Recent advances on inconsistency indices for pairwise comparisons - a commentary
This is an incremental commentary paper for researchers in decision theory and pairwise comparisons.
This paper reviews consistency definitions and inconsistency indices for pairwise comparison matrices, commenting on a recent contribution to show that debates on inconsistency indices remain active.
This paper recalls the definition of consistency for pairwise comparison matrices and briefly presents the concept of inconsistency index in connection to other aspects of the theory of pairwise comparisons. By commenting on a recent contribution by Koczkodaj and Szwarc, it will be shown that the discussion on inconsistency indices is far from being over, and the ground is still fertile for debates.
