This work is concerned primarily with presenting techniques for constructing bimatrix games with predetermined equilibrium points. Some partial results on Nash-solvability are also given. 相似文献

The 0-1 multiple-knapsack problem is an extension of the well-known 0-1 knapsack problem. It is a problem of assigning m objects, each having a value and a weight, to n knapsacks in such a way that the total weight in each knapsack is less than its capacity limit and the total value in the knapsacks is maximized. A branch-and-bound algorithm for solving the problem is developed and tested. Branching rules that avoid the search of redundant partial solutions are used in the algorithm. Various bounding techniques, including Lagrangean and surrogate relaxations, are investigated and compared. 相似文献

Recurrence relations for the product moments of order statistics from a doubly truncated exponential distribution are obtained. These relations allow us to evaluate the product moments for all sample sizes. 相似文献

In conclusion, let me raise the question of whether the Law Panel can impact these cycles or reverse these trends. If they are regarded as historical imperatives, the answer is clearly No. But we have been urged to be bold and to try to devise a new, simplified statute that will take us back to a better day. We are going to do that, without regard to the question whether Congress will accept the solution.
There probably has never been a better time for the Panel's report than the present; the window of opportunity is open. But what the Panel recommends is going to be awfully hard to sell, even in a window-of-opportunity year. If the predictions come true about the defense budget's going down to the level of the period when Eisenhower remained a Major for 14 years, maybe Congress will be receptive to anything that adds a little bit of value to the defense dollar. With this in mind, the Law Panel is likely to be very bold in its attempt to streamline the procurement system and reduce oversight. Hope springs eternal . . . . 相似文献

This article gives a full analysis of a component-replacement model in which preventive replacements are only possible at maintenance opportunities. These opportunities arise according to a Poisson process, independently of failures of the component. Conditions for the existence of a unique average optimal control limit policy are established and an equation characterizing the optimal policy and minimal average costs is derived. An important result is that the optimal policy can be described as a so-called one-opportunity-look-ahead policy. Such policies play an important role as heuristics in more general models. It is shown that there is a correspondence with the well-known age-replacement model, which can be considered as an extreme case of the model. Finally, some numerical results are given. 相似文献

Consider a renewal process whose interrenewal-time distribution is phase type with representation (α, T). We show that the (time-dependent) excess-life distribution is phase type with representation (α′, T), where α′ is an appropriately modified initial probability vector. Using this result, we derive the (time-dependent) distributions for the current life and the total life of the phase-type renewal process. They in turn enable us to obtain the equilibrium distributions for the three random variables. These results simplify the computation of the respective distribution functions and consequently enhance the potential use of renewal theory in stochastic modeling—particularly in inventory, queueing, and reliability applications. © 1992 John Wiley & Sons, Inc. 相似文献
