A New Model of Rough-Fuzzy Sets

Fuzzy-rough sets of existing mode are too abstract to the practical problems. It is not of much practical significance. But, the rough-fuzzy sets of existing mode for dynamic data processing capability are poor. This paper proposes new rough-fuzzy sets, which have integrated the advantages of the rough sets and fuzzy sets of data processing better, and have more practical significance for the settlement of the problems. The cut sets of data can be better in the equivalent class of analysis in the decision-making.
