摘要:

AbstractMost problems in management involve multiple goals and two approaches to solving managerial problems have been suggested:optimizingandsatisficing. The first covers methods of trade-offs, optimizing in tandem, conversion of goals into constraints and goal programming. The second mainly centres on norm setting and on interval programming. It is argued that cost-benefit analysis essentially belongs to the first group and that, contrary to some suggestions, the differences between the industrial and public sectors (as far as O.R. is concerned) are not related to differences between the optimizing and satisficing philosophies.

摘要:

AbstractThis paper reviews the philosophical questions of model validity and describes the need for practical tests of the adequacy and representativeness of computerized simulation models. The distinction between the concepts of the verification and the validation of such general models is made by means of a delineation of test procedures, primarily those of a statistical nature, which are applicable to the determination of a simulation model's adequacy.

摘要:

AbstractIt is demonstrated that mixed-integer programming can be applied successfully to the solution of certain practical site location problems. A mixed-integer model of a frequently occurring form of warehouse location problem is presented. Experience with models of this type is described with examples of computational performance. The flexibility of mixed-integer models and the approach to their use as aids to decision-making are discussed.

摘要:

AbstractIn this paper the effects of technical change on the optimal lives of assets are explored. The generality of the dynamic programming approach to the problem of optimal asset life determination is contrasted with the traditional and highly restrictive "equal life" solution. Some of the possible effects of different forms of technical change on costs are examined and numerical examples of these are solved by dynamic programming to illustrate the consequences for the optimal lives of assets. We hypothesize that the likely effect of technical progress is a lengthening of the optimal replacement cycle.

摘要:

AbstractThis study describes an analysis of seven distance functions with reference to their ability to estimate road distances between cities. The optimal parameters of each function are determined in relation to two samples of data, using two distinct goodness-of-fit criteria. A set of general statistical methods were chosen and applied to the comparison of the estimating power of the functions. Some properties of thelpdistance function are also given with reference to its use in facilities location models.

摘要:

AbstractAn exact expression for protection and potential lost sales is obtained for a reorder level system of inventory control in which the demand is normally distributed and the lead time gamma distributed. The accuracy of an approximate method is explored.
