【Abstract】 Reduction and core are two important concepts and significantly applied in rough set. Several natures and theorems of Skowron’s discernable matrix are gained by utilizing the reduction and core concepts. And by utilizing the results above, some methods of researching core finding and relative reduction about inconsistent information decision table are proposed, and the examples of their application demonstrate the effectiveness of the methods.更多还原
