为比选长输管道线路路由方案,定量分析各方案的适应性,提出了一种基于“层次分析法—逼近理想解排序法”(Analytic Hierarchy Process-Technique for Order Preference by Similarity to Ideal Solution,AHP-TOPSIS)的线路路由比选方法...为比选长输管道线路路由方案,定量分析各方案的适应性,提出了一种基于“层次分析法—逼近理想解排序法”(Analytic Hierarchy Process-Technique for Order Preference by Similarity to Ideal Solution,AHP-TOPSIS)的线路路由比选方法。以陕京二线输气管道大盂—石家庄分输站段路由方案比选为例,选取投资估算、隧道穿越情况和通过活动断裂带情况等10个指标,确定线路路由比选指标体系,构建目标层—准则层—方案层的递阶层次模型;通过构建AHP-TOPSIS评估模型,计算各指标权重并排序,构建加权规范化决策矩阵,计算各方案与理想方案的相对接近程度,从而确定最佳方案。分析结果表明:投资估算、隧道穿越情况和通过活动断裂带情况对线路路由方案的选择影响较大;通过定量计算,路由方案中南线方案更优,与工程实践也相符合。工程实例证实AHP-TOPSIS法能够用于长输管道线路路由比选,为最佳方案的选择提供依据。展开更多
