基于18元语言值格蕴涵代数,提出了语言值模糊集的语言值模糊相似度概念,给出平均语言值模糊相似度计算公式,并证明了其合理性;然后构建了语言值模糊相似矩阵、语言值模糊等价矩阵及语言值模糊矩阵的λ-截矩阵;最后提出了一种基于语言值模糊相似矩阵的聚类新方法,并给出了实例验证。
Based on the 18-element linguistic-valued lattice implication algebra, the linguistic-valued fuzzy similarity of linguistic-valued fuzzy set was proposed. In addition, the calculating formular for average linguistic-valued fuzzy simi- larity was given and its reasonability was proved. Furthermore, the linguistic-valued fuzzy similar matrix, linguistic- valued fuzzy equivalent matrix and A-cut matrix of linguistic-valued fuzzy matrix were constructed. Finally, a new fuzzy clustering method based on linguistic-valued fuzzy similar matrix was proposed, and an example was given to il- lustrate its effectivity in fuzzy clustering problem.
