Abstract: This paper proposed two kinds of covering-based multigranulation rough sets by employing the maximal description of elements.Firstly,some basic properties of the models were investigated.Then,the conditions for two distinct covering-based multigranulation rough sets to produce the identical lower and upper approximations were studied.Finally,the relationships between the two models were explored.

Key words: Rough sets,Multigranulation,Covering,Reduct,Maximal description
