报告摘要:In this paper, we investigate the multiplicative consistency of fuzzy reci-procal preference relations. Firstly, we propose an inconsistency identification and m-odification (IM) method, which is based on the multiplicative consistency property and allows us to improve the consistency of fuzzy reciprocal preference relations. When a fuzzy reciprocal preference relation is incomplete, we apply the IM method by introd-ucing and solving a constrained nonlinear optimization model to estimate the missing values. Therefore, the proposed IM method can be used to deal with the inconsistency problem for both complete fuzzy reciprocal preference relations and incomplete ones. Finally, some numerical examples are illustrated. In addition, a discussion and a comp-arison with other similar methods are provided to show the correctness, effectiveness, and robustness of the proposed methods. Compared with the existing methods, our me-thods not only need less iterations, but also achieve better consistency meanwhile pres-erving the original preference information as much as possible.
