摘　　要：在借鉴我国众多城市轨道线网综合评价指标的基础上,从运营效果、网络结构、社会效益、战略发展和可实施性5个方面建立了轨道交通线网综合评价指标体系。以备选方案为论域集,以各方案指标属性值构建了线网方案评价初始决策矩阵,采用[0,1]线性变换将其进行归一化处理,形成了标准化决策矩阵。充分考虑专家经验、决策者偏好以及数据本身蕴含的信息,采用AHP法与熵权法确定了指标的综合权重,构建了加权标准化决策矩阵。运用运筹学中的TOPSIS法确定了线网正负理想方案,通过计算各方案与正负理想方案的贴近度对比了线网方案的优劣。运用该方法对西安轨道交通线网4个预选规划方案进行了评价,推出了最优方案。结果表明:该方法计算简单,决策科学,具有较好的应用前景。Based on referencing the comprehensive assessment index of rail transit network of Chinese cities, a comprehensive assessment system of rail transit is proposed in respect of operational effect, network structure, social benefit, strategic development and implementation performance. Taking the network schemes as the domain set, the network scheme is established based on the attribute values of indexes in each scheme to assess the original decision-making matrix, and the matrix is normalized to the standard decision matrix by [0, 1 ] linear transformation. Give full consideration of the expert experience, the decision-maker＇s preference and the data implied information, the comprehensive weights of the indexes are determined by the AHP and entropy weight method, and the weighted standardized decision-making matrix is constructed. The negative ideal schemes are determined based on TOPSIS in operational research, and the pros and cons of the line network schemes are compared by calculating the close degree of the programs to the positive and negative ideal schemes. This method is applied to assess Xi＇an urban rail transit network planning, and the best one in 4 network schemes is chosen. The result shows that this method has a better application prospect for its simple calculation and science decision-making.
