• A Deep Q-Network for the Beer Game: Deep Reinforcement Learning for Inventory Optimization AI翻译
  作者：Oroojiooyjadid, Afshin; Nazari, MohammadReza; Snyder, Lawrence, V; Takac, Martin
  作者单位：Lehigh University
  摘要：Problem definition: The beer game is widely used in supply chain management classes to demonstrate the bullwhip effect and the importance of supply chain coordination. The game is a decentralized, multiagent, cooperative problem that can be modeled as a serial supply chain network in which agents choose order quantities while cooperatively attempting to minimize the network's total cost, although each agent only observes local information. Academiclpractical relevance: Under some conditions, a...
• Optimal Intervention Policies for Total Joint Replacement Postoperative Care Process AI翻译

  摘要：Problem definition: Successful outcomes of total joint replacement (TJR) depend not only on the surgery but also on the patients' postsurgical behaviors; inadequate postsurgical performance can lead to complications and/or readmissions. To prevent such events, patients go through postoperative intervention processes in which they receive physical therapy and/or some form of rehabilitative services. Although the costs of providing such interventions and readmission penalties are substantial, no...
• Introducing Autonomous Vehicles: Adoption Patterns and Impacts on Social Welfare AI翻译
  作者：Baron, Opher; Berman, Oded; Nourinejad, Mehdi
  作者单位：University of Toronto; York University - Canada
  摘要：Problem definition: Autonomous vehicles (AVs) are predicted to enter the consumer market in less than a decade. There is currently no consensus on whether their presence will have a positive impact on users and society. The skeptics of automation foresee increased congestion, whereas the advocates envision smoother traffic with shorter travel times. We study the automation controversy and advise policymakers on how and when to promote AVs. Academic/practical relevance: The AV technology is adv...
• A Responsive-Pricing Retailer Sourcing from Competing Suppliers Facing Disruptions AI翻译

  摘要：Problem definition: We study a problem of a retailer that orders from competing strategic suppliers subject to independent or correlated disruptions and responds by setting the retail price on delivery, called responsive pricing. The suppliers set their wholesale prices in a Nash game. Academic/practical relevance: Supplier disruption correlation exists for reasons such as product and service designs, geographic proximity, and common tier 2 suppliers. In practice, many retailers are able to se...
• Product Price, Quality, and Service Decisions Under Consumer Choice Models AI翻译
  作者：Wang, Ruxian; Ke, Chenxu; Cui, Shiliang
  作者单位：Johns Hopkins University; Nanjing University; Georgetown University
  摘要：Problem definition: In this paper, we develop an integrated framework to study a firm's joint decisions on product price, quality, and service duration in a variety of monopolistic and competitive scenarios. Academiclpractical relevance: Product price, quality, and ancillary service (such as maintenance and factory warranty) are arguably among the most important factors consumers consider when making a purchase decision. Meanwhile, they are also seen as effective instruments for firms to achie...
• Strategic Inventories Under Supply Chain Competition AI翻译
  作者：Li, Xi; Li, Yanzhi; Chen, Ying-Ju

  摘要：Problem definition: We consider the effects of strategic inventory (SI) in the presence of chain-to-chain competition in a two-period model. Academic/practical relevance: Established findings suggest that SI may alleviate double marginalization and improve the efficiency of a decentralized distribution channel. However, no studies consider the role of SI under chain-to-chain competition. Methodology: We build a two-period model consisting of two competing supply chains, each with an upstream m...
• Procurement Strategies with Unreliable Suppliers Under Correlated Random Yields AI翻译
  作者：Dong, Lingxiu; Geng, Xln; Xiao, Guang; Yang, Nan
  作者单位：Washington University (WUSTL); University of Miami; Hong Kong Polytechnic University
  摘要：Problem definition: This paper studies the sourcing of a monopoly firm that procures from multiple unreliable suppliers to meet its deterministic/price-dependent demand. The suppliers' production processes are unreliable and are modeled by correlated proportional random yields. Academic/practical relevance: As a proactive risk-mitigation tool, supply diversification has been widely studied in the literature, with the primary focus on independent supply risks. However, supply risks in practice ...
• Surge Pricing and Two-Sided Temporal Responses in Ride Hailing AI翻译
  作者：Hu, Bin; Hu, Ming; Zhu, Han
  作者单位：University of Texas System; University of Texas Dallas; University of Toronto; Dongbei University of Finance & Economics
  摘要：Problem definition: We investigate surge pricing in ride-hailing platforms from a temporal perspective, highlighting strategic behavior by riders and drivers and that drivers respond to surge pricing much more slowly than riders do. Academic/practical relevance: Surge pricing in ride-hailing platforms is a pivotal and controversial subject. Despite abundant anecdotal evidence, strategic behavior by riders and drivers has not been formally studied in the literature. Methodology: We adopt and an...
• A Two-Sided Incentive Program for Coordinating the Influenza Vaccine Supply Chain AI翻译
  作者：Arifoglu, Kenan; Tang, Christopher S.
  作者单位：University of London; University College London; University of California System; University of California Los Angeles
  摘要：Problem definition: The U.S. influenza (flu) vaccine supply chain is decentralized and experiences frequent supply and demand mismatches caused by two key factors: (1) the vaccine production process (yield) is highly uncertain; and (2) individuals are self-interested and do not completely take into account positive and negative externalities that they impose on others. To improve matching of supply and demand, we counteract these factors by developing an ex ante budget-neutral incentive progra...
• Hiding in the Herd: The Product Recall Clustering Phenomenon AI翻译

  摘要：Problem definition: Product recalls have serious consequences for firms and consumers. Little is known, however, about how firms manage the timing of recalls and how this timing influences the financial consequences of recalls. In this study, we provide evidence for a previously unknown phenomenon: recall clustering, a collection of recalls within close temporal proximity in which a leading recall (the first recall in a cluster) excites following recalls (subsequent recalls in a cluster). We a...
