连续生产模式下的不常用备件联合采购优化分析

针对连续性生产企业不常用备件管理缺货费用难以确定的实际情况,讨论了服务水平约束的基于随机连续盘点策略的联合补充(s,C,S)随机库存问题,经与单独补充策略相比,发现其经济效益明显。同时对影响备件联合采购费用节约的因素进行敏感性分析,指出了进行此类备件库存优化的方向。

Coordinated Replenishment Problem of Rarely Used Spare Parts Based on Continue Production

In most circumstances,the stock-out cost of spare parts can’t be confirmed exactly because of the spe-cial characters of continuous production.Service level constrained(s,c,S)inventory model with continuous re-view policy for coordinated replenishment is established.Comparing with(s,S)policy,its advantage is tested through practical case.At the same time,sensitivity analysis for the factors to the cost saving of coordinated re-plenishment is accomplished and corresponding methods for inventory optimality are put forward for this sort of spare part.
