摘要
机坪电动特种车辆运行安全风险评估是保证特种车辆稳定运行、降低航班延误率的基础。目前电动特种车辆运行安全评估尚未有一套合理科学的评估体系,因此提出一种改进隶属函数的模糊综合评估方法。通过分析机坪特种车辆特有的交通环境,首先建立电动特种车辆安全运行指标体系,运用层次分析法计算指标权重,并用改进的合成隶属函数方法确定隶属度,最后用模糊综合评估方法对电动特种车辆运行安全做出评估。验证结果表明了该方法提高了评估结果的精确度,解决了电动特种车辆运行安全评估的不系统、不科学的问题。
The safety risk evaluation for the electric special vehicle running on airport apron is the basis to ensure the stable running of special vehicle and reduce the flight delay rate.At present,it hasn′t a set of reasonable and scientific evaluation system for the running safety assessment of the electric special vehicle,so a fuzzy comprehensive evaluation method with improved membership function is proposed.The exclusive traffic environment of the special vehicle running on airport apron is analyzed to set up the safety running index system of the electric special vehicle.The analytic hierarchy process(AHP)is used to calculate the weight of index.The improved membership function synthesis method is adopted to determine the membership.The fuzzy comprehensive evaluation method is employed to evaluate the running safety of electric special vehicle.The validation results show that the method can improve the accuracy of the evaluation result,and solve the problems of poor?systematicness and poor?scientificity evaluation for running safety of the electric special vehicle.
