| Abstract: | The association of information entropy and knowledge significance with knowledge redundancy in an uncertain system is set up in this paper due to the decision dependence on condition attributes. It is concluded that proach to analyzing knowledge redundancy and knowledge simplification of an uncertain system is presented on information entropy. The theoretical analysis and the p method are validated by some examples. |
