摘要
研究了收益共享契约下,单供应商和多个价格竞争的零售商构成的供应链系统的均衡及协调问题.基于经济博弈理论的最新进展——超模博弈理论,证明了价格敏感的随机需求下零售商间的价格竞争一定存在纯策略纳什均衡,分析了均衡的特点,并给出了存在唯一均衡的条件;基于以上分析,对契约机制的设计进行了优化,既保证各方接受对契约的优化,又可实现多赢和系统协调.
Equilibrium and coordination of system are investigated in a two-echelon supply chain with one supplier and many price-competing retailers. Based on supermodular game, the existence of pure-strategic Nash equilibrium is proved, the characterizations of the equilibrium are analyzed, and the conditions of existing unique equilibrium are also given. Based on above analysis, an improvement design of the revenue-sharing supplier and retailers and realize supply contracts is provided, which can increase the profits of the chain coordination.
