基于IAHP和Vague集的高层建筑火灾风险评价

Fire Risk Evaluation of High-Rise Buildings Based on IAHP and Vague Sets

针对高层建筑火灾风险评价存在模糊性和难以分辨性的问题,基于高层建筑火灾特点,从防火系统、灭火系统、消防施救设施、安全疏散和消防安全管理五个方面构建了高层建筑火灾风险指标评价体系。采用区间层次分析法(IAHP)给各指标赋权,结合Vague集理论建立了高层建筑火灾风险的改进模糊综合评价数学模型。最后进行实证分析,结果表明该方法能够有效反映高层建筑火灾风险情况。

In order to carry out fire risk evaluation on the high-rise building, based on the characteristics of fire risk in high-rise buildings, an index evaluation system of fire risk in high-rise buildings is established from five aspects including fire prevention system, fire extinguishing system, safety evacuation, fire rescue facility and fire safety management. A melioration fuzzy comprehensive evaluation model for high-rise building fire risk assess- ment is then established by use of the interval analytic hierarchy process （IAHP） with all indices ＇weights in proper place and the Vague sets theory. Finally, the corresponding empirical analysis is conducted so as to verify the theory concerned. Results prove that the proposed method can accurately and effectively reflect the actual situation of the high-rise building fire risk.
