中小城市公交系统的模糊综合评价

采用层次分析和模糊评价相结合的方法对中小城市公交系统进行综合评价。建立了分层次的综合评价指标体系,利用层次分析法确定各指标的相对权重,在确定权重时利用SPSS对专家权重意见进行了聚类分析,剔除个别离异程度较大的专家意见,使指标权重结果更为合理。以12个中小城市为样本,通过统计中小城市公交系统的指标分布规律,利用M atlab模糊数学工具箱建立了中小城市公交系统各指标的隶属度函数。建立了中小城市公交系统模糊综合评价模型,并以阜新市为例验证了方法的实践性,从评价结果中除了可以得到1个分值外,还能直观地看到公交系统隶属于各个等级的程度。 

Comprehensive Evaluation Method of Regular Transit System in Small and Medium-sized Cities

In this paper ,an analytic hierarchy process and a fuzzy evaluation method are combined and used to eval-uate urban transit systems of small and medium-sized cities .Firstly a hierarchy-based comprehensive evaluation system is developed ,and then an AHP method is used to determine the relative weight of each indicator .In this process ,SPSS software is used to carry out a cluster analysis of experts＆#39;weights ,where those weights which are far away from the resul-ting clusters are removed ,which appears to make the evaluation weights from the experts more reasonable .Furthermore , using a sample of 12 small or medium-sized cities ,the sampling distribution of the indicators of the transit systems of the small or medium-sized cities is developed and the membership function of each indicator is established through the Matlab Fuzzy Toolbox .Finally ,a fuzzy comprehensive evaluation model of transit systems of small and medium-sized cities is proposed ,which is also verified through the transit system of Fuxin City .The model can provide not only a ranking score ,but also the degree of the proximity of the transit system being evaluated to various levels .
