Abstract

As well as known, fixed-roof tanks are vulnerable to fire and explosion accidents. To ensure the safe operation of atmospheric vertical fixed-roof storage tanks, it is essential to conduct fire and explosion risk assessments. In order to overcome the subjectivity of traditional analytic hierarchy process, improved analytic hierarchy process, and fuzzy fault tree analysis in the risk assessment of storage tank fire and explosion, a modified analytic hierarchy process was proposed in this paper. Meanwhile, the judgment matrix of modified analytic hierarchy process was constructed based on the optimized structure importance of the bottom event of the fault tree. Then, the weight factors of all indexes were calculated to evaluate the fire and explosion risk of the storage tank with fixed roof.
