Abstract

Ordinal consistency is the prerequisite of a fuzzy judgment matrix. Based on the transitivity of its superior relation, two concepts of non-transitive route number and non-transitive route contribution number were put forward. Through the non-transitive route number and non-transitive route contribution number guidance, a revising method for fuzzy judgment matrix without ordinal consistency was proposed, in which the irrational element can be identified. The revising method can help the decision-maker revise his/her judgment matrix effectively.
