Abstract:

The concepts of the precision degree and rough degree of function two-direction S-rough sets are given, which is based on [WTHT]P[WTBZ]?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.

Key words: function twodirection Srough sets; P-rough integrals; rough degree
