| description | The traditional assessment method of airport apron operation has the disadvantage of determining the index weight,and there are too many subjective judgment for membership degree determining in the fuzzy evaluation method. In combination with the operation characteristics of general airport apron,the assessment index system is established,and the variable weight and relative difference function method is used to assess the safety risks of general airport apron operations. Firstly,the variable weight theory is used to adjust the constant weight of each evaluation index. And then the relative difference function is used to determine the single factor on membership degree of each safety level,so as to eliminate the limitation of fuzzy adjustment membership vector given by experts’experience and knowledge. Finally,the risk value is calculated to obtain the risk level of airport apron operation. The results show that the risk level calculation result is correct,and the proposed method can reflect the impact of risk sources on risk assessment value objectively. |
