• Regret in the Newsvendor Model with Demand and Yield Randomness AI翻译
  作者：Chen, Zhi; Xie, Weijun

  摘要：We study the fundamental stochastic newsvendor model that considers both demand and yield randomness. It is usually difficult in practice to describe precisely the joint demand and yield distribution, although partial statistical information and empirical data about this ambiguous distribution are often accessible. We combat the issue of distributional ambiguity by taking a data-driven distributionally robust optimization approach to hedge against all distributions that are sufficiently close ...
• Who Takes Risks? A Framework on Organizational Risk-Taking During Sudden-Onset Disasters AI翻译

  摘要：Do humanitarian organizations exhibit similar risk-taking behavior? This study analyzed 60 interviews from 24 case studies on four types of organizations involved in disaster response: established, expanding, extending, and emergent. By elaborating on organizational attention theory, this study investigated how organizational tasks, structures, attention, and context combine to influence organizational risk-taking behavior by different organizational types during sudden-onset disasters. Counte...
• Seemingly-Beneficial Interventions AI翻译

  摘要：Organizations routinely introduce hitherto-unexplored interventions to improve their supply chains. Consider a principal (e.g., a firm) that implements a seemingly helpful intervention: For any fixed actions of the principal and the agents (e.g., consumers), the principal's payoff is higher in the presence of the intervention than in its absence. While one would expect such well-intentioned interventions to benefit the principal, several papers within the operations management (OM) literature ...
• Retailing with 3D Printing AI翻译

  摘要：Given the promise of three-dimensional (3D) printing, also known as additive manufacturing, some innovative consumer goods companies have started to experiment with such a technology for on-demand production. In this study, we consider two adoption cases of 3D printing in a dual-channel (i.e., online and in-store) retail setting, and evaluate its impact on a firm's product offering, pricing, and inventory decisions. Our analysis uncovers the following effects of 3D printing. First, 3D printing...
• A Review of Flexible Processes and Operations AI翻译
  作者：Wang, Shixin; Wang, Xuan; Zhang, Jiawei
  作者单位：New York University; Hong Kong University of Science & Technology
  摘要：One effective means to hedge against uncertainty and better match supply with demand in a swiftly changing environment is to adopt a flexible operations strategy that allows timely response to realized demand. The notion of flexible processes and operations has led to significant impact on the performance of many manufacturing and service applications. However, investing a fully flexible system is usually prohibitively expensive with overwhelming implementation complexity and overhead. As a re...
• Crossing Minimal Edge-Constrained Layout Planning using Benders Decomposition AI翻译
  作者：Sudermann-Merx, Nathan; Rebennack, Steffen; Timpe, Christian

  摘要：We present a new crossing number problem, which we refer to as the edge-constrained weighted two-layer crossing number problem (ECW2CN). The ECW2CN arises in layout planning of hose coupling stations at BASF, where the challenge is to find a crossing minimal assignment of tube-connected units to given positions on two opposing layers. This allows the use of robots in an effort to reduce the probability of operational disruptions and to increase human safety. Physical limitations imply maximal ...
• Building the Momentum: Information Disclosure and Herding in Online Crowdfunding AI翻译
  作者：Xiao, Shengsheng; Ho, Yi-Chun (Chad); Che, Hai
  作者单位：Shanghai University of Finance & Economics; George Washington University
  摘要：In online crowdfunding markets, backers face high uncertainty about the quality of a campaign. To mitigate such uncertainty, crowdfunding platforms often allow campaign creators to post communicative messages-that is, campaign updates and creator comments-to dynamically disclose further information about the campaigns. In addition, previous funding transactions of ongoing campaigns are made publicly available, giving rise to herding among backers. In this research, we aim to understand how com...
• Inter-Retailer Channel Competition: Empirical Analyses of Store Entry Effects on Online Purchases AI翻译
  作者：Tang, Qian; Lin, Mei; Kim, Youngsoo

  摘要：This study empirically examines the effect of offline store entry on a competing online retailer in the footwear industry and investigates how this effect depends on the relative product assortment and price between the offline store and the online retailer. Using transaction data from a large online footwear retailer and offline store entry data from 19 major shoe retail chains and 3 department store chains, we quantify the entry effect of offline stores. Categorizing offline stores by assort...
• Supplier Encroachment with a Dual-Purpose Retailer AI翻译
  作者：Wang, Ningning; Li, Zhuoxin
  作者单位：China University of Petroleum; Boston College
  摘要：The development of e-commerce has greatly facilitated the practice that suppliers encroach upon the retail realm of downstream retailers through direct channels (e.g., online stores). The literature in this area has investigated profit-maximizing firms, but the role of other organizational structures is not well understood. This study studies supplier encroachment in which the retailer is a dual-purpose corporation that pursues his own profit as well as consumer surplus. We find that the retai...
• Care-coordination: Gain-sharing Agreements in Bundled Payment Models AI翻译

  摘要：We study gain-sharing agreements in a target price-minimum quality payment system. Our work is inspired by the Centers for Medicare and Medicaid Services' (CMS) Comprehensive Care for Joint Replacement (CJR) bundled payment model. In our model, patients receive care from a hospital and a post-acute care provider. A third-party payer establishes target levels for total billing by the hospital and provider, and a target on the overall quality of care. The hospital and provider receive fee-for-se...
