相似度与包含度是度量模糊集的两个重要指标。介绍在有限论域上直觉模糊集的相似度与包含度的定义,重点研究σ-相似度和σ-包含度的性质,分别给出σ-相似度和σ-包含度的一些等价条件,进而给出σ-相似度与σ-包含度之间的相互诱导关系。
Similarity and inclusion degree are two important indicators of fuzzy set. This paper introduces the definition of similarity and inclusion degree of intuitionistic fuzzy sets on finite domains, focuses on the properties of σ-degree of similarity and σ-degree of inclusion, gives some equivalent conditions of σ-degree of similarity and σ-degree of inclusion, Furthermore, we give the mutual inducement between σ-degree of similarity and σ-degree of inclusion.
