大型公共场所火灾风险评价指标体系(Ⅱ)——指标及其权重确定

Fire risk assessment index system for large-scale public places(Ⅱ):indexes and their weights

前文“大型公共场所火灾风险评价指标体系(Ⅰ)”得出了大型公共场所火灾事故因果分析图。现在以大型公共场所火灾事故因果分析图为基础,考虑大型公共场所自身的建筑特点和使用特点,依自上而下和自下而上相结合的原则组合得出大型公共场所火灾风险评价指标,并根据因果分析图中各基本事件与顶事件的关系以及各基本事件的统计频率值,确定指标权重,得出大型公共场所火灾风险评价指标体系。

Paper ＂Fire risk assessment index system for large-scale public places （Ⅰ）＂ presented the figure of causality analysis for fire accident in large-scale public places. Based on this figure and thinking over the characters in public place＇ s construction and use, this paper gives the index in fire risk assessment of large-scale public places according to the principle of combing the bottom-up method and the top-down method. Then, the weight of each index is given by the frequency of end-events of fault trees in figure of causality analysis and by the relationship of end-events and top-events. Fire risk assessment index system of large-scale public places is displayed finally.
