摘要: 为提高地铁车辆故障模式危害度评估的准确性,开发基于信息公理和区间二元语义的故障模式危害度评估方法。评估过程中,将语言值作为风险因子的评估值,并考虑存在评估值为区间语言值以及评估值缺失的情况,同时为避免转换过程中信息丢失,利用区间二元语义转换语言评估信息;提出基于区间二元语义的风险因子主客观权重求解方法;结合信息公理,提出基于区间二元语义的信息量计算方法,并根据信息量,评估故障模式危害度;最后,将该方法应用于实例并与其他方法进行对比分析,验证方法的可行性和有效性。结果表明:用该方法得到故障模式的危害度符合实际情况,其结果较用对比方法得到的更加客观、准确。

Abstract: To improve the accuracy of evaluation of failure modes criticality of metro vehicle,a method based on information axiom and interval 2-tuple linguistic was worked out.In this paper,firstly,the evaluation value of risk factors adopted linguistic value,and the interval two tuple linguistic was used to deal with the linguistic value.Secondly,the subjective and objective weight of risk factors were considered simultaneously.Thirdly,the calculating method of information was presented based on information axiom and the interval two tuple linguistic,and according to the size of the information,the failure mode criticality was evaluated.Finally,the method was applied to an example and compared with other methods to verify its feasibility and effectiveness.The results show that failure mode criticality got by using the method conforms with the reality,and that the results are more objective and accurate than those obtained by using other methods.

Key words: information axiom, interval 2-tuple linguistic, comprehensive weight, failure mode, criticality evaluation
