摘　　要：指出在公交线网优化时不同的城市面临着不同的公交问题,优化设计时对各个目标的侧重也是不一样的,针对公交优化的线性模型的特点,对模型中相关的修正系数提出应用EM主观赋权法来确定,解决了目标优化时不同等级目标权重的确定问题。It points out different public transportation problems accounting in different cities of the public transportation network optimization,and the important points aiming at different aims are different in the optimization design,aiming at the characteristics of the linear model of the public optimization,it provides that applying EM subjective weighting method to confirm on corresponding correction coefficients in the models,and solves the confirming problems of different grades aim weighting in the aim optimization.

关 键 词：线网优化 权重 EM主观赋权法
