冲击型负荷下的生产存储模型研究

建立了考虑冲击需求、变化生产率的最优生产存储库存策略. 其特点是:把一个生产周 期分为多个生产阶段,各个生产阶段时间可以不同;在每个生产阶段中,允许生产率小于需求 率,允许提前生产;而且,最大生产率要小于最大需求率. 研究发现,为满足冲击需求,提前存储 较多而启动机器数量较少,或提前存储较少而启动机器数量较多,不一定能够取得最佳效益, 要根据存储费用和启动费用共同确定. 在有限生产率的条件下,得出一种寻求最优生产- 库存 策略,为此类库存系统的管理决策提供了理论依据.

Research of product inventory under impact load

A product inventory optimal policy under impact load is established in this paper. The properties of the policy are that every production period is partitioned into multiphase in which time duration is different , the produc2 tivity can be less than demand rate in every product phase(the maximum productivity is lower than the maximum de2 mand rate) , and preproduction are permitted. Given the bounded productivity , we obtain a product2inventory opti2 mal policy which supplies a theoretic base for management and decision2making of inventory system by using a one2 dimensional search method
