基于累积损伤过程的随机需求下订购时间间隔模型

Fixed order time interval model based on cumulative damage process

将累积损伤过程运用于固定订购时间间隔模型中,把订单的出现看成库存系统受到的冲击,把订单产生的随机需求量看成给库存系统的冲击带来的损伤,以求得最低期望单位时间成本为目标,建立C(T,K)成本模型,最后用一个算例展示了当成本最低时的最优订购时间间隔和初始库存水平。

Cumulative damage was used in a fixed order time interval model.The order was supposed to be the shock to the systems,and the random demand caused by each order was supposed to be the damage caused by the shock.The expected minimum unit time was found to set a model.A numerical example showed the optimal order time interval and the inventory level at minimum cost.
