This paper concerns the relationship between rough sets, -fuzzy sets, and the LA-semihypergroups. We proved that the lower approximation (-approx) and the upper approximation (-approx) of different hyperideals of LA-semihypergroups become again hyperideal and also provided some examples. We also provided a result which shows that, if is not a hyperideal of an LA-semihypergroup , then its lower approximation is also not a hyperideal.

有序LA半超群中-Fuzzy超理想的近似

本文涉及粗糙集之间的关系， -模糊集和LA半超群。我们证明了LA半超群的不同超理想的低近似（ -近似）和高近似（ -近似）再次变为超理想，并提供了一些例子。我们还提供了一个结果，该结果表明，如果不是LA半超群的超理想主义，那么其较低的近似值也不是超理想主义。
