| 摘 要： | 构造了一组新的广义模糊粗糙近似算子,将其拓展到区间上.在由任意的二元区间值模糊关系构成的广义近似空间中,证明了该组近似算子与区间化的广义Dubois模糊粗糙近似算子是等价的,最后在一般二元区间值模糊关系下对该组近似算子的性质进行了讨论. |
| 关 键 词： | 近似算子 广义模糊粗糙集 区间值模糊关系 |

| Abstract: | New lower and upper approximation operators of generalized fuzzy rough sets were constructed and extended their definition to interval.These operators were proved to be equivalent to generalized interval dubois fuzzy rough app-roximation operators in a generalized approximation space formed by any interval-valued fuzzy binary relations.Typical properties of these operators were discussed based on generalized interval-valued fuzzy binary relation. |
| Keywords: | Approximation operators Generalized fuzzy rough sets Interval-valued fuzzy relations |
