摘　　要：城市轨道交通作为引领城市发展的重要战略引擎,轨道线网合理布局是其建设的基础。为检验线网布局的合理性,本研究构建了具有典型性的城市轨道交通指标体系,基于层次分析法和均方差法的组合赋权法确定各指标相对权重,基于TOPSIS法和灰色关联法提出TOPSIS-GRA轨道交通线网评价方法,并将TOPSIS-GRA法应用到具体实例中进行验证。研究表明,对比单独使用TOPSIS法和灰色关联分析结果,发现各方案之间排序一致,说明该方法具有可行性;TOPSIS-GRA方法融合了TOPSIS法和GRA法在整体性和相关性分析方面的优点,在对轨道交通线网方案进行评价时能给出较为客观的评价结果。Urban rail transit is an important support in the development of city,and the rational layout of the rail network is the basis for its construction.In order to test the rationality of the line network layout,Firstly,this research constructed a typical urban rail transit index system,and determined the relative weight of each index based on the combination weighting approach integrating the AHP method and the mean square difference method.Secondly,an evaluation method integrating TOPSIS method and Grey Relation Analysis is proposed,and a specific example is applied to verify the proposed method.It is found that the rankings of the projects are consistent compared to the results of using the TOPSIS method and the grey relational analysis,indicating that the method has feasibility.In addition,objective evaluation result can be given through TOPSISGRA evaluation method integrating the advantages of the TOPSIS method and GRA in terms of integrity and correlation analysis when evaluating the rail transit network plan.
