous to address uncertainties inherent in operations management (OM) problems. Recently, an alternative goal-driven framework, robust satisficing (RS), is proposed. RS aims to attain a prescribed target, such as avoiding overshooting the cost budget, as much as possible under uncertainty. The goal-driven modeling philosophy fits many OM problems, yet there is a lack of direct comparisons between DRO and RS. In this paper, ...

摘要：Problem definition: The COVID-19 pandemic imposed unprecedented stresses on global supply chains (GSCs), compelling companies to reassess their supply chain structures and strategies. This crisis has also heightened awareness among businesses, consumers, and policymakers about the critical importance and far-reaching implications of GSC design and management. This unique moment presents a generational opportunity for Operations Management (OM) researchers to document and understand the ongoing...

摘要：Problem definition: This OM Forum article explores the barriers hindering the implementation of diversity, equity, and inclusion (DEI) programs in supply chains by analyzing the DEI performance of publicly traded and privately held companies. Whereas the importance of DEI in supply chain management is widely acknowledged, publicly traded and privately held companies exhibit a notable gap in achieving DEI goals. Methodology/results: This article explores the factors that enabled publicly traded...

摘要：Problem definition: Online retailers face the challenge of converting website traffic into actual purchases and profits. Specifically, the study examines how effective different forms of retargeting strategies are for engaging consumers who visit online stores but leave without making a purchase. Methodology/results: A field experiment was conducted to evaluate the impact of retargeting strategies offering free shipping (FSR) and free returns (FRR) on customer purchasing behavior and profitabi...
