| Abstract: | The paper introduces the concept of dynamic fuzzy approximation in Dubois fuzzy rough set based on the theory of Z.Pawlak rough set. Based on this, the concept of two-direction S-rough set is proposed, and its general structure and basic properties are given. The relationship between a two-direction S-fuzzy rough set and Z.Pawlak rough set, Dubois fuzzy rough set, S-rough set and S-rough fuzzy set, between a two-direction S-fuzzy rough set and a one-direction S-fuzzy rough set are analyzed. The application and existing value of two-direction S-fuzzy rough set is given. |
