Abstract :
In this paper, we propose a fuzzy relation, called the grade indiscernibility relation, for incomplete information system to characterize the similarity between objects. The rough set model based on the grade indiscernibility relation is presented with its basic properties being discussed. Furthermore, decision rules acquisitions based on the grade indiscernibility relation are analyzed.
