Multi-level Fuzzy Evaluation Method for Civil Aviation System Safety
-
摘要: 为对民航系统进行安全性评估,建立了评估指标体系和评估方法.采用模糊综合评判方法计算民航系统的管理安全度和由飞行、航空保障、维护与维修3个子系统安全度组成的人-机-环境安全度,在此基础上得出系统的综合安全度.系统的安全度被划分为5个等级,当综合安全度小于4时,表明系统并没有达到较好的安全状态.通过对评估数据的分析,可找出其中被评以很差、差或对一般的隶属度较大的因素,分析问题所在,并加以整改.Abstract: An index system was proposed for safety assessment of civil aviation systems.Fuzzy comprehensive evaluation method was used to calculate the safety degrees corresponding to management and to the human-machine-environment system composed of flight,support and maintenance subsystems.The comprehensive safety degree was obtained based on the above degrees,and divided into 5 grades.The system is not safe enough if the comprehensive safety degree is under grade 4.A further evaluation to the data can reveal the possible hints that cause the data to be evaluated as "bad" or "very bad",so that precautions can be taken accordingly.
