Fuzzy rough set based on lattice effect algebra
Xiujuan Hua · Journal of Intelligent & Fuzzy Systems · 2018
In this paper, L -fuzzy rough sets as a further generalization of the notion of fuzzy rough sets are proposed. Moreover, some properties in lattice ordered effect algebra are presented. A group of approximation operators are defined by the new operation in effect algebra, which is introduced by Zhou X.N., Li Q.G. and Wang G.J. And some equivalent statements in an L -fuzzy approximation space are investigated. Finally, the notion of generalized L -fuzzy relational morphism of lattice effect algebra is introduced and the fundamental properties of it are studied.
