摘要
为了有效预防、控制和减少建筑火灾事故的发生,采用模糊理论和证据推理理论耦合的方法,从火灾发生的可能性和后果的严重性出发,对建筑火灾风险进行二维度量的综合评估研究,构造出Fuzzy-DS模型。以某建筑为实例,对其使用该模型进行评估。研究结果表明:该建筑火灾风险的效用值为0.298 4,对应风险水平为"中",并运用敏感性分析验证了模型的鲁棒性,验证了该模型的有效性。
In order to effectively prevent,reduce and control the occurrence of building fire accidents,starting from the occurrence possibility and the consequence severity of fire,the comprehensive assessment research on building fire risk in the two-dimensional metric was carried out by using the coupling method of fuzzy theory and evidence reasoning theory,and a Fuzzy-DS model was constructed. Taking a certain building as an example,the assessment was carried out by using this model. The results showed that the utility value of fire risk for this building was 0. 2984,with the corresponding risk level of medium,and the robustness of the model was verified by using the sensitivity analysis.
