Improved Mond process used for safety evaluation

The invention discloses an improved Mond process used for safety evaluation. The improved Mond process for safety evaluation includes steps of 1) acquiring safety information and identifying and classifying the acquired safety information, determining substitution events according to fault tree analyzing method, analyzing various reason events including basic events and non-basic events layer by layer and establishing a fault tree according to the analysis; 2) determining structure importance coefficient of each basic event and sequencing the structure importance of all the basic events from big to small; 3) determining 'suggest coefficient' range of the basic events by the Mond process during safety evaluation; and 4) determining value of 'adoption coefficient' within the given 'suggest coefficient' range, preferably taking high values of the large structure importance coefficients, and taking small values of the small structure importance coefficients. The purpose of realizing rationality of safety evaluati
