摘要:This paper offers an introductory view of the concept of habitual domains. It describes how they affect behavior, discusses their formation, dynamics, stability, and application, and points out how to expand and enrich them. Finally, this concept is related to the operations research profession to suggest how its habitual domains can be expanded and enriched to make OR workers more effective, both individually and collectively.

摘要:A new methodology provides military decision makers with information on the aggregate effectiveness of large-scale conventional (nonnuclear) and combined nuclear and conventional force structures against a wide range of targets. This methodology coupled a generic data base of representative targets, to which real-world targets can be mapped, with a nuclear force-exchange model that uses goal programming techniques to determine optimal allocations of weapons to targets. This methodology enabled...

摘要:This paper proposes a classification scheme for discrete manufacturing systems. It also includes a brief discussion of modeling, analysis, and optimization techniques that have been applied to manufacturing. This taxonomy is intended to be a first step in fitting existing environments to models. This will indicate directions for future manufacturing modeling and analysis,

摘要:In this paper we present two iterative methods for solving a model to evaluate busy probabilities for Emergency Medical Service (EMS) vehicles. The model considers location dependent service times and is an alternative to the mean service calibration method; a procedure, used with the Hypercube Model, to accommodate travel times and location-dependent service times. We use monotonicity arguments to prove that one iterative method always converges to a solution. A large computational experiment...

摘要:Frequency domain methodology has been applied to discrete-event simulations to identify terms in a polynomial model of the simulation output. In this paper, the problem of optimally selecting input frequencies is studied. A fast algorithm is presented that closely approximates the optimal solution. The results obtained from the algorithm are compared to known optimal solutions. Tables of input frequencies for various experiments are presented in an appendix.

摘要:The function of a digital telecommunications network is to transport demand of digital signals between pairs of locations. To achieve this economically, multiplex equipment packs lower rate digital signals into higher rate signals for routing over transmission facility links. Given a multiperiod demand forecast and demand routing plan, the multiplex bundling problem minimizes equipment and transmission costs by demultiplexing the higher rate signals into their lower rate components at various ...

摘要:We present a class of shake-and-bake algorithms for generating (asymptotically) uniform points on the boundary of full-dimensional bounded polyhedra. We also report results of simulations for some elementary test problems.

摘要:We extend the list of linear programming problems that are known to be solvable in strongly polynomial time to include a class of LPs which contains special cases of the generalized transshipment problem. The result is facilitated by exploiting some special properties associated with Leontief substitution systems and observing that a feasible solution to the system, Ax = b, x greater-than-or-equal-to 0, in which no variable appears in more than two equations, can be found in strongly polynomia...

摘要:This paper considers tradeoffs between cost and perturbations of the weights in a single facility, minisum location problem over a finite set of feasible points. Specifically, the paper characterizes a tradeoff curve of variability in the weights versus the degree of optimality of a solution. The general theoretical framework includes problems of location on a tree network and location using block norms; special results are given for these cases.

摘要:A hierarchical approach to control a manufacturing system, subject to multiple machine states modeled by a Markov process with weak and strong interactions, is suggested. The idea is to aggregate strongly interacting or high transition probability states within a group of states and consider only the transition between these groups for the analysis of the system in the long run. We show that such an aggregation results in a problem of reduced size, whose solution can be modified in a simple wa...
