Abstract :
This paper is to explore new improved graded rough set model. Based on logical OR operation of grade approximation operators, this paper proposes logical OR model of grade approximation operators. In the new model, basic structure and properties are obtained, and macroscopic algorithm and structural algorithm are proposed. Finally logical OR model of grade approximation operators, is explained by a medical example.
