城市公交线网等级评定的物元分析模型

Matter Element Analysis Model for Grade Evaluation of Urban Public Traffic Network

针对城市公交线网等级评定问题,利用可拓学中的物元分析理论进行了研究。在考虑城市公交系统多种因素的基础上,构建了城市公交线网评价的指标体系。并在定义评价等级的基础上,通过定量分析为主、定性分析和定量分析相结合的方法,建立了城市公交线网等级评定的物元分析模型。通过计算其关联度,给出定量的数值来表示评定结果,将公交网络的多层次评价转化为单级评价,评价值能够简明准确地反映出城市公交发展现状。应用结果表明该法科学合理、简单易行,为多层次评价问题提供了一种合理可行的方法。

The grade evaluation of urban public traffic network was researched by matter element theory in extenics.Considering each factor of urban public traffic network,the evaluation index system of urban public traffic network was set up.Based on the definition of evaluation grade,a matter element model of the grade evaluation to assess the urban public traffic network was built up by combining quantitative analysis with qualitative analysis,with quantitative analysis on the former.The quantitative number values to express evaluation result were given by calculating relational degree.The multi-ingredient urban public traffic network assessment was transformed into the single-object decision and the evaluation values can directly show the integrative level of the urban public traffic network.The application result shows that it is simple and practical which could be a reasonable and effective method for the multiple attribute evaluation problems.
