基于层次分析法的轻轨运营系统安全综合评价指标体系研究

影响轻轨运营安全的因素很多，如何确定不同因素影响的程度和权重是轻轨运营安全评价中的关键。层次分析法可以对非定量事物进行定量分析，为轻轨运营安全评价指标权重的确定提供可行的途径。文章通过在轻轨运营安全评价中建立评价指标体系和层次结构模型，运用层次分析法构建不同层次及各类因素中全部指标的判断矩阵，通过矩阵运算和一致性检验，得到各级指标的权重及层次单排序、层次总排序。根据最终的排序结果，确定对轻轨运营安全影响较大的因素。

Research on Index System of Safety Ensuring in Light Rail Based on Analytical Hierarchy Process

Due to the mass influencing factors to light rail ensuring security, it is the most key point to determinate the indicator weight and degree. The analytic hierarchy process （AHP） can be used to carry out the quantitative analysis to the non-quantitative things, and as a feasible method, adopted for determining the weight of each index. The index system and the hierarchy structure model are established in the assessment of light rail ensuring security in this paper, The judge matrix is formed with the different rank and sort factors by the AHP. The weight, the hierarchy single arrangement and the multi-arrangement are obtained through the matrix operation and uniform examination. From the final arrangement result, it concluded the main factors.
