模糊系统分析在山地城市商业建筑火灾中的应用

Application of fuzzy system analysis for business buildings fire in mountain cities

以我国山地城市大中型商业建筑的特大火灾事故为例进行研究,对火灾起火情况进行统计调查,构建模糊系统模型进行分析。由于火灾数据缺乏,因此采用了火灾事件年统计概率隶属函数和诱发火灾事件概率隶属函数的确定方法。通过模糊系统故障树分析,确定出顶事件发生概率的模糊数,然后对系统进行模糊重要度分析,最后进行山地城市大中型商业建筑模糊系统决策分析,为火灾防治提供有效的依据。

According to the investigation to especially serious fire accident cases in big and middle-scale commercial buildings in mountain cities, a research of built up. The member functions of the statistics fire was made. In the analysis of fire, a fuzzy system model was probabilities for especially serious fire accidents and the basic events of in the model were used in order to overcome the difficulty that fire data is scare. Through the analyses of the fuzzy fault tree, the fuzzy number of the importance, a strategic decision of the fuzzy fire fire in big and middle-scale business buildings ty for the top event was protection system was made. in mountain cities. given. Based on the analysis of fuzzy It will provide the basis for preventing
