基于AHP-熵权法的高层建筑电气火灾风险评价

Electrical fire risk assessment of high-rise buildings based on AHP-entropy weight method

高层建筑电气火灾频繁且损失严重,深入研究电气火灾风险评价方法可以预防电气火灾的发生。针对目前高层建筑电气火灾风险定量评价研究较少,单一的层次分析法(AHP)受主观影响因素较大,评价结果有一定偏差的问题,提出了基于AHP-熵权法的高层建筑电气火灾风险评价方法。首先,建立评价指标体系,运用AHP和熵权法求出指标综合权重;其次,结合模糊评价法建立了模糊综合评价模型;最后,运用该评价模型对沈阳某高层建筑进行电气火灾风险评价,并根据评价结果提出相应的改进措施。

Electrical fire in high-rise buildings is frequent and the loss is serious,so in-depth research on electrical fire risk assessment methods can prevent the occurrence of electrical fires.At present,there were less researches on quantitative assessment of electrical fire risk in high-rise buildings,the single analytic hierarchy process(AHP)was affected by subjective factors and the assessment results had some deviations,therefore a new method of electric fire risk assessment of high-rise buildings based on AHP and entropy weight method was proposed.Firstly,the evaluation index system was established,and the index comprehensive weight was calculated by using AHP and entropy weight method.Secondly,the fuzzy comprehensive evaluation model was established by combining the fuzzy evaluation method.Finally,the evaluation model was used to evaluate the electrical fire risk of a high-rise building in Shenyang,and the corresponding improvement measures were put forward.
