大型企业库存管理中的数学模型——转库流向优化及时间推荐

在供应—生产—销售的供销环节中 ,大型企业的出厂决策问题是非常重要和难解决的。本文以某钢铁厂出厂决策支持系统为背景 ,对其中业务管理中的库存管理建立起数学模型体系。分析了模型的特点 ,由于 0— 1归划为 NP—难问题 ( NP—完全问题 )及一些问题属于大规模资源优化问题 ,当问题规模增大时求解变得极其困难。针对这些问题的特点介绍了求解模型的算法 :现有程序包、启发式算法和线性规划与启发混合的算法。这些算法在应用中取得了较好的效果。

The Mathematic Model in the Large Enterprise Stock Manage-The optimize direction for change storeroom and commend the time

In the supply and marketing's tache of provide-produce-sell, the leave factory decision's problem in large Enterprise is very importance and very scabrous problem. In this paper,we strike up the mathematic model for storage manage in the steel plant with the leave factory decision sustain system as the background,analysis the specialty of the model due to the 0-1 program is the NP-hard problem(NP-complete problem)and sometime these problems belong to the large size resource optimize question,to try result become. The very difficulty when the problem's pattern is large.We introduce.The arithmetic of solving the model:in existence procedure,heuristic.Arithmetic and mixed arithmetic of mix linear program with heuristic,these arithmetic have better effect in the applications.
