摘　　要：将粗糙集理论和Vague集理论相结合,引入了粗糙Vague集的概念,讨论了粗糙Vague集的基本性质.并且基于描述模糊信息量的模糊熵及描述粗糙集的粗糙熵,给出了粗糙Vague集的模糊熵、粗糙度及贴近度的定义,讨论了粗糙Vague集的模糊熵、粗糙度及贴近度,并给出了相应的定理。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 oresented
