摘　　要：在评价铁路信息系统指标权重时,为了克服传统层次分析方法的局限性,提出在专家打分法的基础上,对传统的评分数据进行聚类分析,运用加权欧氏距离的聚类理论,剔除差异最大的评分,综合应用层次分析法和加权平均型综合函数,得出评价指标的权重,从而提高评价结果的可靠性和准确性,增强重要评价指标对评价结果的影响力。最后,通过实例验证该方法的合理性和可靠性。When evaluating the weighing of railway information system index, in order to overcome the limitation of traditional AHP method, the clustering analysis is taken on traditional grade data based on expert scoring method, the maximum difference grade is eliminated by using clustering theory with weighted Euclidean distance, and the weighing of evaluation index is achieved by comprehensively using AHP method and weighted average integrated function, all of these could increase reliability and veracity of evaluation result and enhance the influence effect of importance evaluation index on evaluation result. In the end, the rationality and reliability of the method is validated by examples.
