多级库存系统中安全库存与配送结构的关系分析
On the Connection between Optimal Stock Level and Distribution Structure in Multi-Echelon Storage System
-
摘要:对于不分层次的单级库存系统来说,安全库存总量与分散程度具有平方根关系。对于多级库存系统,通过理论分析与数值计算相结合的方法,给出了安全库存与配送结构(层次数与分叉度)之间的联系,其结果对配送结构设计具有很大的参考价值。Abstract:In a single-echelon system, the optimal stock level has a square root rule-of-thumb with respect to the furcation degree. For a multi-echelon storage system, the connection between its optimal stock level and distribution structure (echelon number and furcation degree) is obtained by combination of theoretical analysis and numerical calculation, supplying a significant reference for the design of distribution structure.
