• Data Set-Spatiotemporal Bikeshare System Status AI翻译
  作者：Byrd, Eleanor; Parker, Chris; Balasubramanian, Karthik
  作者单位：University of Virginia; University of Virginia; Howard University
  摘要：Problem definition: Bikeshare systems are expanding worldwide, but empirical research is hindered by the lack of high-frequency data on system status. Public bikeshare data sets typically include only trip start and end records, with no information on real-time station conditions (e.g., how many bikes or docks are available). This gap in data limits the analysis of operational performance and user service levels in bikeshare systems. Methodology/results: We address this gap by collecting nearl...
• Keep the Water Flowing: The Hidden Crisis of Rural Water Management AI翻译

  摘要：Problem definition: In rural sub-Saharan Africa, people rely on communal hand pumps for clean drinking water. These hand pumps frequently break down and require repairs. Operating under the assumption that preventive maintenance is too expensive, local nongovernmental organizations (NGOs) often face difficult decisions about where to allocate their limited resources to reduce water point downtime. NGOs could invest in gathering more functionality information so that they can use their scarce r...
• Multiproduct Inventory Systems with Upgrading: Replenishment, Allocation, and Online Learning AI翻译
  作者：Tang, Jingwen; Duenyas, Izak; Shi, Cong; Yang, Nan
  作者单位：University of Miami; University of Michigan System; University of Michigan
  摘要：Problem definition: We consider the joint optimization of ordering and upgrading decisions in a dynamic multiproduct system over a finite horizon of T periods. In each period, multiple types of demand arrive stochastically and can be satisfied either with supply of the same type or by upgrading to a higher-quality product. The goal is to find an optimal joint replenishment and allocation policy that maximizes total expected profit, both when the firm knows the demand distributions a priori and...
• On Designing a Fire Emergency Vehicle Fleet AI翻译
  作者：Luzon, Yossi; Baron, Opher; Verter, Vedat; Berman, Oded
  作者单位：University of Toronto; Queens University - Canada; Hebrew University of Jerusalem
  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...
• Waiting Time Prediction with Invisible Customers AI翻译

  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...
• Frame by Fame: Content Creation on Short Video-Format Platforms AI翻译
  作者：Deshmane, Abhishek; Barriola, Xabier
  作者单位：University System of Georgia; Georgia Institute of Technology; Tilburg University
  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...
• A Manager and an AI Walk into a Bar: Does ChatGPT Make Biased Decisions Like We Do? AI翻译

  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...
• Data-Driven Pricing for Availability-Based Upgrades Under a Multiple Binary Choice Model with Copula AI翻译
  作者：Yilmaz, Ovunc; Ekbatani, Farbod; Zhao, Zifeng; Wang, Ruxian; Vakhutinsky, Andrew
  作者单位：University of Colorado System; University of Colorado Boulder; University of Chicago; University of Notre Dame; Johns Hopkins University
  摘要：Problem definition: Intense competition in the travel industry has increasingly shifted focus toward ancillary services, particularly seat upgrades in airlines and room upgrades in hotels. In response to this trend, several innovative solutions have emerged, among which Nor1's eStandby Upgrade program stands out by offering discounted, availability-based room upgrades. Revenue management for these upgrades is complex because customers may request multiple upgrades, whereas hotels allocate them...
• Multioutput Extreme Spatial Model for Complex Aircraft Production Systems AI翻译
  作者：Lee, Cheolhei; Wang, Xing; Yue, Xiaowei; Wu, Jianguo
  作者单位：Virginia Polytechnic Institute & State University; Illinois State University; Tsinghua University; Peking University
  摘要：Problem definition: Data-driven models in machine learning have enabled efficient management of production systems. However, a majority of machine learning models are devoted to modeling the mean response or average pattern, and this is inappropriate for studying abnormal extreme events that are often of primary interest in aircraft manufacturing. Because extreme events from heavy-tailed distributions give rise to prohibitive expenditures in system management, sophisticated extreme models are ...
• Frontiers in Operations: Prioritizing Disaster Recovery Under Budget Uncertainty AI翻译

  摘要：Problem definition: In the aftermath of disasters, governments must make urgent decisions about how to deploy limited resources for recovery, such as restoring roads or siting emergency facilities. However, these actions often need to be taken before the amount and timing of external funding (e.g., federal disaster relief) are known. This mismatch between the need for immediacy and the delay in budget realization poses a fundamental challenge: How can agencies prioritize recovery actions when ...
