• Precommitments in Two-Sided Market Competition AI翻译
  作者：Hu, Ming; Liu, Yan
  作者单位：University of Toronto; Hong Kong Polytechnic University
  摘要：Problem definition: We consider a two-sided market competition problem where two platforms, such as Uber and Lyft, compete on both supply and demand sides and study the impact of precommitments in a variety of practically motivated instruments on the equilibrium outcomes. Academic/practical relevance: We extend a set of classic oligopoly pricing results to account for two-sided competition under demand uncertainty. Methodology: We investigate multi-stage competition games. Results: We start wi...
• Revenue Management in Crowdfunding AI翻译
  作者：Zhang, Jiding; Savin, Sergei; Veeraraghavan, Senthil

  摘要：Problem definition: We study the optimal design of crowdfunding campaigns and develop a model that maximizes revenue for a given crowdfunding campaign by optimizing both the pledge level sought from donors and the duration of the campaign. Academic/practical relevance: Our model explains the patterns of backer/donor arrival and pledging observed on crowdfunding platforms, such as Kickstarter. This model can be used to calibrate the revenue impact from using prespecified pledge levels or campai...
• Robust Inventory Management: A Cycle-Based Approach AI翻译
  作者：Chen, Yupeng; Iyengar, Garud; Wang, Chun
  作者单位：Nanyang Technological University; Columbia University; Tsinghua University
  摘要：Problem definition: We study the robust formulation of an inventory model with positive fixed ordering costs, where the unfulfilled demand is either backlogged or lost, the lead time is allowed to be positive, the demand is potentially intertemporally correlated, and the information about the demand distribution is limited. Methodology/results: We propose a robust cycle-based policy that manages inventory by dividing the planning horizon into nonoverlapping inventory cycles, where an order is ...
• Signaling Service Quality Through Queue Disclosure AI翻译

  摘要：Problem definition: We consider a single-server queueing system where service quality is either high or low. The server, who knows its exact quality level, can signal this quality information to customers by revealing or concealing its queue length. Based on this queue disclosure action and the observed queue length in the case of a revealed queue, customers decide whether to join the system. Academic/practical relevance: The queue disclosure action is regarded as a signal indicating the servi...
• On-Demand Delivery from Stores: Dynamic Dispatching and Routing with Random Demand AI翻译
  作者：Liu, Sheng; Luo, Zhixing
  作者单位：University of Toronto; Nanjing University
  摘要：Problem definition: On-demand delivery has become increasingly popular around the world. Motivated by a large grocery chain store who offers fast on-demand delivery services, we model and solve a stochastic dynamic driver dispatching and routing problem for last-mile delivery systems where on-time performance is the main target. The system operator needs to dispatch a set of drivers and specify their delivery routes facing random demand that arrives over a fixed number of periods. The resultin...
• Flexibility and Consistency in Long-Term Care Rostering AI翻译
  作者：Slaugh, Vincent W.; Scheller-Wolf, Alan A.
  作者单位：Cornell University; Carnegie Mellon University
  摘要：Problem definition: We consider the rostering decisions-that is, the assignment of workers scheduled for a shift to units-of a long-term care facility. The facility's objective is to minimize the monthly inconsistency level, a widely promoted quality metric representing the number of different caregivers working in each unit over one month. Methodology/results: We introduce simple rostering heuristics that prioritize either parttime or full-time workers and present a stochastic model of the re...
• State-Dependent Estimation of Delay Distributions in Fork-Join Networks AI翻译
  作者：Carmeli, Nitzan; Yom-Tov, Galit B.; Boxma, Onno J.
  作者单位：Technion Israel Institute of Technology
  摘要：Problem definition: Delay announcements have become an essential tool in service system operations: They influence customer behavior and network efficiency. Most current delay announcement methods are designed for relatively simple environments with a single service station or stations in tandem. However, complex service systems, such as healthcare systems, often have fork-join (FJ) structures. Such systems usually suffer from long delays as a result of both resource scarcity and process synch...
• COVID-19: Prediction, Prevalence, and the Operations of Vaccine Allocation AI翻译

  摘要：Problem definition: Mitigating the COVID-19 pandemic poses a series of unprecedented challenges, including predicting new cases and deaths, understanding true prevalence beyond what tests are able to detect, and allocating different vaccines across various regions. In this paper, we describe our efforts to tackle these issues and explore the impact on combating the pandemic in terms of case and death prediction, true prevalence, and fair vaccine distribution. Methodology/results: We present th...
• Impacts of Distributive Comparison Behavior on Corporate Social Responsibility in Supply Chains: The Role of Small Firms AI翻译
  作者：Wang, Mingzheng; Fang, Xin; Wang, Zizhuo; Chen, Ying-ju
  作者单位：Zhejiang University; Singapore Management University; Hong Kong University of Science & Technology
  摘要：Problem definition: In this paper, we explore how a firm's concern about profit distribution and the size of downstream firms in supply chains affect corporate social responsibility (CSR) investment strategy. Methodology/results: In a supply chain consisting of one supplier and one manufacturer, both players decide whether to invest to reduce CSR violations, and they negotiate over a wholesale price. Distributive comparison behavior makes the manufacturer compare the profit with his equitable ...
• A Markov Decision Model for Managing Display-Advertising Campaigns AI翻译
  作者：Agrawal, Narendra; Najafi-Asadolahi, Sami; Smith, Stephen A.
  作者单位：Santa Clara University
  摘要：Problem definition: Managers in ad agencies are responsible for delivering digital ads to viewers on behalf of advertisers, subject to the terms specified in the ad campaigns. They need to develop bidding policies to obtain viewers on an ad exchange and allocate them to the campaigns to maximize the agency's profits, subject to the goals of the ad campaigns. Academic/practical relevance: Determining a rigorous solution methodology is complicated by uncertainties in the arrival rates of viewers...
