基于模糊重心的建筑火灾危险性评价

Buildings' Fire Risk Assessment Based on Fuzzy Gravity Center

为了改善模糊综合评判中专家打分的过程及指标值被淹没的现象,提高评价的准确程度,通过采用模糊区间的打分格式后而提出一种用于火灾风险评价的模糊重心评价法·根据实际调研情况,建立火灾评价指标体系,对某商场的火灾危险状况进行了评价,得出了其火灾危险性大的结果,与该商场的实际情况相符·同时,与其他评价方法相比,模糊重心评价法得到的评价信息更丰富,可信度更高,其指标重心的排序结果可以为安全管理工作提供充分的依据·

A new fire risk assessment in terms of fuzzy gravity center is put forward to make the assessment result in connection with fuzzy intervals so as to improve the traditional marking procedure by experts, during which the given indices for assessment were submerged. At the same time, the accuracy of assessment can be guaranteed. According to the actual survey of a marketplace, a system of fire risk assessment indices is established and used to assess its fire risk. A high mark is given to it and conforms with the actuality, showing a serious fire hazard. Compared with other assessment methods, more information and higher reliability can be got by the method in terms of fuzzy gravity center. In addition, the result of index gravity centers ranking will be beneficial to fire safety management.
