模糊层次分析法模型在地铁区间隧道火灾风险评估中的应用

On the Application of Fuzzy Analytic Hierarchy Process to the Fire Risk Assessment of Subway Sections

针对地铁区间隧道火灾风险评估中指标关系的模糊性及层次分析法中一致性判断的缺陷,引入模糊一致性判断矩阵,有效地减小指标判断中的人为主观因素影响,并使之与层次分析法相结合,建立一种针对地铁区间隧道火灾风险评估的模糊层次分析法模型。选取某地铁隧道,综合考虑地铁区间隧道火灾风险评估体系的复杂性,对其建立模糊层次分析法模型,获取其各因素权重,结合风险指数法对火灾风险评估结果进行量化处理;通过权重分析比较得出火灾风险评估中较薄弱的环节,指导地铁设计、施工及运营全寿命期消防安全工作的正常进行。

Against the deficiency of the disagreement assessment of the fire risk between subway sections, of fuzzy and hierarchy methods of index relationship of the fire this paper introduces the fuzzy consistent matrix to lesser the subjective factors in index judgments and integrate it into a analytical hierarchical method to set up a fuzzy analytical hierarchical mode to assess the fire risk between subway sections. The mode is based on a certain subway and on the complex of the fire risk assessment system. The parameters of factors are obtained and the results of index of the fire risk assessment are calculated. The deficiency of this fire risk assessment is found and the research results are useful for the construction of a subway.
