  摘要：We develop a multistakeholder, multicriteria decision-making framework for Eurocontrol, the European air traffic management organization, for evaluating and selecting operational improvements to the air traffic management system. The selected set of improvements will form the master plan of the Single European Sky initiative for harmonizing air traffic, in an effort to cope with the forecasted increase in air traffic, while maintaining safety, protecting the environment, and improving predicta...
• Inventory models for substitutable products: Optimal policies and heuristics AI翻译

  摘要：In this paper, we examine the nature of optimal inventory policies in a system where a retailer manages substitutable products. We first consider a system with two products 1 and 2 whose total demand is D and individual demands are negatively correlated. A fixed proportion of the unsatisfied customers for an item will purchase the other item if it is available in inventory. For the single-period case, we show that the optimal inventory levels of the two items can be computed easily and follow ...
• Confidentiality and information sharing in supply chain coordination AI翻译

  摘要：We consider information sharing in a decentralized supply chain where one manufacturer supplies to multiple retailers competing in price. Each retailer has some private information about the uncertain demand function which he may choose to disclose to the manufacturer. The manufacturer then sets a wholesale price based on the information received. The information exchange is said to be confidential if the manufacturer keeps the received information to herself, or nonconfidential if she disclos...
• How near-misses influence decision making under risk: A missed opportunity for learning AI翻译
  作者：Dillon, Robin L.; Tinsley, Catherine H.

  摘要：Although organizations appear to learn from obvious failures, we argue that it is harder for them to learn from near-misses-events in which chance played a role in averting failure. In this paper, we formalize the concept of near-misses and hypothesize that organizations and managers fail to learn from near-misses because they evaluate such events as successes and thus feel safer about the situation. We distinguish perceived (felt) risk from calculated statistical risk and propose that lower l...
• A bargaining framework in supply chains: The assembly problem AI翻译
  作者：Nagarajan, Mahesh; Bassok, Yehuda
  作者单位：University of British Columbia; University of Southern California
  摘要：We examine a decentralized supply chain in which a single assembler buys complementary components from n suppliers and assembles the final product in anticipation of demand. Players take actions in the following sequence. First (stage 1), the suppliers form coalitions among themselves. Second (stage 2), the coalitions compete for a position in the negotiation sequence. Finally (stage 3), the coalitions negotiate with the assembler on allocations of the supply chain's profit. We model the multi...
• Fluid models for overloaded multiclass many-server queueing systems with first-come, first-served routing AI翻译

  摘要：Motivated by models of tenant assignment in public housing, we study approximating deterministic fluid models for overloaded queueing systems having multiple customer classes (classes of tenants) and multiple service pools (housing authorities), each with many servers (housing units). Customer abandonment acts to keep the system stable, yielding a proper steady-state description. Motivated by fairness considerations, we assume that customers are selected for service by newly available servers ...
• Managing the inventory of an item with a replacement warranty AI翻译

  摘要：In this paper, we study a firm that faces demand from two sources: demand for new items and demand to replace failed items under warranty. We model this setting as a multiperiod single-product inventory problem where the demands for new items in different periods are independent and the demands for replacing failed items depend on the number and ages of the items under warranty. We consider backlogging and emergency supply cases, and study both discounted cost and average cost criteria. We pro...
