二层供应链网络均衡模型的研究

摘要

利用均衡理论和二层规划理论来研究供应链网络均衡问题.针对供应链网络中上下层成员之间具有的Stackelberg博弈特征以及同层成员之间具有的非合作博弈特征,构建了二层供应链网络的均衡模型,该模型实际上一个均衡约束的二层规划问题.此外,为了使得供应链网络在整体上实现最优,本文还在模型中引入回收契约以协调供应链网络.最后,利用罚函数法对模型进行了求解,算例分析说明了模型的合理性和有效性.%The supply chain network equilibrium model is researched by using the theories of equilibrium and bilevel programming in this paper. According to the characteristic of Stackelberg Game in the upper and lower level as well as the Non-cooperative Came in the same level of supply chain network, a bilevel supply chain network equilibrium model is constructed, which actually is a bilevel programming with equilibrium constraints problem. In addition, in order to realize the optimization of supply chain network on the whole, the buy back contract is introduced to coordinate the supply chain network. Finally, the method of penalty function is used to solve the model, and the rationality as well as the effectiveness of our model are illustrated by a given example.
