Abstract: The attribute significance degree concept is improved in this paper, it proposes an improved method of attribute weight assignment of signal and attribute significance degree based on rough set. A case is used to prove that improved weighting method is more to fit practice and make weight more reasonable than before.

Key words: rough sets, attribute significance degree, weight
