摘要
传统机场机坪运行评价方法在确定指标权重方面存在不足,而模糊评价法在确定隶属度时主观判断较多。结合通用机场机坪运行特点建立评价指标体系,采用变权和相对差异函数的方法对通用机场机坪运行安全风险进行评估。首先运用变权理论对各评价指标的常权进行调整,体现单个指标对评价结果的影响;然后利用相对差异函数确定单因素对各安全等级的隶属度,消除模糊评判隶属度向量受专家经验和认识的局限性;最后对风险值进行计算,得出通用机场机坪运行风险水平。结果表明:该机场机坪运行风险水平计算结果正确,该方法能客观反映风险源对风险评估值的影响。
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.
