生鲜食品的二级补货系统优化研究

针对连锁超市的配送网络。建立一个两级的库存系统模型，其中包括一个中心仓库和若干门店，每个门店面对的是随机的相互独立的需求，该需求服从正态分布。该库存系统是采用基于连续检测的再订货点方法管理。本文针对超市的生鲜食品补货的特征，增加对于过剩成本的考虑，采用分散库存控制权的方法，按照从门店到配送中心的思路。优化总库存成本，从而得出最佳的订购批量，同时也得出最佳的产品供给水平、再订货点等。

Optimization of Multiple-Echelon Control of Fresh Food

The distribution network is a Multi-Echelon inventory system,in which a distribution center and a number of retailers are included.The retailers face independent stochastic demand processes,and it can be expressed as normal distribution.The system is controlled by continuous review installation stock(R,Q) policies.This paper focuses on replenishment of fresh food.By decentralizing the inventory control,the total inventory cost(including overstock cost) can be optimized.At last,the best batch quantity,fill rate of a given product,reorder point and so on are all gained.
