摘要
将模糊概率理论引入石化企业重大危险设备故障树分析方法中,将基本事件发生的概率描述为模糊数,利用模糊算子进行模糊故障树分析,并计算出整个系统的模糊故障率。模糊故障树分析在炼化装置的重要设备———常压炉中的应用,使风险评价结果更趋合理和科学。
This paper introduces fuzzy probability theory in fault tree analysis of important hazard equipment of petrochemical company. We described the probability values of basic events as a fuzzy number, and carried out fuzzy fault tree analysis by using fuzzy operator. At last, calculated the fuzzy probability of the entire system. The application in the normal pressure furnace, which is important equipment in refinery, makes the risk as- sessment more reasonable and scientific.
