AHP-TOPSIS法在地铁车站方案选择中的应用

利用层次分析(AHP)法和TOPSIS法相结合的方法,建立地铁车站方案比选和排序的数学模型,确定大连地铁胜利广场车站的施工方案。采用专家调查确定相关影响因素,通过AHP法计算各指标的权重,并进行层次总排序,再用改进的TOPSIS法进行评价指标值的规范化和排序计算,最终确定现场施工方案。通过采用AHP法和TOPSIS法相结合的方法,避免了TOPSIS法在多因素分析中的繁琐运算,同时在一定程度上克服了AHP计算结果的主观性,使实际地铁车站方案的选择更加科学和合理。

Application of AHP-TOPSIS in Scheme Comparison of Subway Stations

By combining Analytic Hierarchy Process (AHP) and TOPSIS, this paper establishes a mathematic model for the scheme comparison of subway stations to choose the construction scheme for Shengli square Station of Dalian metro. This paper determines related effect factor by expert surveys, calculates each index through AHP, makes total hierarchy arrangement and applies the modified TOPSIS to normalize and sort the evaluation index value. Finally, the construction scheme is chosen. With the combined use of AHP and TOPSIS, avoiding tedious arithmetic of TOPSIS in multivariate analysis, at the same time overcoming to some extent the subjectivity of the AHP calculation results,so the choice for the construction scheme of subway stations is more scientific and reasonable.
