  摘要：In the last two decades, terrorism has become a major issue around the world. We analyze a continuous conflict between a terrorist (Terrorist) and a passive defender (Defender). Defender is passive because her actions can influence only the costs (damages) when Terrorist attacks. We focus on high-trajectory fire attacks and passive responses to them in the conflict between Israel and the various terrorist groups in the Gaza Strip in accordance with scientific principles. We first consider thre...
• The Influence of Intellectual Property Rights on Poaching in Manufacturing Outsourcing AI翻译

  摘要：Manufacturers are often placing their intellectual property (IP) at risk by outsourcing to suppliers in countries with weak IP rights. Thus, understanding how to safeguard their IP from poaching, which is a supplier's unauthorized use of a buyer's proprietary information, is of critical practical importance for manufacturers that outsource to suppliers in countries with weak IP rights. To investigate this phenomenon, we use dyadic data from globally dispersed manufacturer-supplier relationship...
• Effects of Consumer-to-Consumer Product Sharing on Distribution Channel AI翻译

  摘要：In recent years, mobile communication technologies and online sharing platforms have made collaborative consumption among consumers a major trend in the economy. Consumers buy many products but end up not fully utilizing them. A product owner's self-use values can differ over time, and in a period of low self-use value, the owner may rent out her product in a product-sharing market. This study develops an analytical framework to study how consumer-to-consumer product sharing affects the distri...
• Horizontal Subcontracting From Competitors: When and What? AI翻译

  摘要：We investigate horizontal subcontracting between two firms that compete in selling to uncertain markets. Each firm manages resources to make a key component indispensable for final assembly by both firms. A horizontal subcontract stipulates that one of them prepares key component or even produces final product for the other. The subcontract can be signed before or after resource preparation, which we refer to as forward and spot subcontracting, respectively. With the presence of demand uncerta...

  摘要：Breast cancer, the leading cause of cancer death for women, can be detected at earlier stages through mammography screening. Therefore, most developed countries implemented population-based mammography screening programs. However, cost of mammography and limited resources in terms of number of trained personnel and diagnostic machines prevent mammography screening to be adopted by many other countries. In fact, even in resource-rich countries, there is a growing concern about cost of mammograp...
• Coordinated Scheduling for a Multi-server Network in Outpatient Pre-operative Care AI翻译

  摘要：Many parts of the healthcare system remain fragmented and outpatient surgical care is no exception. In this study, we develop a coordinated pre-operative scheduling approach between Anesthesiology and Internal Medicine to optimize patients' medical conditions prior to surgery. Coordinating these two services has conceptual appeal because any health issues discovered by the anesthesiologist can often be addressed by a general internist. We design a patient-centered approach that allows the pati...
• RFID Tag Performance: Linking the Laboratory to the Field through Unsupervised Learning AI翻译

  摘要：Despite the promise that the technology offers, RFID adoption continues to lag behind initial projections. Industry studies intimate that, in part, this lag is attributable to the RFID performance gap - the difference between desired RFID tag read-rates and those experienced in the field. To explore this phenomena, we employ a mixed research methodology involving intensive case studies of three major retailers as well as large-scale laboratory and field data collection and analysis. Our case s...
• Impact of Behavioral Factors on Performance of Multi-Server Queueing Systems AI翻译
  作者：Do, Hung T.; Shunko, Masha; Lucas, Marilyn T.; Novak, David C.
  作者单位：University of Vermont; University of Washington; University of Washington Seattle
  摘要：Recent studies have shown that the processing speed of employees in service-based queueing systems is impacted by various behavioral factors. However, there is limited analytical work to investigate how these behavioral factors affect the overall performance of different queueing system designs. In this study, we focus on the response of human servers to the design and congestion level of the queueing system in which they operate. Specifically, we incorporate two behavioral factors into multi-...
• Task Variety in Professional Service Work: When It Helps and When It Hurts AI翻译
  作者：Avgerinos, Emmanouil; Gokpinar, Bilal
  作者单位：IE University; University of London; University College London
  摘要：In a wide range of professional service firms, individuals perform a variety of tasks which are highly cognitive and knowledge intensive yet repetitive in nature, providing significant opportunities for learning. In addition, individuals in such environments tend to enjoy considerable discretion in managing when and how they perform their tasks. In light of these observations, we investigate task allocation and timing strategies that may enhance or inhibit learning and productivity for profess...
• Inventory Allocation in the Presence of Service-Level Agreements AI翻译

  摘要：Retailers often use service-level agreements (SLAs) to evaluate their supplier's performance. Based on an examination of 70 SLAs from practice, we conclude that in terms of evaluating fill rate, these SLAs vary in at least three key dimensions: (i) Supplier performance can be evaluated for each demand request or over some longer horizon, (ii) the acceptable fill rate can be 100% or something less than 100%, and (iii) the non-compliance charge can be a flat fee, a per-unit-short fee, or both. F...
