| 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，并形成了具有分类功能的模糊等价矩阵。按照不同的置信度水平，对构件的耐久性进行动态聚类。通过算例的分析比较，证明该方法是合理的，并且避免了按照传统方法进行评估的不合理性，易于通过编程实现。

| Abstract: | Based on the dynamic cluster analysis of fuzzy equivalence relation,an evaluation method of durability of components is proposed.The method measures the similarity of durability index series of components by the use of similarity coefficient and forms a fuzzy equivalence matrix with sort function.Then components are dynamically clustered according to different degrees of confidence.The method proves to be correct.It avoids the irrationality in the conventional method and can be easily realized by programming. |
