| 摘 要： | 当知识库中的知识模块既是模糊的又是随机得到的，我们定义了基于随机模糊集的粗糙集模型。给出了随机模糊粗糙集的性质。讨论了利用模糊集的下近似和上近似定义的模糊测度和概率模糊测度的关系。

| Abstract: | As knowledge block in knowledge base is fuzzy and is obtained randomly, we study the rough set model based on random fuzzy rough sets. We give some properties of random fuzzy rough sets. We discuss the relation between fuzzy measure defined by lower approximation and upper approximation of fuzzy set and probability fuzzy measures. |

| Keywords: | random fuzzy set approximation space random fuzzy rough set probability fuzzy measure |
