具有随机需求过程和随机供货时间的库存模型

INVENTORY MODEL WITH STOCHASTIC DEMAND PROCESS AND STOCHASTIC REPLENISHMENT TIME

现代生产制造系统对库存理论及其数学模型提出了更高的要求 .从库存的角度而言 ,JIT和 MRP 代表了现代生产库存的两种重要理念 ,但也一直被认为有本质的区别 .结合现代生产及 JIT和 MRP 的特点 ,建立了一种具有随机需求过程和随机供货时间的库存模型 .

The modern production systems have called for a high level inventory theory and inventory model. From the viewpoint of inventory,JIT and MRPⅡ represent two important notions of the modern production inventory theory, and it has been considered that there is essential distinction between them. Combined with the characteristics of the modern production,and JIT and MRPⅡ,a new inventory model with stochastic demand process and stochastic replenishment time is given in this paper.
