Abstract

As a further exploration of the multi-attribute covering decision information system from more diverse angles, this paper proposed a weighted multi-granularity rough set based on induced covering relation. Firstly, it analyzed the limitation of granular weight's determination depend on expert experience. In order to obtain relatively objective decision results, it adopted the granular weight assignment method based on classification accuracy. Then, it introduced the induced covering relation into the weighted multi-granulation rough set, and acquired the complete upper and lower approximations of the rough set. Further, it discussed the relationship between metric parameters and proved the related properties and theorems. Finally, the experimental results verify the validity and practicability of the model.
