Covering-Based Optimistic-Pessimistic Multigranulation Decision-Theoretic Rough Sets
Multigranulation decision-theoretic rough sets (MDTRS) is a workable model for real-world decision making. The fruitful research achievements of the use of these models have been reported in different aspects....

Covering-Based Optimistic Multigranulation Decision-Theoretic Rough Sets Based on Maximal Descriptors
This paper investigates decision-theoretic rough set approach in the frameworks of multi-covering approximation space. We mainly discuss optimistic multigranulation decision-theoretic rough sets by employing m...

Optimistic Decision-Theoretic Rough Sets in Multi-covering Space
This paper discusses optimistic multigranulation decision-theoretic rough sets in multi-covering space. First, by using the strategy “seeking commonality while preserving difference”, we propose the notion of ...

A New Subsystem-Based Definition of Generalized Rough Set Model
The generalization of Pawlak rough set model always attracts the attentions of the researchers in the rough set society. In this paper, we propose a new subsystem-based definition of generalized rough set mode...

Multi-granulation Rough Sets Based on Central Sets
Exploring rough sets from the viewpoint of multi-granulation has become one of the promising topics in rough set theory, in which lower or upper approximations are approximated by multiple binary relations. Th...
