Abstract：In this paper, the concept of variable precision T-rough sets is given, and some properties of it are studied.The changes about parameter of double parametes variable precision T-rough sets are investigated.The theoretical system of rough set has been enriched by the results obtained in this paper from operator theory and set theory point of views.
