摘要
为提升中国列车运行控制系统-3（CTCS-3）的可靠性,建立一个种新的基于失效模式与影响分析（FMEA）与消去与转换法-Ⅲ（ELECTRE-Ⅲ）的风险评估模型。首先利用直觉模糊数（IFNs）刻画不确定评估信息,利用ELECTRE-Ⅲ构造不同潜在失效模式（PFMs）间的级别高于关系,进而将PFMs的风险水平排序;然后进行案例分析,并与传统FMEA方法、加权平均集结算子、多准则妥协解排序法（VIKOR）、逼近理想解排序法（TOPSIS）等方法对比。结果表明：基于FMEA与ELECTRE-Ⅲ的CTCS-3的安全评估模型的稳健性较强,并能有效克服指标间异质性的影响。
For the sake of enhancing the reliability of CTCS-3 train control system,a novel risk assessment model based on FMEA and ELECTRE-Ⅲ is built proposed. In the model,IFNs is utilized to characterize the uncertain information,and ELECTRE-Ⅲ is introduced to construct the outranking relations between PFMs,and then the ranking of PFMs based on risk level is achieved. A case study is introduced to compare the proposed model with the traditional FMEA,the weighted arithmetic average aggregation operator,VIKOR and TOPSIS. The results demonstrate that the model built by the authors of this paper has strong robustness and can effectively overcome the influence of the heterogeneity among the indexes.
