摘要:Problem definition: Responding to large hurricanes requires the deployment of food, shelter, and medical assistance to relieve the immediate needs of the victims. These services are supported by, and eventually fully transitioned to, local resources, such as grocery stores. However, disparities in local infrastructure and services may result in lowincome communities bearing a disproportionate burden from these disasters. We investigate this possibility by testing for differences in the percent...

摘要:Problem definition: The opioid crisis has been called the worst drug crisis in American history. Although myriad factors influencing this crisis have been examined, the questions of whether and how the diversion of prescription (Rx) opioids from legal supply chain channels to illegal marketplaces contributes to the ongoing crisis remain understudied. Methodology/results: We utilize the enactment of the Drug Supply Chain Security Act (DSCSA) and cross-state variations in initial Rx opioid seizu...

摘要:Problem definition: This paper explores budget allocation strategies for a multichannel ad campaign, where a marketing agency strives to maximize the total conversions by dynamically adjusting budget allocation over marketing channels. A salient feature of the problem is the interplay of spillover and carryover effects; namely, customers are exposed to ads through multiple channels, and thus ads from one channel affect the effectiveness of the subsequent ads from other channels. Methodology/re...

摘要:Problem definition: Managers in digital ad agencies face the complex problem of setting prices for new ad campaigns, bidding for viewers on ad exchanges, and allocating them appropriately to campaigns. We have developed an analytical methodology for optimizing the agency's profits, with uncertainties in the arrival of potential viewers and new ad campaigns and in winning bids and obtaining viewer actions on ad exchanges. Methodology/results: The ad agency manages a series of contracts with adv...

摘要:Problem definition: Behavioral health interventions, delivered through digital platforms, have the potential to significantly improve health outcomes through education, motivation, reminders, and outreach. We study the problem of optimizing personalized interventions for patients to maximize a long-term outcome, in which interventions are costly and capacity constrained. We assume we have access to a historical data set collected from an initial pilot study. Methodology/results: We present a n...

摘要:Problem definition: This paper addresses an appointment scheduling problem involving multiple sequential servers using a distributionally robust optimization (DRO) approach. Two decisions are optimized: the schedule for patient visits and an adjusting policy to rebalance customers' waiting time across servers. Methodology/results: We formulate the distributionally robust appointment scheduling problem in sequential-servers systems using conic optimization, incorporating service time correlatio...

摘要:Problem definition: The configuration of an emergency vehicle fleet (EVF) is critical to ensure that responders have the resources necessary to serve emergencies quickly and help prevent loss of life and property. Determining the fleet's optimal design involves decisions regarding its size, the spatial distribution of the stations, and the extent of collaboration among them. We study the optimal design of a fire service fleet that is characterized by low utilization of the vehicles. The primar...

摘要:Problem definition: Motivated by technological advances in real-time data collection about customers location in service systems, we study the effect of partial visibility of customers on waiting time prediction. We consider systems where the predictor observes only a subset of the customers interacting with the system while serving all customers indiscriminately. Methodology/results: We formulate a novel model of a partially visible queue and analyze the waiting time prediction problem, deriv...

摘要:Problem definition: Short video format platforms like NetEase and TikTok are attention economies that host user-generated content, in the form of combined video and audio elements, and operate on principles of network virality. This study explores user content creation strategies by focusing on decisions around content release frequency and the incorporation of adopted content in newly generated creations. Methodology/results: We theoretically explore the role of the following three mechanisms...

摘要:Problem definition: Large language models (LLMs) are being increasingly leveraged in business and consumer decision-making processes. Because LLMs learn from human data and feedback, which can be biased, determining whether LLMs exhibit human-like behavioral decision biases (e.g., neglect, risk aversion, confirmation bias, etc.) is crucial prior to implementing LLMs into decision-making contexts and workflows. To understand this, we examine 18 common human biases that are important in operatio...
