摘要
在函数双向S-粗集生成的P-粗积分的基础上提出了函数双向S-粗集的精度与粗糙度的概念,讨论了函数双向S-粗集的精度与粗糙度的一系列特性,并得到函数双向S-粗集的可分辨准则与函数双向S-粗集的筛选-剩余定理。
The concepts of the precision degree and rough degree of function two-direction S-rough sets are given,which is based on P-rough integrals generated by function two-direction S-rough sets.And a series of their characteristics are discussed.Also,the discernible criterion of function two-direction S-rough sets and the screening-surplus theorem of it are obtained.
