具有Stackelberg博弈特征的供应链定价协调

The Coordination of Pricing in A Supply Chain with Stackelberg Game

针对某些供应链在定价决策过程所具有的Stackelberg博弈特征,利用二层规划构建了供应链定价均衡模型,研究了供应链定价协调模型,并给出了批发价格折扣契约这种协调机制,为求解二层规划模型,给出了基于混沌搜索的启发式算法,最后用实例验证了结论。研究表明二层规划可以很好的用来模拟Stackelberg博弈,价格折扣契约能够协调供应链。

For the Stackelberg Game of pricing decision process in some supply chains, the supply chain pricing equilibrium model is constructed by means of bi-level programming. The coordination model of pricing is studied, and the price discount contract as a coordination mechanism is presented. The heuristics algorithm based on chaos-search is presented for solving the bi-level programming. At last, the conclusion is confirmed by a numerical example. The study shows that the bi-level programming can well simulate the Stackelberg Game, and price discount contract can coordinate the supply chain.
