摘要：The coronavirus disease 2019 (COVID-19) pandemic led to sharp declines in public transit ridership, resulting in budget shortfalls and service cuts that disproportionately affect vulnerable riders who lack alternative transportation options. Understanding the effect of vaccination on public transportation demand is important for planning for demand recovery as vaccination efforts progress. This study examines this effect, with a particular focus on heterogeneous effects across population group...

摘要：In the competitive landscape of modern business, tacit knowledge (TK) sharing has emerged as a critical enabler of innovation and transformation, particularly within the realm of operations management. In this context, the efficient flow of TK is essential for optimizing processes, promoting technology development, and sustaining competitive advantage. While the role of workplace friendship in facilitating TK sharing has been well-documented, there is a common misconception that close personal...

摘要：Order splitting is one of the key issues in the e-commerce order fulfillment process. It increases operational costs, elevates carbon emissions, and compromises customer satisfaction. This article focuses on determining the product assortments to store within the multi-warehouse logistics network to minimize the total number of split orders subject to cardinality constraints. We show that this minimizing split orders (MSO) problem is NP-hard and demonstrate that even finding an optimal order f...

摘要：Spatial unfairness in spatiotemporal forecasting tasks can lead to critical issues, for example, inefficient resource allocation during pandemics or air pollution crises, exacerbating the spread of diseases or increasing exposure to pollution. The existing fair forecasting methods often struggle with spatiotemporal data that lack clear sensitive attributes and exhibit dynamic complexity. A pseudogrouping adversarial machine learning method that combines a spatiotemporal clustering-based pseudo...

摘要：Facilitated by information technology and online platforms, group service has emerged in many service systems, such as one-to-many tour guide service, one-to-many tutoring courses and one-to-many medical diagnosis. We consider a service provider offering both group service and individual service and model it as a single-server queue in which customers with heterogeneous waiting costs make both joining/balking and group/individual service decisions. We solve the private provider's service assor...

摘要：We combine insights from information processing theory (IPT), supply chain resilience literature, and collaboration with a leading supply chain planning technology provider to study the effects of excess inventory (a buffering tactic) and usage of supply chain planning systems (SCPSs) (a bridging technology) on supply chain resilience. Utilizing the exogenous disruptions caused by the COVID-19 pandemic as the setting for quasi-natural experiments, we compare profit impact and time-to-recover a...

摘要：Automotive manufacturers have been under intense pressure to improve the fuel efficiency, or miles per gallon (MPG), of their internal combustion engine (ICE) vehicles. Research that explores hidden costs of continuing to push the limits of ICE MPG is sparse. We analyze the relationship between the MPG of 643 unique model-engines produced and sold by 18 manufacturers over an 18-year period and 19,785 vehicle safety defects reported to the National Highway Traffic Safety Administration (NHTSA)....

摘要：Dockless bike sharing has been widely recognized for its potential environmental benefits by bridging the last-mile gap and encouraging a shift toward greener modes of travel. However, these benefits depend on large-scale bike adoption rather than mere service presence. Unfortunately, this adoption is often undermined by limited bike supply or unfavorable operating contexts. Leveraging the staggered rollout of Ofo and Mobike across Chinese cities, we employ a quasi-experimental stacked differe...

摘要：Student evaluations of teaching are widely used in higher education operations to assess instructional quality and inform personnel decisions, yet they remain vulnerable to systematic bias. This study examines whether the rapid transition to online education during COVID-19 changed perceived teaching effectiveness across instructors from different race-gender groups. Using 598,252 student evaluations from the top 150 U.S. universities, we estimate a difference-in-differences model with propens...

摘要：This study examines the composition of attributes among members of the Production and Operations Management Society (POMS). We analyze POMS membership data from 2017 to 2023 and conference registration data from 2011 to 2024. Specifically, the study seeks to: (1) describe the current composition of POMS members and conference registrants in terms of gender, academic rank, and country of affiliation, and (2) provide recommendations for improving representation within professional societies.
