• Private vs. Pooled Transportation: Customer Preference and Design of Green Transport Policy AI翻译
  作者：Arora, Kashish; Zheng, Fanyin; Girotra, Karan

  摘要：Problem definition: Large cities around the globe are facing an alarming growth in traffic congestion and greenhouse gas emissions, to which a significant contributor in recent years are on-demand cabs operated by ride-hailing platforms. Newly emerged pooled transportation options like shuttle services are cheaper and greener alternatives. However, those alternatives are still new to many customers and policy makers. The design of their promotion policies demands careful investigation. This pa...
• Scheduling Smarter: Scheduling Decision Impact on Nurse-Aide Turnover AI翻译

  摘要：Research problem: High turnover rates in long-term nursing facilities exacerbate the existing shortage of caregivers, a trend that will only worsen as the population of the United States ages. Part-time certified nursing assistants (CNAs) provide a significant amount of patient care in these facilities. CNAs also have high annual rates of turnover, which can harm health outcomes and increase the cost of care. In this study, we empirically analyze the effect of scheduling decisions on part-time...
• Multiproduct Dynamic Pricing with Limited Inventories Under a Cascade Click Model AI翻译

  摘要：Problem definition: Designing effective operational strategies requires a good understanding of customer behavior. The classic economic theory of customer choice has long been the paradigm in the operations literature. However, the rise of online marketplaces such as e-commerce has triggered considerable efforts in academia and industry to develop alternative models that not only provide a good approximation of customer behavior but also are easily scalable for large-scale implementations. In ...
• Should Gig Platforms Decentralize Dispute Resolution? AI翻译
  作者：Lee, Wee Kiat; Cui, Yao
  作者单位：Nanyang Technological University; Cornell University
  摘要：Problem definition: Disputes on online labor platforms have traditionally been mediated by the platform itself, which is often viewed as unhelpful or biased. However, there are emerging platforms that promise to resolve disputes with a novel tribunal system and relegate dispute resolution to individual platform users through a voting mechanism. We aim to examine the dispute resolution systems used by traditional platforms (i.e., the centralized dispute system) and emerging platforms (i.e., the...
• Agricultural Supply Chains in Emerging Markets: Competition and Cooperation Under Correlated Yields AI翻译
  作者：Li, Jian; Kouvelis, Panos; Dada, Maqbool
  作者单位：Northeastern Illinois University; Washington University (WUSTL); Johns Hopkins University
  摘要：Problem definition: We model the development of effective agricultural supply chains (agrichains) in emerging economies for better utilization of land and intermediate processing resources for harvested exportoriented goods. We study decisions made by farmers, intermediate processors, and government officials in agrichains. The structure and management of supply chains and government minimum guaranteed prices to farmers affect the performance of these chains and are in the domain of our study....
• Data-Driven Allocation of Preventive Care with Application to Diabetes Mellitus Type II AI翻译

  摘要：Problem definition: Increasing costs of healthcare highlight the importance of effective disease prevention. However, decision models for allocating preventive care are lacking. Methodology/results: In this paper, we develop a data-driven decision model for determining a cost-effective allocation of preventive treatments to patients at risk. Specifically, we combine counterfactual inference, machine learning, and optimization techniques to build a scalable decision model that can exploit high-...
• The Effect of Probabilistic Selling on Channel Dynamics in Supply Chains AI翻译
  作者：Fay, Scott; Gheibi, Shahryar
  作者单位：Syracuse University
  摘要：Problem definition: Probabilistic selling (PS) is a business model whereby, in addition to selling transparent products, a firm sells an opaque good, which is unknown to buyers until after purchase. We examine how PS affects retailer-manufacturer interactions in markets for physical goods and how upstream competition impacts channel members' incentives to facilitate PS. Methodology/results: Using a Hotelling-based model of a multiproduct retailer, we find that a retailer maximizes its profit b...
• A Branch-and-Price Algorithm Enhanced by Decision Diagrams for the Kidney Exchange Problem AI翻译
  作者：Riascos-Alvarez, Lizeth C.; Bodur, Merve; Aleman, Dionne M.
  作者单位：University of Toronto; University of Toronto; University of Toronto; University Health Network Toronto
  摘要：Problem definition: Kidney paired donation programs allow patients registered with an incompatible donor to receive a suitable kidney from another donor, as long as the latter's co-registered patient, if any, also receives a kidney from a different donor. The kidney exchange problem (KEP) aims to find an optimal collection of kidney exchanges taking the form of cycles and chains. Methodology/results: We develop the first decomposition method that is able to consider long cycles and long chains...
• In-Person or Virtual? What Will Operations Management/Research Conferences Look Like? AI翻译
  作者：Toscani, Antonio Cavallin; Atasu, Atalay; Van Wassenhove, Luk N.; Vinelli, Andrea
  作者单位：University of Padua; INSEAD Business School
  摘要：Problem definition: We examine the environmental implications of shifting from in-person to virtual conference formats and identify the effects of such a shift on the value conferences provide to our societies. We extend work from other fields to present a more comprehensive comparison of the environmental impact and perceived value of different conference formats for the operations management/research communities. Methodology/results: We leverage a series of COVID-19-induced natural experimen...
• Distributional Robustness and Inequity Mitigation in Disaster Preparedness of Humanitarian Operations AI翻译

  摘要：Problem definition: In this paper, we study a predisaster relief network design problem with uncertain demands. The aim is to determine the prepositioning and reallocation of relief supplies. Motivated by the call of the International Federation of Red Cross and Red Crescent Societies (IFRC) to leave no one behind, we consider three important practical aspects of humanitarian operations: shortages, equity, and uncertainty. Methodology/results: We first employ a form of robust satisficing measu...
