• Long-distance access network design AI翻译

  摘要：Long-distance telephone companies in the United States pay access fees to local telephone companies to transport calls that originate and terminate on their networks. These charges form the largest portion of the cost of providing long-distance service. Recent changes in the structure of access rates, which were mandated by the Federal Communications Commission (FCC), have created opportunities for long-distance companies to better manage access costs. In this paper, we develop an optimization...
• Modeling the impact of merging capacity in production-inventory systems AI翻译

  摘要：W e model two separate, decentralized systems, each consisting of a warehouse and a production capacity. The demand processes experienced by the systems have different variabilities. The two decentralized systems consider an agreement to pool their production capacities. We examine the impact of the pooling of capacity on inventory costs under two operating rules: (i) the orders from the two warehouses are treated in a first-come-first-served manner, and (ii) the orders from the lower-variabil...
• Metaheuristics with local search techniques for retail shelf-space optimization AI翻译

  摘要：Efficient shelf-space allocation can provide retailers with a competitive edge. While there has been little study on this subject, there is great interest in improving product allocation in the retail industry. This paper examines a practicable linear allocation model for optimizing shelf-space allocation. It extends the model to address other requirements such as product groupings and nonlinear profit functions. Besides providing a network flow solution, we put forward a strategy that combine...
• Organizational behavior, strategy, performance, and design in Management Science AI翻译
  作者：Boudreau, JW
  作者单位：University of Southern California
  摘要：This article provides a personal perspective on the themes and topics that have emerged in research published by the department of organizational behavior, in the first 50 years of Management Science. A review of articles accepted by the department suggests several themes that reflect broad objectives, such as improving management science models, or distinguishing points of view or assumptions, such as treating organizations as decision-making entities. The research is summarized through topic...
• Demand allocation in multiple-product, multiple-facility, make-to-stock systems AI翻译

  摘要：We consider the problem of allocating demand arising from multiple products to multiple production facilities with finite capacity and load-dependent lead times. Production facilities can choose to manufacture items either to stock or to order. Products vary in their demand rates, holding and backordering costs, and service-level requirements. We develop models and solution procedures to determine the optimal allocation of demand to facilities and the optimal inventory level for products at ea...
• Selectionism and learning in projects with complexity and unforeseeable uncertainty AI翻译
  作者：Sommer, SC; Loch, CH
  作者单位：Purdue University System; Purdue University; INSEAD Business School
  摘要：Companies innovating in dynamic environments face the combined challenge of unforeseeable uncertainty (the inability to recognize the relevant influence variables and their functional relationships; thus, events and actions cannot be planned ahead of time) and high complexity (large number of variables and interactions; this leads to difficulty in assessing optimal actions beforehand). There are two fundamental strategies to manage innovation with unforeseeable uncertainty and complexity: tria...
• Eliminating public knowledge biases in information-aggregation mechanisms AI翻译
  作者：Chen, KY; Fine, LR; Huberman, BA
  作者单位：Hewlett-Packard
  摘要：We present a novel methodology for identifying public knowledge and eliminating the biases it creates when aggregating information in small group settings. A two-stage mechanism consisting of an information market and a coordination game is used to reveal and adjust for individuals' public information. A nonlinear aggregation of their decisions then allows for the calculation of the probability of the future outcome of an uncertain event, which can then be compared to both the objective probab...
• A likelihood approach to estimating market equilibrium models AI翻译
  作者：Draganska, M; Jain, D
  作者单位：Stanford University; Northwestern University
  摘要：This paper develops a new likelihood-based method for the simultaneous estimation of structural demand-and-supply models for markets with differentiated products. We specify an individual-level discrete-choice model of demand and derive the supply side assuming manufacturers compete in prices. The proposed estimation method considers price endogeneity through simultaneous estimation of demand and supply, allows for consumer heterogeneity; and incorporates a pricing rule consistent with economi...
• Innovation and attention to detail in the quality improvement paradigm AI翻译
  作者：Naveh, E; Erez, M
  作者单位：Technion Israel Institute of Technology
  摘要：This study asserted that quality improvement (QI) requires the coexistence of two cultural values of innovation and attention to detail and proposed that their coexistence depends on the implementation of multiple QI practices. A longitudinal QI intervention, with five phases, consisting of multiple QI practices-ISO 9000, QI teams, quality goals, and coaching and communication by top management-was implemented. Participants were 425 employees working in 18 departments of four manufacturing pla...
• A comparison of VaR and CVaR constraints on portfolio selection with the mean-variance model AI翻译
  作者：Alexander, GJ; Baptista, AM
  作者单位：University of Minnesota System; University of Minnesota Twin Cities; George Washington University
  摘要：In this paper, we analyze the portfolio selection implications arising from imposing a value-at-risk (VaR) constraint on the mean-variance model, and compare them with those arising from the imposition of a conditional value-at-risk (CVaR) constraint. We show that for a given confidence level, a CVaR constraint is tighter than a VaR constraint if the CVaR and VaR bounds coincide. Consequently, a CVaR constraint is more effective than a VaR constraint as a tool to control slightly risk-averse a...
