为科学的评价列车运行控制系统仿真的可信度,改进模糊层次分析法FAHP (Fuzzy AHP),使其更适合评价列车运行控制系统仿真。首先提出根据列车运行控制系统仿真目的不同而进行不同仿真层次的划分,分析确定影响仿真目的可信度的具体指标因素;然后请相关领域内不同研究方向的专家采用三角模糊方法对影响指标因素进行评判,取其平均值构造三角模糊一致判断矩阵;接着使用 FAHP计算各因素的模糊权重值,并进行去模糊化处理,获取各层次模块最终的权重值;再根据各层次模块的权重值及可信度按层加权计算获取列车运行控制系统仿真的可信度。根据不同仿真目的划分层次结构,确定影响指标因素,具有更强的针对性,以领域内多个不同研究方向专家的评判平均值构造三角模糊矩阵,可以更好的降低个人喜好和知识层面不同带来的偏差,加之FAHP方法考虑了人们对复杂事物判断的模糊性,能够更好地克服人为主观判断、偏好给决策带来的影响,因而更具有合理性。

While the credibility of the simulation system is guaranteed,the correctness of using the simulation system for different purposes can be ensured.In order to evaluate the simulation credibility of the train opera-tion control system,the fuzzy analytic hierarchy process (FAHP)was appropriately improved to meet the eval-uation requirements in the file of the train operation control system.Firstly,according to the different simula-tion purposes,simulation of the train operation control system was divided to different levels.Secondly,the factors influencing system credibility were j udged to get the triangular fuzzy values by experts in different re-search directions in the field of train operation control systems,furthermore their average values were calculat-ed to structure the triangular fuzzy consistent j udgment matrix.Thirdly,fuzzy weights of the influencing fac-tors were calculated with FAHP,and then they were dealt with from fuzzy to precise.There is stronger perti-nence in the way that according to different simulation purposes the system hierarchy is divided and the influen-cing factors are determined.The bias resulted from personal preferences and knowledge levels can be reduced by the average triangular fuzzy matrix made by experts in different research areas.Since FAHP has considered the fuzzy characteristic existing in people’s j udgment of complex things,the method can better overcome sub-j ective effects and so is more reasonable.
