摘要
本文提出了区间值fuzzy集的上(下)-fuzzy集及[λ_1,λ_2]-截集,并讨论了它们的基本性质.
The concepts of upper (lower)-fuzzy sets and [λ_1, λ_2]-cutsets for interval valued fuzzy sets are presented, and their basic properties are discussed. Based on this, a number of decomposition and expression theorems for interval-valued fuzzy sets are established.
