摘　　要：基于模糊等价关系的动态聚类分析,提出了一种构件耐久性评估方法.该方法先利用相似系数在各构件的耐久性指标序列之间进行相似性度量,得到具有分类功能的模糊等价矩阵;然后按照不同的置信度水平,对构件耐久性进行动态聚类.算例分析比较结果表明,该方法不仅可避免按传统方法进行评估的不合理性,而且易于编程实现.Based on the dynamic cluster analysis of fuzzy equivalence relation, a durability evaluation method for components was proposed. In this method, the similarity coefficient was used for similarity measurement in durability index series of different components, and a fuzzy equivalence matrix with sort function was obtained. Then the dynamic cluster of the durability of components was performed according to different degrees of confidence. An example was given to show that the present method could avoid the irrationality of the conventional method and could be easily realized by programming.
