• Deep Policy Iteration with Integer Programming for Inventory Management AI翻译
  作者：Harsha, Pavithra; Jagmohan, Ashish; Kalagnanam, Jayant; Quanz, Brian; Singhvi, Divya

  摘要：Problem definition: In this paper, we present a reinforcement learning (RL)based framework for optimizing long-term discounted reward problems with large combinatorial action space and state dependent constraints. These characteristics are common to many operations management problems, for example, network inventory replenishment, where managers have to deal with uncertain demand, lost sales, and capacity constraints that results in more complex feasible action spaces. Our proposed programmabl...
• Offline Feature-Based Pricing Under Censored Demand: A Causal Inference Approach AI翻译

  摘要：Problem definition: We study a feature-based pricing problem with demand censoring in an offline, data-driven setting. In this problem, a firm is endowed with a finite amount of inventory and faces a random demand that is dependent on the offered price and the features (from products, customers, or both). Any unsatisfied demand that exceeds the inventory level is lost and unobservable. The firm does not know the demand function but has access to an offline data set consisting of quadruplets of...
• The Role of Route-Level Decisions in the Efficiency and Resilience of Airline Operations: Evidence from the Wright Amendment Repeal AI翻译

  摘要：Problem definition: We study the impact of an airline's route-level decisions on the efficiency and resilience of its operations. Methodology/results: Our study uses a proprietary passenger-level data set provided by Southwest Airlines and takes advantage of a regulatory change, the Wright Amendment repeal. The Wright Amendment restricted nonstop service between Dallas Love Field Airport (DAL) and most major destinations. Its repeal led to significant changes in Southwest's service offerings a...
• Budget Disclosure in Crowdfunding: Information Asymmetry and Cost Transparency AI翻译

  摘要：Problem definition: This paper investigates how a crowdfunding campaign's voluntary disclosure of sensitive cost information affects its funding performance on Kickstarter-a mainstream, primarily reward-based crowdfunding platform. Instead of enhancing a campaign's marketing traits, project budget as a novel information-provision tool reminds the crowd of the behind-the-scenes operations for developing and executing a project. This resembles the radical practice of cost transparency recently o...
• Laissez-Faire vs. Government Intervention: Implications of Regulation Preventing Nonauthorized Remanufacturing AI翻译
  作者：Esenduran, Gokce; Jin, Minyue; Zhou, Yu
  作者单位：Purdue University System; Purdue University; Chongqing University; Chongqing University
  摘要：Problem definition: In this paper, we compare laissez-faire and mandatory authorization policy regimes for third-party remanufacturing. Under a laissez-faire policy, an independent remanufacturer (IR) chooses whether to get the original equipment manufacturer (OEM) authorization. Under a mandatory authorization policy, the IR is required to get OEM authorization and to pay the OEM a fee for every item remanufactured. Motivated by China's regulatory journey that first mandated authorized remanu...
• Experience Minimizes the Pull-to-Center Effect in Newsvendor Decisions AI翻译
  作者：Brokesova, Zuzana; Deck, Cary; Peliova, Jana
  作者单位：University of Economics Bratislava; University of Alabama System; University of Alabama Tuscaloosa; Chapman University System; Chapman University
  摘要：Problem definition: The asymmetric pull-to-center effect for newsvendors is a robust finding in operations, and understanding why newsvendors make suboptimal decisions is key for identifying ways to improve decision-making quality in this critical task. Although prior studies have indicated that experience does not substantially mitigate the pull-to-center effect, the experience levels achieved in those previous studies are limited in comparison with the experience level that a near-continuous...
• Efficient Frontier and Applications in Product Offering and Pricing AI翻译
  作者：Ke, Chenxu; Lu, Lijian; Wang, Ruxian
  作者单位：Shanghai University of Finance & Economics; Hong Kong University of Science & Technology; Johns Hopkins University
  摘要：Problem definition: The joint assortment and pricing problem is notoriously difficult to solve, especially for large-scale issues subject to various operational constraints arising from business practices. In this paper, we delve into the joint optimization challenge under constrained logit choice models, accounting for product-differentiated price sensitivities across static, randomized, and dynamic contexts. Methodology/results: We develop a unified optimization methodology that applies effi...
• Efficient Cloud Server Deployment Under Demand Uncertainty AI翻译
  作者：Liu, Rui Peng; Mellou, Konstantina; Gong, Evelyn Xiao-Yue; Li, Beibin; Coffee, Thomas; Pathuri, Jeevan; Simchi-Levi, David; Menache, Ishai

  摘要：Problem definition: Cloud computing is a multibillion-dollar business that draws substantial capital investments from large companies such as Amazon, Microsoft, and Google. Large cloud providers need to accommodate the growing demand for computing resources while avoiding unnecessary overprovisioning of hardware and operational costs. The underlying decision processes are challenging, as they involve long-term hardware and infrastructure investments under future demand uncertainty. In this pap...
• Going the Distance: The Impact of Commute on Gender Diversity in Public Service AI翻译
  作者：Kaaua, Dawson; Virudachalam, Vanitha
  作者单位：Georgetown University; University of Illinois System; University of Illinois Urbana-Champaign
  摘要：Problem definition: Women have been shown to prefer jobs with a better work-life balance across many fields. Given that serving as a state political representative requires a significant amount of travel between one's home district and the state capitol, this suggests that long commute distances may reduce the number of women seeking political office in the United States. At the same time, state political positions vary in their degree of flexibility (e.g., full-time versus part-time) and comm...
• Multi-Armed Bandits with Endogenous Learning Curves: An Application to Split Liver Transplantation AI翻译
  作者：Tang, Yanhan (Savannah); Li, Andrew; Scheller-Wolf, Alan; Tayur, Sridhar
  作者单位：Southern Methodist University; Carnegie Mellon University
  摘要：Problem Definition: Proficiency in many sophisticated tasks is attained through experience-based learning, in other words, learning by doing. For example, transplant centers' surgical teams need to practice difficult surgeries to master the skills required. Meanwhile, this experience-based learning may affect other stakeholders, such as patients eligible for transplant surgeries, and require resources, including scarce organs and continual efforts. To ensure that patients have excellent outcom...
