摘要
在双枝模糊集和粗集的基础上,提出了双枝模糊粗集的截集的概念;利用双枝模糊粗集的截集,讨论了下枝模糊粗集、上枝模糊粗集及双枝模糊粗集的结构,给出了双枝模糊粗集的分解定理.
On the basis of both-branch fuzzy sets and rough sets,the concept of cut sets of both-branch fuzzy rough sets was posed. By using cut sets of both-branch fuzzy rough sets,the structure of lower branch fuzzy rough sets,upper branch fuzzy rough sets and both-branch fuzzy rough sets were discussed. The decom-position theorem of both-branch fuzzy rough sets was given.
