摘要：Many primary care offices and other medical practices regularly experience long backlogs for appointments. These backlogs are exacerbated by a significant level of last-minute cancellations or no-shows, which have the effect of wasting capacity. In this paper, we conceptualize such an appointment system as a single-server queueing system in which customers who are about to enter service have a state-dependent probability of not being served and may rejoin the queue. We derive stationary distri...

摘要：We study how innovators can optimally design licensing contracts when there is incomplete information on the licensee's valuation of the innovation, and limited control over the licensee's development efforts. A licensing contract typically contains an up-front payment, milestone payments at successful completion of a project phase, and royalties on sales. We use principal-agent models to formulate the licensor's contracting problem, and we find that under adverse selection, the optimal contra...

摘要：Recent efforts to develop a universal view of complex networks have created both excitement and confusion about the way in which knowledge of network structure can be used to understand, control, or design system behavior. This paper offers perspective on the emerging field of network science in three ways. First, it briefly summarizes the origins, methodological approaches, and most celebrated contributions within this increasingly popular. field. Second, it contrasts the predominant perspect...

摘要：The defined-benefit pension system poses substantial, long-term risks for the U.S. economy. We describe a flexible asset-liability management (ALM) system for pension planning. The primary goals are to improve the performance and survivability of the pension trust. We first employ a stochastic program for enhancing investment strategies in light of company and other goals and pension risk constraints. The results are linked with a policy simulator for further analysis. We illustrate the concep...

摘要：This paper reports on an application of network-flow integer programming to a vacation timeshare exchange problem. A typical timeshare owner has purchased yearly access to a specific week at a specific resort. The resulting lack of vacation variety is mitigated by systems that allow owners to exchange owned weeks for different weeks at different resorts according to their preferences, the assessed value of what they are exchanging, their contractual priority, and resort availability. The times...

摘要：we show the optimality of state-dependent echelon base-stock policies in uncapacitated serial inventory systems with Markov-modulated demand and Markov-modulated stochastic lead times in the absence of order crossing. Our results cover finite-time horizon problems as well as infinite-time horizon formulations, with either a discounted or an average cost criterion. We employ a novel approach, based on a decomposition of the problem into a series of single-unit single-customer problems that are ...

摘要：To optimize revenue, service firms must integrate within their pricing policies the rational reaction of customers to their price schedules. In the airline or telecommunication industry, this process is all the more complex due to interactions resulting from the structure of the supply network. In this paper, we consider a streamlined version of this situation where a firm's decision variables involve both prices and investments. We model this situation as a joint design and pricing problem th...

摘要：This paper presents a large-scale computationally intensive model for understanding the dynamic strategic evolution of electricity-generating asset portfolios in response to various market interventions, and the consequent longer-term effects of such changes on market structure and prices. We formulate a multistage model involving a Cournot representation of the wholesale electricity market, the performance of which then determines plant trading between players and the coevolution of market st...

摘要：Local distribution companies (LDCs) play the role of purchasing and delivering natural gas to their consumers, and state regulators oversee the pricing of natural gas to consumers. The common method of regulation, based on the cost of service, provides arguably little incentive for the LDC to optimally manage their procurement activities. In the light of recent deregulation and other changes, benchmarking-based regulatory schemes are being increasingly perceived as the right direction to pursu...

摘要：Information measures arise in many disciplines, including forecasting (where scoring rules are used to provide incentives for probability estimation), signal processing (where information gain is measured in physical units of relative entropy), decision analysis (where new information can lead to improved decisions), and finance (where investors optimize portfolios based on their private information and risk preferences). In this paper, we generalize the two most commonly used parametric famil...
