摘要
为准确评价城市综合体建筑火灾风险等级,考虑到火灾风险影响因素的复杂性和不相容性,提出一种基于组合权和物元分析理论的城市综合体建筑火灾风险评价方法.首先,根据综合体建筑火灾特点与灾害机理,按人-机-料-法-环5要素确定评价指标体系,采用层次分析法(AHP)和熵权法计算指标组合权重;其次,针对评价的模糊性和不确定性,通过物元变换建立评价的物元体系,即确定火灾风险评价的经典域、节域和待评物元,通过计算等级贴近度确定综合体建筑火灾风险等级;最后,以武汉市某大型综合体为例,按照该方法确定该建筑火灾风险等级.结果表明,该综合体建筑火灾风险为安全,符合实际情况;与用于一般建筑火灾风险的其他评价方法相比,更为准确客观、简便易行.
To get scientific and objective assessment of the grade of the fire risk of large commercial complex building project, considering the complexity and incompatibility of factors in the assessment, a method based on combination weight and matter element analysis was developed. Embarking the characteristics and disaster mechanism of fires in large commercial complex building, a fire risk assessment index system was established according to 4 M1 E(man, machine, material, method and environment). AHP and entropy weights method were used to calculate combining weights. Considering the fuzziness and randomness of the fire risk assessment, the matter element system of fire risk assessment was established based on the matter element transform, which constructs the matter-element to be evaluated and standard one. The grade of the fire risk of large commercial complex building is determined by asymmetric closeness. Furthermore, the method was applied to a certain project as an example. The calculation results are closer to reality and the method is simpler, which conforms with the results obtained by conventional methods.
