  摘要：We analyze the problem faced by companies that rely on TL (Truckload) and LTL (Less than Truckload) carriers for the distribution of products across their supply chain. Our goal is to design simple inventory policies and transportation strategies to satisfy time-varying demands over a finite horizon, while minimizing systemwide cost by taking advantage of quantity discounts in the transportation cost structures. For this purpose, we study the cost effectiveness of restricting the inventory pol...

  摘要：A large midwestern hospital is expecting an increase in, surgical caseload: New operating, room (OR) capacity can be had by building new ORs or extending the working hours in the current ORs. The choice among these options is complicated by the fact that patients; surgeons and, surgical staff, and hospital administrators are all important stakeholders in: the health service operation, and each has different priorities. This. paper investigates the trade-offs among three performance criteria (w...
• Optimal dynamic auctions for revenue management AI翻译

  摘要：We analyze a dynamic auction, in which a seller, with C units to sell faces a sequence of buyers separated into T time periods. Each group of buyers has independent, private values for a single unit. Buyers compete directly against each other within a period, as in a traditional auction, and indirectly with buyers in other periods through the opportunity cost of capacity assessed by the seller. The number of buyers in each period, as well as the individual buyers' valuations, are random. The m...
• Coordinating mechanisms in care provider groups: Relational coordination as a mediator and input uncertainty as a moderator of performance effects AI翻译
  作者：Gittell, JH
  作者单位：Brandeis University
  摘要：This paper proposes a model of how coordinating mechanisms work, and tests it in the context of patient care. Consistent with organization design theory, the performance effects of boundary spanners and team meetings were mediated by relational coordination, a communication- and relationship-intensive form of coordination. Contrary to organization. design theory, however, the performance effects of routines were also mediated :by relational coordination. Rather than serving as a replacement fo...
• Return on assets loss from situational and contingency misfits AI翻译
  作者：Burton, RM; Lauridsen, J; Obel, B
  作者单位：Duke University; University of Southern Denmark; University of Southern Denmark
  摘要：We develop a rule-based contingency misfit model and related hypotheses to test empirically the Burton and Obel (1998) multicontingency model forstrategic organizational design: The model is a set of if-then misfit rules, in which misfits lead to a loss in performance; they are complements to the strategy and organizational contingency theory fit rules. Using data from 224 small- and medium-sized Danish firms, misfits are categorized, and; identified: Then, performance hypotheses, are develope...
