Abstract:

Function one direction S-rough sets (function one direction singular rough sets) was defined by the R-function equivalent class ［u］, which has dynamic characteristic, and the function one direction S-rough sets has law (function) characteristic. By using function one direction S-rough sets, the  concepts of the structure of F-rough law (w-(x)F,w-(x)F), the attribute characteristic of rough law (w-(x),w-(x)), attribute distance, and status coefficient were presented, and F-rough law and its attribute control, the principle of attribute control, attribute control theorem and applications were proposed. F-rough law and its attribute control is a new application research direction of function S-rough sets (function singular rough sets).

Key words: function one direction Srough sets; rough law; attribute characteristic; attribute control; attributer control theorem
