Research on optimization of safety management in oil depot based on FTA

Based on FTA of safety-system engineering and analysis of risk or hazard factors of oil depot, the fault tree factor table of fire and explosion is determined and the fault tree is established. By means of Boolean algebra simplification, the minimum path sets of the system are achieved. And major hidden troubles of fire and explosion in oil depot are found out on the basis of the analysis about structure importance degree of each basic event. According to the minimum path sets of the fault tree, the control solutions are proposed to prevent the oil depot from fire and explosion. In the end, the most optimizing decision of safety management in oil depot is made on the basis of the costbenefit assessment of each solution.
