带有可变备运期和有限服务率的经济批量模型

Economic Lot-Size Model with Variable Lead Time and Finite Service Rate

本文将备运期 (Leadtime)作为决策变量 ,在指数备运时间———费用函数的假定下 ,建立了服务率为有限的库存系统的最优经济批量模型 ,提供了寻求最佳备运期、最优订货周期及最优订货批量的简单方法 ,并给出了参数的灵敏度分析和应用实例 .

In this paper, Lead time is considered as decision variable. An optimal economic lot size model is developed for inventory system with finite service rate, under the assumption of exponential lead time cost function. A simple method is presented for determining the optimal lead time, the optimal order cycle and the optimal order lot size. Sensitivity analyses of parameters and applied examples are also shown.
