Abstract :
The main purpose of this paper is to present a general framework for the study of fuzzy rough approximation operators based on pseudo-operations. In this paper, using the pseudo-operation, the pseudo-generalized fuzzy rough sets are presented and some properties of the pseudo fuzzy rough approximation operators are investigated. Meanwhile, connections between the proposed pseudo fuzzy rough approximation operators and the existing fuzzy rough approximation operators are also discussed.
