一类过程需求存贮系统的策略研究及其费用弹性分析

本文首先讨论了需求到达为复合泊松随机过程的库存管理问题,给出了在单位时间内期望总成本费用最小的条件下的确定性的最优订货策略(Q,T).然后分析了在订购量和订购周期为随机变量,其联合分布已知的条件下,基于随机局部弹性理论,分析了总费用关于订购量和订购周期的局部弹性的联合分布,为订购策略的制定提供了合理的依据.

THE STUDY OF OPTIMAL POLICY ON A STOCHASTIC INVENTORY SYSTEM WITH COMPOUND POISSON DEMAND PROCESS

In this paper,We obtain the optimal ording policy(Q,T) of a stochastics inventory system with compound poisson demand process by minimzing the expected cost perunit time.Then we analyse the stochastic partial elasticity of the exepected total cost per unit time to the random ording quantity and random ording period,and have the joint distribution density of the stochastic partial elasticity of the exepected total cost per unit time to the random ording quantity and random ording period,by assuming that the joint distribution density of the random ording quantity and random ording period are known.Which provides a reasonable basis for the formilation of ording strategy.
