Abstract :
Aimed at the ordering problem of fuzzy sets, an approximate fuzzy set is obtained by rough fuzzy sets. It has good geometric meaning and simple operation, which makes it a good approximation method to research fuzzy sets. Since rough fuzzy number keeping weak partial order, by this property, better research results are gained on ordering of fuzzy sets. This method has universal significance and be worth promoting. An example is used to verify the method proposed in this paper.
