| Abstract: | By employing function one-direction S-rough sets, the generation method 〖JP2〗and correlative concepts of f-model and f-t order one-direction dynamic model of R-function equivalence class ［u(x)］, and the generation method and the correlative concepts of F-model and F-one-direction dynamic model were proposed. Then the order relation theorem and the dynamic separation theorem of F-one direction dynamic model were presented. The dynamic characteristic of F-model depends on the attribute augment to the attribute set α. The generation principle of F-model and its application were given on the basis of the above research. |
