摘要
196 5年 ,Zadeh提出了 Fuzzy集理论 ,1982年 ,Z.Pawlak提出 Rough集理论。将二者结合而形成的模糊粗糙集 (FR集 )及粗糙模糊集 (RF集 )近年来越来越受到国际学术界的关注。本文所研究的 FR集及 RF集的模糊度 ,是对 FR集及 RF集模糊程度的一种度量。进而引进了相应的明可夫斯基距离 ,明可夫斯基模糊度和
The concept of fuzzy sets was introduced by Zadeh in 1965 and subsequently the notion of rough sets was introduced by Pawlak in 1982,the combination of them formed fuzzy rough sets and rough fuzzy sets, which have been followed with much attention by international academic circles. The paper discusses the fuzzy degree of fuzzy rough sets and rough fuzzy sets, which is a measure of fuzzy level.
