The Dual of Function One direction Singular Rough Sets and FRough Marginal Laws |
| |
| Abstract: | The dual of function one direction singular rough sets is one type of forms about function singular rough sets.It has dynamic specific property and law characteristics.The function singular rough sets came from improved S-rough sets by introducing function concept to S-rough sets..By intersecting and infiltrating between derivative and dual of function one direction singular rough sets,rough marginal laws and F-rough marginal laws are given;and characteristics of rough marginal laws and F-rough marginal laws are obtained;and the relations betweenF-rough marginal laws and rough marginal laws are proposed.Finally,the paper puts forward the application of the in the F-rough marginal laws in the economic information system. |
