| Abstract: | A method of rule generation based on Rough set is presented.The method creates the core and a series of the reduction sets from discernibility matrix and discernibility function of the known decision system.With the reduction sets as first nodes,the nodes network model of different reductive levels is developed.Its own rule sets with suitable confidence is reasoned at each node.By an example the correctness of the method is verified. |
