摘要:This article presents a risk-sensitive pricing model to maximize sales revenue of perishable commodities with fixed capacity and finite sales horizon. The model assumes a pair of predetermined prices and the Poisson demand process whose intensity is a decreasing function of price. When optimizing the expected revenue, management takes business risk into account by adding a penalty (or premium) to the objective function. We solve the continuous-time model with the exact solution in closed form....

摘要:Many firms in the oil and gas business have long used decision analysis techniques to evaluate exploration and development opportunities and have looked at recent development in option pricing theory as potentially offering improvements over the decision analysis approach. Unfortunately, it is difficult to discern the benefits of the options approach from the literature on the topic: Most of the published examples greatly oversimplify the kinds of projects encountered in practice, and comparis...

摘要:We provide a decision analysis perspective on the decision making process leading to the merger of The Institute of Management Sciences (TIMS) and the Operations Research Society of America (ORSA) to form the Institute for Operations Research and the Management Sciences (INFORMS). Throughout the merger negotiation era from 1989 until the merger in 1995, discussion regarding a possible merger was framed in an objectives-oriented manner characteristic of decision analysis methods. In addition, a...

摘要:The recent HIV incidence rate (or hazard rate for infection) is an important quantity for use in monitoring the HIV/AIDS epidemic, evaluating HIV prevention programs, and allocating HIV prevention resources. Direct measurement of HIV incidence is difficult and time consuming, while estimating HIV incidence via backcalculation (deconvolution) using AIDS incidence data. and the (presumed known) HIV incubation time distribution yields little information about recent infection. We propose a method...

摘要:In stochastic dynamic programming (SDP) with continuous stare and decision variables, the future value function is computed at discrete points in the state space. Interpolation can be used to approximate the values of the future value function between these discrete points. However, for large dimensional problems the number of discrete points required to obtain a good approximation of the future value function can be prohibitively large. Statistical methods of experimental design and function ...

摘要:Part I of a two-part series, this paper recites a parable and formulates a stochastic optimization model that determines optimal link tolls on a road network whose users' value of time is a random variable. The parable, introducing the problem, demonstrates the importance of the variability of the value of time. The model, cast as a variational inequality, becomes a specialized form of a bicriterion user-equilibrium traffic assignment. Its solution is a set of efficient tolls for all links in ...

摘要:Material handling systems are almost always intertwined with the production system they serve, but problems at this interface are rarely considered together. This paper develops a model that explicitly considers the costs of material handling and inventory to simultaneously design a material handling system and set shop floor inventory policy. The research was inspired by material handling problems we observed at computer manufacturing companies such as Apple Computer and Hewlett Packard Compa...

摘要:We consider networks in which a cost is associated with each are or edge and a transition cost is associated with each node. This last cost is related to the presence of two technologies on the network and is incurred only when a flow enters and leaves the corresponding node on arcs of different types. The problem we consider consists in finding two node disjoint paths with minimum total cost. We show that it is strongly NP-complete. Then we propose two heuristics, study their worst case behav...

摘要:This article proposes large-scale convex optimization problems to be solved via saddle points of the standard Lagrangian. A recent approach for saddle point computation is specialized, by way of a specific perturbation technique and unique scaling method, to convex optimization problems with differentiable objective and constraint functions. In each iteration the update directions for primal and dual variables are determined by gradients of the Lagrangian. These gradients are evaluated at pert...

摘要:An oligopoly with spatially dispersed generators and consumers and with multi-period demand is modeled in this paper. The producers are assumed to behave in a Cournot manner with regulated transmission prices. A (generalized) Nash equilibrium is sought. The story of the game is as follows. Each generator lakes its rivals' output (generation, supply, and flows) and the prices for transmission services as fixed when it decides upon its output to maximize its profit; the transmission firm takes t...
