A New Method of Adjusting Inconsistent Pairwise Comparison Matrix

摘要

In this paper, we develop a new approach to adjust an inconsistent pairwise comparison matrix (PCM). By deriving the consistent matrices from given PCM and finding out maximum consistent set of PCM, the consistent benchmark matrix of given PCM is obtained. Then, we can adjust the inconsistency by linear combination of the original PCM and benchmark matrix. Considering the reality of new PCM, a possible threshold of the value of linear combination parameter is given a mention. Finally, an illustrative example is given to show the practicality of the method.
