Abstract Aiming at the problems of excessive risk factors and uncertainties in risk assessment, a risk assessment method based on factor analysis and cloud model is proposed. Firstly, the dimension reduction effect of factor analysis (FA) method and its implementation process are introduced to simplify the risk assessment indicators. Then, cloud model is adopted to replace membership function. A risk assessment method based on cloud model is proposed, which solves the problem of fuzziness and randomness of indicators. Finally, the effectiveness of the proposed method is verified by an example.
