多粒度广义L-模糊可变精度粗糙集
Multi-granulation Generalized L-fuzzy Variable Precision Rough Set
摘要
Abstract
In order to deal with the imprecise problem effectively, the combination of the fuzzy variable precision rough set with multi-granulation has become a research hotspot. Based on the non-commutative generalized residual lattice, the left lower ( right lower) and left upper ( right upper) approximation oper-ators of generalized L-fuzzy variable precision rough set were defined in the L-fuzzy approximation space. Then, combing with multi-granulation, multi-granulation generalized L-fuzzy variable precision rough set and approximation operators were defined, and their properties were explored. The findings of this study explored the research of variable precision rough set, and provided a new method to solve the imprecise problem in practice.关键词
