  摘要：Problem definition: During pandemics, policymakers must make critical decisions about public health interventions and allocations of scarce resources in response to rapidly evolving diseases under high levels of uncertainty. Epidemiological models, such as the Susceptible-Exposed-Infectious-Recovered-type (SEIR-type) compartmental model, are indispensable tools for predicting how a pandemic may spread over time and how different public health interventions could affect the outcome. Based on su...
• Endogenous Commitments: Implications for Supply Chains AI翻译
  作者：Singh, Narendra
  作者单位：Nazarbayev University
  摘要：Problem definition: Although a centralized firm selling durable products benefits from committing to future prices, it remains unclear whether this conclusion extends to a decentralized supply chain where a manufacturer distributes durable products through a retailer. Further, previous research on commitments in decentralized supply chains is sparse and assumes exogenous commitments. To address this gap, we examine the implications of commitment decisions in a supply chain where a manufacturer...
• When to Push Ads: Optimal Mobile Ad Campaign Strategy Under Markov Customer Dynamics AI翻译

  摘要：Problem definition: We investigate a seller's optimal advertising strategy targeting customers who interact with the seller over time. We model each customer's engagement by a continuous-time (hidden) Markov chain with two states: active and inactive. While in the active state, customers make purchases according to a Poisson process; in contrast, customers in the inactive state make no purchases. The seller can use advertisements to activate customers and the activation probability may be affe...
• Trade Credit with Costly Sales Revenue Verification AI翻译

  摘要：Problem definition: Trade credit is a common mechanism for financing retail inventories. A supplier who offers trade credit may not observe sales revenue and verification is costly. When a retailer offers to pay less than the full loan amount, the supplier may either accept the offered amount or initiate verification. We investigate the impact of costly sales revenue verification on the equilibrium wholesale price and loan limit, with the goal of determining whether the supplier's profit is gr...
• Forced Labor in Labor Supply Chains: Contracting and Information Asymmetry AI翻译
  作者：Papier, Felix; Tang, Christopher; Parappathodi, Javaiz

  摘要：Problem definition: We examine how market and economic factors influence the occurrence of forced labor in supply chains and how buying companies can develop optimal contracts to prevent forced labor in the presence of information asymmetry between the buyer and the agent. Methodology/results: We develop a game-theoretic model of a labor supply chain comprising a socially aware buyer and a profit-maximizing labor agent. Our equilibrium analysis shows that the audit cost affects the extent to w...
• Tides Need STEMMED: A Locally Operating Spatiotemporal Mutually Exciting Point Process with Dynamic Network for Improving Opioid Overdose Death Prediction AI翻译

  摘要：Problem definition: Efforts to mitigate the U.S. opioid crisis have been complicated by ever-changing trends in opioid overdose deaths (OODs) across communities and drug types. Public health surveillance efforts are hampered by these challenges, making prediction of local OOD trends and coordination across communities critical. In this research, we design a model-based public health surveillance system capable of leveraging implicit connections between past and future OODs, thereby operating a...
• Scope Contracts to Coordinate Assortment Planning in Omnichannel Retail Supply Chains AI翻译
  作者：Aslani, Amin; Alp, Osman
  作者单位：University of Wisconsin System; University of Calgary
  摘要：Problem definition: Omnichannel retail systems consist of online sales channels and physical stores. We consider a decentralized omnichannel retail supply chain (ORSC), where the online channel is the manufacturer's sales platform and the physical store is an independent retailer selling the manufacturer's products. The assortment showcased by the retailer in its store affects sales and potential product returns for both sales channels because customers can over-or undervalue the products that...
• Artificial Intelligence, Emotional Labor, and Service Operations AI翻译

  摘要：Problem definition: Emotional labor is increasingly demanded in service operations, placing tremendous psychological strain on human employees and posing challenges to scalability and sustainability. Our study scrutinizes whether artificial intelligence (AI) service bots may tackle these challenges by examining how and when AI's engagement in emotional labor enhances economic performance in service operations. Methodology/results: We provide causal evidence from a pair of randomized field expe...
• Order Ahead for Pickup: Promise or Peril? AI翻译
  作者：Sun, Ke; Liu, Yunan; Yang, Luyi
  作者单位：McGill University; Koc University; North Carolina State University; University of California System; University of California Berkeley
  摘要：Problem definition: Mobile technologies have increasingly enabled remote customers to order ahead at quick-service restaurants. As customers travel to the service facility to pick up their orders, their orders also advance in the food preparation queue. It is widely believed that the ability to order ahead reduces customers' total delay and, therefore, allows restaurants to attract more orders and achieve higher throughput than if customers must order onsite. Methodology/results: We build a qu...
• Impacts of Care Provider Collaborations on the Service Time for Inpatient Stays: An Analysis Using Electronic Health Record Audit Logs and Dynamic Graphs AI翻译

  摘要：Problem definition: Collaboration among care providers is critical to healthcare delivery, yet its impact on inpatient service times-especially at the interpersonnel level- remains unclear. Prior work has focused on team familiarity or shared experience. In contrast, we examine collaboration, which is defined as real-time coactivity during an inpatient stay. This study explores the nonlinear effects of collaboration on service time, focusing on weak initial collaboration, strengthening dynamic...
