Abstract

According to the advantages of multi-granularity rough set and possible degree tolerance relation, this paper proposed a rough set based on possible degree tolerance relationship. Firstly, it came up with possible degree and defined a novel possible degree tolerance relation. Then, based on possible degree tolerance relation, it construted the optimistic and pessimistic multi-granulation decision rough set model. It gave the upper lower approximations of the model and proved the relevant theorems and properties. Finally, by use of a case, it verified that the new method had feasibility and effectiveness. The experimental results show that the proposed model has a fault tolerance and strong classification ability by adjusting the parameter ω.
