Binary relationship set
WebFurther, a composite binary relation that fits the realistic attribute features is constructed. Subsequently, considering different decision scenarios, we establish four kinds of variable precision multi-decision multi-granulation rough set models. Meanwhile, the related properties and relationships of these models are explored. WebDe nition: Let R be a binary relation on a set X. A real-valued function u : X !R is a utility function for R, or a representation of R, if 8x;x0 2X : u(x0) =u(x) ,x0Rx: R is said to be …
