摘　　要：本文对模糊环境下两个竞争零售商供应链系统的最优决策及协调问题进行了研究。首先分析比较了在一体化决策和分散化决策下受模糊变量影响的两竞争零售商的最优决策,然后提出了收益共享契约协调模型,并通过模型求解得到了收益共享契约成立的条件,结果表明收益共享契约成立不仅与收益参数有关,还与生产成本c、需求价格弹性系数βi(i=1,2)和市场规模ai(i=1,2)的期望值以及生产成本c和竞争对手需求价格弹性β2的乐悲观值有关。最后通过数值实验分析了收益参数及模糊变量取值对收益共享契约模型中供应链系统各成员期望利润的影响。For a supply chain system with two competing retailers under fuzzy environment, the problems about the optimal pricing decisions and the coordination of supply chain were researched. Firstly, the optimal pricing decisions of two competing retailers under decentralized decision and centralized decision which were affected by the fuzzy variables were analyzed and compared. Then the coordination model of revenue sharing contract was proposed, and the conditions which could establish revenue sharing contract were obtained by solving the model.The result suggest that the establishment of the revenue sharing contract not only relates to revenue parameters, but also to the expectations of production costc, the price elasticity of demand βi（i=l,2）, market size ai（i=l,2） and the pessimistic value and optimistic value of production cost c and Competitor＇s price elasticity of demand β2. Finally a numerical analysis was adopted to test the effect of revenue parameters and fuzzy varia- bles on expected profits of each member in the contracted supply chain.
