Abstract: The consistency of judgement matrix is vital for decision in AHP But it is hard to keep the consistency of judgement matrix because they used to be determined by experts In this paper,the dependency factor,a concept in rough set is proposed to construct judgement matrix of AHP The method need not compare factors directly But it utilizes fully the information in schemes and experts’subjective judgment

Key words: Variable precision rough set, consistency, AHP
