摘要：This paper proposes a framework for learning customer preferences and optimizing e-commerce assortments, focusing on intra-category multi-choice behavior, where customers buy multiple items within the same category. Unlike traditional discrete choice models (DCMs) that assume single-product purchases, e-commerce data show frequent intra-category multiproduct purchases, especially during promotions. To capture this, we introduce the multi-choice rank list model (MC-RLM), which accounts for both...

摘要：We investigate the fleet repositioning problem aimed at dynamically optimizing vehicle distributions to maximize long-run average social welfare in a vehicle-sharing system. We model the problem as a Markov decision process under the ex ante committed decision scheme, characterizing the balanced myopic policy as optimal for the average reward setting. This policy efficiently aligns vehicle supply with trip demand and mitigates the curse of dimensionality, enhancing computational efficiency sig...

摘要：The crowdfunding market has developed fast in recent years. However, the problem of information asymmetry is still an issue for both backers and fundraisers. Hence, crowdfunding platforms design various policies to reveal more project information to backers. This paper studies the impact of product sampling, a novel policy in the crowdfunding market, and provides suggestive evidence of the underlying mechanism. A product sampling campaign can be divided into three stages chronologically. In Ap...

摘要：Federal agencies use reverse auctions to procure cloud infrastructure services offered by major public cloud providers such as Amazon, Google, and Microsoft. Although recent research has examined operational issues in cloud computing, these papers have not analyzed the vendor base design decisions when these cloud capacity instances are procured through the reverse auction mechanism. Therefore, several important research questions are still unaddressed. For example, how should federal clients ...

摘要：The COVID-19 crisis has starkly highlighted the vulnerability of businesses and underscored the critical importance of organizational resilience. Firms across multiple sectors-particularly non-essential businesses-have suffered a heavy blow during the height of the pandemic. Guided by the resource dependence theory and using a proprietary and rich dataset from a leading online-to-offline platform for medical aesthetics services-a typical type of non-essential business-we find that the pandemic...

摘要：National culture plays a vital role in shaping operations management (OM) practices, yet its impact remains largely underexplored. This paper builds on the Gupta and Gupta's cross-cultural OM research framework that consists of three categories: operational decisions, supply chain management, and interdisciplinary topics. It highlights how national culture influences key areas such as product return policies, dynamic operations complexity, and buyer-supplier conflict management in cross-cultur...

摘要：Scoring systems, as a type of predictive model, have significant advantages in interpretability and transparency and facilitate quick decision-making. As such, scoring systems have been extensively used in a wide variety of industries, such as healthcare and criminal justice. However, the fairness issues in these models have long been criticized, and the use of big data and machine learning (ML) algorithms in the construction of scoring systems heightens this concern. This article proposes a g...

摘要：How to decarbonize transportation, which is now, unfortunately, the largest source of carbon emissions among all sectors? The entire industry is heavily driven by economies of scale. When more freight is collected in a lane, it can be shifted to a greener transport mode (e.g., from less-than-truckload to full-truckload, and further to rail transport), and costs and emissions are saved. To support firms achieving such benefits, we develop novel supply chain contracting models that capture suppl...

摘要：Despite increasing investments in Environmental, Social, and Governance (ESG) initiatives and practices, firms often fail to meet public expectations, causing ESG incidents. While firms often choose to remain silent after an incident, we argue that this is not attractive to firms anymore on social media platforms, where consumers and stakeholders can freely share information and concerns. That is, firms tend to use official social media accounts to increase communication frequency and communic...
