Abstract

In order to solve the problem of mutual influence of aviation safety risk evaluation indexes, an evaluation method based on fuzzy cognitive map (FCM) and grey relational analysis (GRA) (FCM-GRA) is adopted. The method takes GRA as the main process of evaluation, uses fuzzy cognitive map to express the influence relationship between indicators, realizes the index weighting, and determines the optimal scheme ranking by calculating the grey correlation degree. This method makes up for the shortcoming that GRA can not represent the interaction between evaluation indexes alone. Finally, the method is used to rank the aviation safety risk of each unit, which provides some decision-making reference for the higher authorities to guide the aviation safety risk of each unit.
