基于总量折扣的一对多供应链定价协调研究

Study on Pricing Strategy of One-to-many Supply Chains Based on Volume Discount

考虑由单个供应商和多个不同零售商组成的供应链,运用Stackelberg博弈模型,针对一般的价格弹性需求函数,研究了供应商如何设计由不同的总量折扣点组成的折扣表对供应链进行协调的问题。分析表明:在一定条件下,不同的零售商面对具有不同折扣点的折扣表时,给予折扣前需求量大的零售商选择的折扣点不小于需求量小的零售商选择的折扣点,在此基础上,将问题转化为带约束的非线性规划模型,并给出了相应的启发式算法。数值分析表明,具有多个折扣点的总量折扣表具有很高的协调效率。

In this paper, considering a supply chain composed of a single supplier and multiple retailem, we used the Stackelberg model to study the coordination of the supply chain in the ease of discount tables made up of different volume discount points, then through analysis, reached some conclusions, and on such basis, converted the problem at hand into a constrained nonlinear programming model. At the end, we presented the corresponding heuristic algorithm and used a numerical analysis to show the effectiveness of the model.
