基于两级供应链的退货政策研究

Returns Policy Research based on Two-level's Supply Chain

针对流行性商品需求不确定及生命周期短暂的特性,制造商对零售商采取全部退货政策。文章是在由制造商和零售商组成的两级供应链情况下,以双方及供应链整体利润为目标,就退货政策使用前后进行比较建立数学模型。最后,用数学软件对模型进行分析,结果表明,加入退货政策后,无论退货价格如何,供应链整体利润均增加,但只有退货价格在一定的范围内,才可以同时增加供应链双方的利润,达到供应链协调。

Aimed at characteristics of indefinite demand and the short-life cycle of the epidemic commodity,the manufacturer adopts complete returns policy to the retail.In the situation of two level＇s supplies chains composed by a manufacturer and a retail,this article takes bilateral and the supply chain overall profits as the goal establishing mathematical model,carrying on the comparison separately on the returns policy use around.Finally,carrying on the analysis with mathematics software to the model,the result indicated that,after joining the returns policy, whatever the returns price does, the overall profit of supply chain always increases, but only when the return price in the certain scope, may at the same time increase the bilateral supply chain profits, achieving the supplies chain to be coordinated.
