• Improving the Accuracy of Project Schedules AI翻译

  摘要：How to avoid project failures driven by overoptimistic schedules? Managers often attempt to mitigate the duration underestimation and improve the accuracy of project schedules by providing their planners with excessively detailed project specifications. While this traditional approach may be intuitive, solely providing more detailed information has proven to have a limited effect on eliminating behavioral biases. We experimentally test the effectiveness of providing detailed specification and ...
• A Review of Flexible Processes and Operations AI翻译

  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...
• Impact of Penalty Cost on Customers' Booking Decisions AI翻译

  摘要：We study a novel newsvendor-type problem where the information on demand quantity is not exogenously given. The customer needs to make the booking decision based on her estimation on demand, which is affected by the value of shortage penalty cost. The problem is motivated by low-cost airline service practices where passengers need to book baggage allowance for their travel. The baggage overweight price affects the accuracy of passengers' baggage weight estimation and thus their booking quantit...
• A Survey of Recent Progress in the Asymptotic Analysis of Inventory Systems AI翻译
  作者：Goldberg, David A.; Reiman, Martin, I; Wang, Qiong

  摘要：It has long been recognized that many inventory models most relevant to practice are inherently high-dimensional, and hence generally believed to become computationally intractable as certain problem parameters grow large (suffering from the curse of dimensionality). In the last decade, asymptotic analysis has shown that in many interesting settings such problems can actually be well-approximated by much simpler optimization problems, leading to new algorithms and insights. In this survey, we ...
• An Investigation into Direct Selling: Information Flow and Supply Chain Structure AI翻译
  作者：Hao, Zhongyuan; Jiang, Li
  作者单位：Dongbei University of Finance & Economics; Hong Kong Polytechnic University
  摘要：Amid the rapid development of technology, an increasing number of suppliers sell directly as well as through the retail channel, competing with retailers in the market with uncertain demand. Each firm has exclusive access to a signal useful in updating market forecast. The quality of the signal received exclusively by a supplier is low when it adheres to the retail channel but improves after it engages in direct selling. Firms communicate signals along two directions. Competing suppliers or re...
• Payment for Results: Funding Non-Profit Operations AI翻译
  作者：Sharma, Neha; Devalkar, Sripad K.; Sohoni, Milind G.

  摘要：Payment for results (PfR) funding approach, where donors reimburse the non-profit organization (NPO) based on outcomes, is being increasingly adopted in the non-profit sector. However, there is also concern expressed by many voluntary organizations that such a funding approach puts an undue financial burden on small NPOs and could actually be detrimental to social welfare. In this study, we build a theoretical framework to analyze PfR funding mechanisms. We use a sequential game to model the i...
• A Review of Robust Operations Management under Model Uncertainty AI翻译
  作者：Lu, Mengshi; Shen, Zuo-Jun Max
  作者单位：Purdue University System; Purdue University; University of California System; University of California Berkeley; University of California System; University of California Berkeley
  摘要：Over the past two decades, there has been explosive growth in the application of robust optimization in operations management (robust OM), fueled by both significant advances in optimization theory and a volatile business environment that has led to rising concerns about model uncertainty. We review some common modeling frameworks in robust OM, including the representation of uncertainty and the decision-making criteria, and sources of model uncertainty that have arisen in the literature, such...
• When Does Dispute Resolution Substitute for a Reputation System? Empirical Evidence from a Service Procurement Platform AI翻译
  作者：Burtch, Gordon; Hong, Yili; Kumar, Senthil
  作者单位：University of Minnesota System; University of Minnesota Twin Cities; University of Houston System; University of Houston
  摘要：We consider the role of online dispute resolution (ex-post guarantees of supplier quality) when introduced in the presence of an online reputation system (an ex-ante informational mechanism), in the context of online service procurement platforms. We argue that dispute resolution will reduce buyers' reliance on reputation systems in their hiring decisions to varying extents, depending on the nature of the work required. We assess these predictions using proprietary data capturing projects, ser...
• Printing Spare Parts at Remote Locations: Fulfilling the Promise of Additive Manufacturing AI翻译
  作者：Westerweel, Bram; Basten, Rob; den Boer, Jelmar; van Houtum, Geert-Jan
  作者单位：Eindhoven University of Technology
  摘要：We investigate the benefits of on-site printing at remote geographic locations, where access to spare parts is intermittent and supplies are replenished at fixed intervals. Organizations typically have no solution to spare parts shortages other than expensive expediting orders, or waiting for a part to arrive with the next replenishment. We investigate whether on-site three-dimensional (3D) printing of spare parts can bring relief. Our work extends dual-sourcing literature with fixed order cyc...
• Analytics for Hospital Resource Planning-Two Case Studies AI翻译

  摘要：Using real data and process flows from two large hospitals (in Singapore and in Chengdu, China) as cases, we illustrate how to apply certain modeling and optimization techniques, along with simulation as a validation tool, to hospital resource planning problems. We demonstrate how these simple analytical tools can help achieve significant improvements in both patient service and resource utilization, and without the need to increase the overall level of existing capacities. Two resource planni...
