随机需求下两层供应链问题的模型探究

An inquiry of the model for the tow-echelon supply chain problem under stochastic demand

供应链管理问题是目前企业界和商业界关注的热点问题。供应链管理问题的实质是如何协调供应链中各成员企业的局部利益与供应链系统整体的关系,使供应链系统整体的总成本最低。在随机需求下,研究了单个供应商与多个零售商的随机供应链模型;并且在供应商和零售商不允许缺货和允许缺货情况下,给出了一个一般模型,分析并给出供应链合作的条件。

The problem of supply chain management is a hot problem that enterprise departments and commerce departments care about. The central point at issue about supply chain management is how to coordinate the partial and local interests of the member enterprise in the supply chain and the whole interests of the supply chain system, which aims to make the cost of tile supply chain system reach the lowest cost. A stochastic supply chain model having one supplier and multiple retailers was considered. A general model was given under the circumstances that the retailer allowed to be in short supply or not allowed to be in short supply. The conditions were given to supply chain cooperation.
