针对机坪安全风险较为严峻的问题,通过剖析机坪作业安全影响因素及事故原因,从机坪设施设备安全状况、空防保障系统安全状况、机坪作业人员管理状况、机坪车辆管理状况、机坪现场指挥协调状况、机坪安全综合管理系统状况6个方面构建了机坪安全风险评价指标体系。根据模糊数学理论建立了机坪安全风险多级模糊综合评价模型,并对模型进行了实例验证。该方法可以给出机坪的整体安全风险等级和各评价指标对机坪安全风险性的影响及大小。 Aiming at the serious problem of apron safety risk, by analyzing the factors influencing the safety of apron operation and the causes of accidents, this paper analyzes the safety conditions of apron equipment, the safety of air defense system, the management status of apron workers, The status of command and coordination at the ramp, the status of the apron safety management system, the index system of apron safety risk assessment was constructed. According to the theory of fuzzy mathematics, a multilevel fuzzy comprehensive evaluation model of apron safety risk is established, and the model is verified by examples. The method can give the overall safety risk level of the apron and the impact and size of each evaluation index on the safety risk of the apron.
