基于混合需求的二级库存系统协同订货模型
Collaborative ordering models of two-echelon inventory system based on hybrid demand
摘要
Abstract
In the general two-echelon inventory models, there exists a common assumption:the demand of every echelon is independent. But in fact, only the demand of the downstream node is independent, and the upstream node is correlated with the independent demand. Therefore, the collaborative ordering models of two-echelon inventory system based on hybrid demand are constructed. The different downstream nodes’ordering can be transformed into a virtual node’s ordering. The upstream node takes a collaborative ordering. Thus, through constant adjustment of the downstream nodes’orders, it can get the optimal strategy to make system inventory cost minimum. Then the genetic algorithms of these models are given. The simulation shows that they are good ways to get the satisfied order policy.关键词
