| Abstract: | RV set (Rough-Vague set) is introduced by combining Rough set and Vague set. Some essential properties of RV set are discussed. And fuzzy entropy, rough-degree and close-degree of RV set are defined based on rough entropy of Rough set and fuzzy entropy of Fuzzy set which are used describing the uncertainty. In addition, fuzzy entropy, rough-degree and close-degree of RV set are discussed, also relevant theorems are presented |
