| 摘 要： | 针对地铁系统的使用性能和结构性态综合评价的复杂性、模糊性和缺乏合理评价方法,采用主成分分析法,选取影响地铁系统安全程度的主要指标,借助Matlab数学工具对地铁系统的使用性能和结构性态进行综合评价.分析表明：主成分分析法用于地铁系统安全程度的综合评价是可行的,而且能客观地反映评价指标对综合评价值影响的强弱,具有特有的优越性.

| Abstract: | Due to the complex,fuzzy and unreasonable evaluation methods of synthetical performance evaluation of metro system performance characteristics and structural behavior,the principal component analysis(PCA) and Matlab software are applied and several main evaluation indices influencing safety degree of metro system are introdeced.The results indicate that the PCA is feasible and effective applying to synthetically evaluating the metro system safety,which could reflect the effects of indices on synthetical eva... |
