Application of Catastrophe Evaluation Method in Risk Assessment of SMS in Civil Aviation

Aimed at the problems of needing to determine the weights of index system in most comprehensive evaluation methods of risk assessment in civil aviation, and the calculation was too complicated; catastrophe evaluation method was applied to the risk assessment of SMS in civil aviation. Indicators were analyzed and sorted, and then the standard of the bottom indicators was performed. The ultimate catastrophe evaluation values were obtained by the normalization formulas. The calculation of MatLab eliminated the defect of the much higher catastrophe evaluation values and made the converted values more practical. At last, the example verified the feasibility, validity and practicality.
