摘要
为高效地评定地铁车站消防安全状态,从四个维度构建地铁车站消防安全评价指标体系。通过改进的CM-AHP法与因子分析方法对指标赋权,并基于最小二乘法组合优化。根据修正后的云数字特征生成云模型,进而集成浮动综合等级模型。结合指标的等级隶属度与组合权重获得综合评价云模型,通过云图直观展示车站消防安全状态对各综合等级云的依赖程度和发展趋势。
In order to effectively evaluate the fire safety status of metro stations,the fire safety evaluation index system of subway stations is constructed from four dimensions.The weights of indexes are determined by the improved CM-AHP and factor analysis,and the combination optimization is based on the least square method.The cloud model is generated according to the modified digital characteristics,and then the floating comprehensive level model is integrated.The comprehensive evaluation cloud model is obtained by combining the grade membership degree and combination weight of the indexes.Through the cloud map,the degree of dependency on the comprehensive level cloud and the development trend of the fire safety state can be seen intuitively.
