重大危险源风险评价研究

Risk Assessment Study on Major Hazard Sources

运用马尔可夫过程研究了化工企业重大危险源事故发生的概率,在基于马尔可夫事故概率假设模型的基础上分析了化工企业事故概率数学模型。对重大危险源事故易发性、事故严重度、固有危险性及危险等级进行了评价,并进行了实例计算。

Markov process is used to conduct study on the probability of accident happening because of major hazard sources in chemical businesses. Based on the assumed model of Markov fault probability, mathematical model of fault probability in chemical businesses is analyzed. Evaluations are conducted on the possibility of major hazard source accidents, severity, inherent risk and risk grade and the practical calculations are also conducted.
