基于属性识别模型的建筑物火灾危险性评价

Hazard assessment of building fire based on attribute recognition model

建筑物是一个集人员与财产于一体的系统,一旦发生火灾,后果不堪设想。利用层次分析法并结合属性识别理论,建立了建筑物火灾危险性的层次-属性识别模型。聘请10位专家对建筑物火灾危险性的评价指标体系的24项指标进行评价,利用层次分析法确定各评价指标的权重以计算综合属性测度区间,应用置信度准则和评分准则对建筑物火灾危险性进行属性识别。并对某大学3#教学楼的火灾危险性进行了评价,得出火灾危险性等级为危险性较小,安全性较好,也说明了该建筑物需要进一步采取安全措施,加强安全管理,提高其安全程度,避免火灾事故的发生。

The building is a collection of person and property in the integrated system, and the consequence of fire is unimaginable. In this paper the research on attribute recognition theoretical model was introduced. Attribute recognition theoretical model of building fire was set up by making use of analytic hierarchy process. For decision-makers, it is often the case that the assessment of fire of building involves unexpected factors of different nature, which makes the assessment a multi-index complicated one. The assessment method has now turned to be a key problem to the sustainable control of fire of building. The index system of building fire was evaluated by ten specialists , the synthetic attribute meas- urement interval was calculated by the analytic hierarchy process, and the confidence criterion and the score criterion were used to recognize the fire hazard of building. To test the effectiveness of the method, 3# teaching building of a college was chosen as a case study, which indicated that the fire hazard of 3# teaching building of college was less ,also indicated that the buildings were needed to take further measures to improve the safety degree, thus to avoid fire accident. The results showed that the model could provide a new way and means for fire hazard study.
