空中交通管理系统安全绩效评估模型研究

客观准确的安全绩效评估,可以反映出空中交通管制系统运行的安全状况,并识别出安全管理存在的薄弱环节.从管制员、空中交通管制设备、环境、管理四方面找出影响系统安全运行的过程性指标,将过程性指标与结果性指标相结合构建空中交通管制系统安全绩效评估指标体系;在模糊物元分析法的基础上,对隶属度函数的确定方法进行改进,建立基于改进的模糊物元分析法的空中交通管制系统安全绩效评估模型;利用该模型对某空中交通管制单位的安全绩效进行评估,评估结果能够反映出该单位的安全状况,并指出应当改进的环节.结果表明:本模型可以对空中交通管制系统的安全绩效作出综合评判,并可以对空中交通管制系统的安全性进行量化描述.

Research On Safety Performance Assessment of Air Traffic Control System

Objectively and accuratelySevaluatingSthe safety performance can reflect the safety status of ATC system operation, and identify Sthe weak links in safety management.Finding key process indicators whichSaffect the systemSoperation safetySfrom theSfour aspectsSSof controllers, ATC equipment, environment and management, combining process index and result index to establish the safety performance evaluation index system of air traffic control system.On the basis of fuzzy matter-element analysis, the membership function is improved, and establishes the model ofSATC system safety performance evaluationSbased on the improved fuzzy matter-element analysis method. Finally, the evaluation results of evaluating ATC unit safety performance reflect the safety status of the ATC unit, and I find out the segment through the results which should be improved.
