Tolerance-based multigranulation rough sets in incomplete system...

<span> </span> <p> <span><span>Presently, the notion ofmultigranulation has been brought to our attention. In this paper, the multigranulation technique is introduced into incomplete information systems. Both tolerance relations and maximal consistent blocks are used to construct multigranulation rough sets. Not only are the basic properties about these models studied, but also the relationships between different multigranulation rough sets are explored. It is sho
