Abstract Based on an intuitionistic fuzzy relation, we propose set model on two universes. Meanwhile, the concepts of the inverse lower and upper approximation operators are presented. We also study some properties of these approximation operators, from which we obtain new theory and practical approach to apply rough sets. Finally, an illustrative example in the clinical diagnose system is applied to show the validity and superiority of the proposed intuitionistic fuzzy probabilistic rough set model.
