Abstract :
In this paper we select TL-fuzzy rough sets to analysis error estimation of perturbations since it is more suitable for practical problems than other kind of fuzzy rough sets. We first adopt the continuity of lower and upper approximation operators in the TL-fuzzy rough sets, we then estimate errors of the approximations of a fuzzy set affected by perturbations of inputs in approximation operators of TL-fuzzy rough sets.
