Characterizations of consistent pairwise comparison matrices over abelian linearly ordered groups
Bice Cavallo, Livia D’Apuzzo · International Journal of Intelligent Systems · 2010
We consider the framework of pairwise comparison matrices over abelian linearly ordered groups. We introduce the notion of ⊙-proportionality that allows us to provide new characterizations of the consistency, efficient algorithms for checking the consistency and for building a consistent matrix. Moreover, we provide a new consistency index. © 2010 Wiley Periodicals, Inc.
