摘要：In this paper we develop a policy model for, pollution control investment and operational decisions in the copper industry. The system consists of (i)a nonlinear integer model to optimize smelter operations, including the investment decisions relating to smelting capacity and pollution control plants that complies with environmental regulations, and (ii) a network flow model to describe the economic behavior of the sulfuric acid, market, which considers the sulfuric acid produced at the pollut...

摘要：In an earlier study we examined the available evidence on the Edelman Prize finalist applications 1989-1998. This study concluded that 13 of the 42 private sector applications provide examples of strategic operations research (SOR) when SOR is defined as operations research that creates a sustain-able competitive. advantage. In a follow-up study we tested our classifications, gathering longitudinal information on the continued success, of the Edelman applications. We contacted people who were ...

摘要：As the 2000 election so vividly showed, it is Electoral College standings rather than national popular votes that determine who becomes President. But current pre-election polls focus almost exclusively on the popular vote. Here we present a method by which pollsters can achieve both point estimates and margins of error for a presidential candidate's electoral-vote total. We use data from both the 2000 and 1988 elections to illustrate the approach. Moreover, we indicate that the sample sizes n...

摘要：We examine the mechanism-design problem for a single buyer to procure purchase options for a homogeneous good when that buyer is required to satisfy an unknown future demand. Suppliers have two-dimensional types in the form of commitment costs and production costs. The efficient schedule of options depends on the distribution of demand. To implement an efficient outcome, we introduce a class of mechanisms which are essentially, pivotal mechanisms (Vickrey-Clarke-Groves) with respect to the exp...

摘要：American-Asian options are average-price options that allow early exercise. In this paper, we derive structural properties for the optimal exercise policy, which are then used to develop an efficient numerical algorithm for pricing such options. In particular, we show that the optimal policy is a threshold policy: The option should be exercised as soon as the average asset price reaches a characterized threshold, which can be written as a function of the asset price at that time. By exploiting...

摘要：All-optical networks with wavelength division multiplexing (WDM) capabilities are prime candidates for future wide-area backbone networks. The simplified processing and management of these very high bandwidth networks make them very attractive. A procedure for designing low cost WDM networks is the subject of this investigation. In the literature, this design problem has been referred to as the routing and wavelength assignment problem. Our proposed solution involves a three-step process that ...

摘要：This paper presents a modeling framework for analyzing competition between multiple firms that each possess a mixture of hydroelectric and thermal generation resources. Based upon the concept of a Cournot oligopoly with a competitive fringe, the model characterizes the Cournot equilibrium conditions of a multiperiod hydrothermal scheduling problem. Using data from the western United States electricity market, this framework is implemented as a mixed linear complementarity model. The results sh...

摘要：Responding to varying customer needs for product customization, quantities, or lead times requires increased manufacturing flexibility. In certain contexts, the reverse is true, i.e., customer requirements are somewhat flexible, providing additional options in production planning. This paper considers such an opportunity faced by a specialty steel manufacturer whose customers allow flexibility in product specifications. We develop and test a model and solution methodology to exploit this flexi...

摘要：Consider the following due-date scheduling problem in a multiclass, acyclic, single-station service system: Any class k job arriving at time t must be served by its due-date t+D-k. Equivalently, its delay tau(k) must not exceed a given delay or lead-time D-k. In a stochastic system, the constraint tau(k) less than or equal to D-k must be interpreted in a probabilistic sense. Regardless of the precise probabilistic formulation, however, the associated optimal control problem is intractable. wit...

摘要：In a batch-processing network, multiple jobs can be formed into a batch to be processed in a single service operation. The network is multiclass in that several job classes may be processed at a server. Jobs in different classes cannot be mixed into a single batch. A batch policy specifies which class of jobs is to be served next. Throughput of a batch-processing network depends on the batch policy used. When the maximum batch sizes are equal to one, the corresponding network is called a stand...
