Abstract

In this paper, we propose a method that can improve a multiplicative inconsistency by revising the potential inconsistent elements of an intuitionistic fuzzy preference relation (IFPR) without constructing a multiplicative consistent IFPR. After converting the given IFPR into a positive reciprocal matrix based on multiplicative consistency, the necessary and sufficient conditions for the IFPR to be multiplicative consistent or inconsistent put forward. A symmetric deviation matrix that can take accurate measurement of consistency bias of every element in an IFPR is constructed. Which of elements in the IFPR corresponding to the largest bias in the deviation matrix are really inconsistent, is verified by a bias verifying vector and a new method of eliminating alternatives, and are uniquely determined by using the fact that all the determinacy degrees of the IFPR remain constant in the revising process. The proposed method can preserve most information of the original IFPR as well as need a few operations in comparison with previous methods because they require to calculate underlying priority weights of alternatives based on a model. Meanwhile an associated example is offered to show the correctness and efficiency of the proposed method.
