摘要
主要讨论在行星齿轮变速箱方案设计过程中已经获得多个相对优秀的方案后，如何合理地进行评判决策出最佳方案基于模糊理论，建立了行星齿轮变速箱方案优选的模糊评判数学模型，并用实例进行计算说明。
In process of schemes design of epicyclic gearbox, lots of better schemes have been gotten, how to judge the scheme and get the best scheme is discussed. Based on fuzzy theory, sets up fuzzy judgment mathematic model of scheme, and by the example illustrating, the mothed is science.
