摘　　要：以某化工企业中毒或窒息事故为例,建立以动态故障树为基础的事故模型,并得出导致事故发生的基本事件.首先,采用BDD法分别对模型中的静态子树进行定性和定量分析,然后,采用马尔科夫链法对动态子树进行分析,得出事故后果失效概率以及各事件结构重要度,并基于对事故进行分析得出的结果,进一步提出有关事故的预防措施.Taking the poisoning or suffocation accident of a chemical enterprise as an example,an accident model based on dynamic fault tree is established,and the basic events leading to the accident are obtained.Firstly,BDD method is used to analyze the static subtree qualitatively and quantitatively,and then Markov chain method is used to analyze the dynamic subtree.The failure probability of accident consequence and the importance of each event structure are obtained.Based on the analysis of the accident,further preventive measures related to accidents are proposed.
