摘　　要：在粗糙集和双枝模糊集的基础上,给出了粗双枝模糊集的概念;讨论了粗下枝模糊集,粗上枝模糊集和粗双枝模糊集的性质;利用模糊集的λ-截集及λ-强截集,讨论了粗双枝模糊集的数学结构及表示.On the basis of rough sets and both branch fuzzy sets, the paper explicates the concept of rough both branch fuzzy sets. The characteristics of rough down branch fuzzy sets, rough up branch fuzzy sels and rough both -branch fuzzy sets are discussed; Depending on the introduction of λ cut sets and λ-strong cut sets, the mathematics structure and characterizations of rough both-branch fuzzy sets are discussed.
