  摘要：Consider a public healthcare system consisting of a hospital, a mobile clinic (MC), and a population of potential patients. The government is concerned about the system's healthcare spending and the population's health outcomes. It decides the frequency and capacity of the MC service to maximize the social welfare that consists of two terms: the system's long-run average healthcare cost and the population's average quality-adjusted life year (QALY). We characterize the population's natural dis...
• Effectiveness of Online Education During the COVID-19 Pandemic: Evidence from Chinese Universities AI翻译

  摘要：The COVID-19 pandemic triggered a global shift from face-to-face instruction to online learning, posing new operational challenges for business schools, particularly in equipping students with quantitative skills essential for the labor market. Leveraging China's abrupt lockdown policies as a natural experiment, we examine the heterogeneous effects of online education on student academic performance. Using a panel dataset of 15,329 observations from 7,867 undergraduate students across nine Chi...
• Joint Shelf Design and Space Planning Problem With Placement Options AI翻译
  作者：Zajac, Sandra; Kuhn, Heinrich
  摘要：This article introduces the first joint shelf design and space planning problem that considers two placement options for items-hanging and shelving-on flexible shelves. These types of shelves are used in sectors such as do-it-yourself and toy retail, and for household goods in grocery stores. However, they have received limited attention in the literature, which typically focuses on regular shelves with a single placement option: placing items on shelf panels. The problem requires three interd...
• Assortment Optimization in the Presence of Focal Effect: Operational Insights and Efficient Algorithms AI翻译

  摘要：The assortment provided by the seller can influence customers' evaluation of item utility. A possible consequence is that certain items in an assortment become focal items to customers, and customers over-evaluate their utilities. We refer to this phenomenon as the focal effect. Kovach and Tserenjigmid (2022) recently propose a focal Luce model (FLM) to describe customers' choices in the presence of the focal effect. The merit of the FLM lies in its flexibility to model different consumer psyc...

  摘要：In the last decade and recently, a wide range of industries and organizations have been subject to IT-related security threats and cybersecurity breaches of varying degrees of severity at an alarming rate. A common practice adopted by organizations to ensure system and network security is to conduct regular audits and assessments. This paper takes on an organizational strategy perspective to analytically model the cost impact of random breaches in various types of networks subject to different...
• Wheels on the Bus: Impact of Vaccine Rollouts on Demand for Public Transportation AI翻译

  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...
• Fragile Interpersonal Relationship in Tacit Knowledge Sharing: How Workplace Friendship Fails Under Competition and Functional Similarity AI翻译
  作者：Wu, Chunlin; Hu, Xiao; Guo, Xuanhao; Ning, Xin; Hui, Chun

  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...
• Multi-Warehouse Assortment Selection: Minimizing Order Splitting in E-Commerce Logistics AI翻译

  作者单位：Chinese Academy of Sciences; University of Science & Technology of China, CAS; National University of Singapore; Durham University
  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...
• Improving the Spatial Fairness of Spatiotemporal Sequence Forecasting Service Systems AI翻译
  作者：Xue, Gang; Ren, Long; Yan, Xiaojie; Cui, Ziruo; Gong, Daqing; Chen, Jian
  作者单位：Beijing Jiaotong University; Tsinghua University; University of International Business & Economics; Tsinghua University
  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：The decarbonization of power systems facilitates the electrification of appliances, many of which can be operated in a flexible way. Demand response (DR) programs can exploit this flexibility with retail price adjustment, thereby addressing several operational challenges. In this paper, we address the welfare optimization problem of local utilities that procure electricity for their customers at the wholesale market. We demonstrate how DR programs can be designed for local electricity systems ...
