基于组合赋权与改进云模型的航空装备风险评估方法
Research on Risk Assessment Method of Aviation Equipment Based on Combined Empowerment and Improved Cloud Model
摘要
Abstract
To assess the faults risk of aviation equipment and to reduce the randomness and ambiguity in risk assessment,a risk assessment method for aviation equipment with improved cloud model is proposed.First,experts construct fault trees based on historical fault data and experience,calculate the subjective and objective weights using AHP and CRITIC method respectively,and fuse them to obtain the comprehensive weights;Then,combined with the cloud model,the parameters of the fault event sub-cloud are calculated,and for the calculation of the established algorithm about the cloud model synthesis does not consider the influence of the data dispersion degree on the entropy and super-entropy,additional adjustment coefficients are added to the calculation of the entropy and super-entropy synthesis of the cloud model,which makes the evaluation results more fully describe the dispersion of the data and better meet the reality.Finally,the validity of the model was verified with a risk assessment of a take off warning system for a certain type of aircraft.关键词
