摘要
将基于逻辑算子的粗糙模糊集推广到格L上,定义基于逻辑算子的广义L-模糊粗糙集,和一对广义L-模糊粗糙算子,最后研究其性质并给出了证明.
This paper generalizes the fuzzy rough approximation to the lattice L and gives the generalized L -fuzzy rough approximation based on the residuation implicationOas well. A pair of lower and upper generalized approximation operators is defined and their properties are investigated.
