| 摘 要： | 将粗糙集与区间值模糊集相结合便可得到区间值粗糙模糊集.通过将经典粗糙集模型中论域上的等价关系用论域的覆盖来替换,建立了基于覆盖关系的区间值粗糙模糊集模型,并给出了该模型下的一些基本性质.

| Abstract: | By integrating the classical Pawlak rough sets with the interval-valued fuzzy sets, the intervalvalued rough-fuzzy sets model is made up. By replacing equivalent relation on universe with its cover, the interval-valued rough-fuzzy sets model based on covering is builded, meanwhile, some corresponding properties are given. |
