摘要：A fast and easily implementable approximation algorithm for the problem of finding a minimum makespan in a job shop is presented. The algorithm is based on a taboo search technique with a specific neighborhood definition which employs a critical path and blocks of operations notions. Computational experiments (up to 2,000 operations) show that the algorithm not only finds shorter makespans than the best approximation approaches but also runs in shorter time. It solves the well-known 10 x 10 ha...

摘要：We consider several coordination games with multiple equilibria each of which is a different division of a fixed pie. Laboratory experiments are conducted to address whether ''task complexity'' affects the selection of equilibrium by subjects. Three measures of task complexity-cardinality of choice space, level of iterative knowledge of rationality, and level of iterative knowledge of strategy-are manipulated and tested. Results suggest the three measures can predict choice behavior. Since str...

摘要：In this paper we propose a standard measure of risk that is based on the converted expected utility of normalized lotteries with zero-expected values. This measure of risk has many desirable properties that characterize the notion of risk. It is very general and includes many previously proposed measures of risk as special cases. Moreover, our standard measure of risk provides a preference-based and unified method for risk studies. Since the standard measure of risk is compatible with the meas...

摘要：This paper presents a maximum entropy framework for the aggregation of expert opinions where the expert opinions concern the prediction of the outcome of an uncertain event. The event to be predicted and individual predictions rendered are assumed to be discrete random variables. A measure of expert competence is defined using a distance metric between the actual outcome of the event and each expert's predicted outcome. Following Levy and Delic (1994), we use Shannon's information measure (Sha...

摘要：We consider multimachine scheduling problems with earliness and tardiness costs. We first analyze problems in which the cost of a job is given by a general nondecreasing, convex function F of the absolute deviation of its completion time from a (common) unrestrictive due-date, and the objective is to minimize the sum of the costs incurred for all N jobs. (A special case to which considerable attention is given is the completion time variance problem.) We derive an easily computable lower bound...

摘要：The objective of the present study was to develop a comprehensive empirically-based model of the communication interface between R&D and marketing. Following Moenaert and Souder (1990), a causal model of the antecedents of information utility at the R&D/marketing-interface was postulated. A non-experimental critical incident method was used to test the model. The field survey involved 386 team members of 80 new product innovation teams in 40 companies. Path analysis was used to test the causal...

摘要：Because of network externalities, the success of a software product may depend in part on stalled base and its conformance to industry standards. This research builds a hedonic model to determine the effects of network externalities, standards, intrinsic features and a time trend on microcomputer spreadsheet software prices. When data for a sample of products during the 1987-1992 time period were analyzed using this model, four main results emerged: 1) Network externalities, as measured by the...

摘要：In this paper we discuss stochastic Economic Lot Scheduling Problems (ELSP), i.e., settings where several items need to be produced in a common facility with limited capacity, under significant uncertainty regarding demands, production times, setup times, or combinations thereof. We propose a class of production/inventory strategies for stochastic ELSPs and describe how a strategy which minimizes holding, backlogging, and setup costs within this class can be effectively determined and evaluate...

摘要：Data truncation is a commonly accepted method of dealing with initialization bias in discrete-event simulation. An algorithm for determining the appropriate initial-data truncation point for univariate output is proposed. The technique entails averaging across independent replications and estimating a steady-state output model in a state-space framework. A Bayesian technique called Multiple Model Adaptive Estimation (MMAE) is applied to compute a time varying estimate of the output's steady-st...

摘要：This paper introduces a Bayesian decision theoretic model of optimal production in the presence of learning-curve uncertainty. The well-known learning-curve model is extended to allow for random variation in the learning process with uncertainty regarding some parameter of the variation. A production run generates excess value (above its current revenue) for a Bayesian manager in two ways: it pushes the firm further along the learning curve, increasing the likelihood of lower costs for future ...
