摘要:Outsourcing of equipment repair and restoration is commonly practiced by firms in many industries. The operational performance of equipment is determined by joint decisions of the firm (client) and the service provider (vendor). Although some decisions are verifiable and thus directly contractible, many decisions are not. The result is a double-sided moral hazard environment in which each party has incentives to free ride on the other's effort. A performance-based contract allows the client to...

摘要:Subjective expected utility is the most widely used model to represent preferences under uncertainty (when objective probabilities of events may not be known). This paper presents a new behavioral characterization (preference axiomatization) of subjective expected utility. The latter is derived from a behavioral assumption of cardinal independence, also known as standard sequence invariance. This axiom requires that a standard sequence of outcomes (equally spaced in terms of utility) is indepe...

摘要:In this paper we present a unit commitment model for studying the impact of large-scale wind integration in power systems with transmission constraints and system component failures. The model is formulated as a two-stage stochastic program with uncertain wind production in various locations of the network as well as generator and transmission line failures. We present a scenario selection algorithm for selecting and weighing wind power production scenarios and composite element failures, and ...

摘要:We consider the feasibility problem OPP (orthogonal packing problem) in higher-dimensional orthogonal packing: given a set of d-dimensional (d >= 2) rectangular items, decide whether all of them can be orthogonally packed in the given rectangular container without rotation. The one-dimensional (1D) bar LP relaxation of OPP reduces the latter to a 1D cutting-stock problem where the packing of each stock bar represents a possible 1D stitch through an OPP layout. The dual multipliers of the LP pr...

摘要:We introduce a simple elicitation process where subject-matter experts provide only ordinal judgments of the attractiveness of potential targets, and the adversary utility of each target is assumed to involve multiple attributes. Probability distributions over the various attribute weights are then mathematically derived (using either probabilistic inversion or Bayesian density estimation). This elicitation process reduces the burden of time-consuming orientation and training in traditional me...

摘要:We study the performance of two popular and widely used heuristics for revenue management known as the booking limit and bid price controls. In contrast to a recent result in the literature where frequent re-solvings of a certain heuristic are shown to significantly reduce revenue loss, we show that the asymptotic revenue loss of either booking limit or bid price control cannot be reduced regardless of the choice of re-solving times and the frequency of re-solving. Moreover, we also show that ...

摘要:Connectivity requirements are a common component of forest planning models, with important examples arising in wildlife habitat protection. In harvest scheduling models, one way of addressing preservation concerns consists of requiring that large contiguous patches of mature forest are maintained. In the context of nature reserve design, it is common practice to select a connected region of forest, as a reserve, in such a way as to maximize the number of species and habitats protected. Althoug...

摘要:Nonstationary infinite-horizon Markov decision processes (MDPs) generalize the most well-studied class of sequential decision models in operations research, namely, that of stationary MDPs, by relaxing the restrictive assumption that problem data do not change over time. Linear programming (LP) has been very successful in obtaining structural insights and devising solution methods for stationary MDPs. However, an LP approach for nonstationary MDPs is currently missing. This is because the LP f...

摘要:This paper studies a repeated game between a manufacturer and two competing suppliers with imperfect monitoring. We present a principal-agent model for managing long-term supplier relationships using a unique form of measurement and incentive scheme. We measure a supplier's overall performance with a rating equivalent to its continuation Utility (the expected total discounted utility of its future payoffs), and incentivize supplier effort with larger allocations of future business. We obtain t...

摘要:We consider a service provider in a market with two segments. Members of the first request a reservation ahead of service and will not patronize the firm Without one. Members of the second walk in and demand service immediately. These customers have a fixed cost of reaching the firm and may behave strategically. In equilibrium, they randomize between walking in and staying home. The service provider must decide how much of a limited capacity to make available to advance customers. When the adv...
