Recent advances on inconsistency indices for pairwise comparisons - a commentary

TL;DR

This paper reviews the concept of inconsistency indices in pairwise comparison matrices, discusses recent debates, and highlights ongoing research challenges in the field.

Contribution

It provides a commentary on recent work by Koczkodaj and Szwarc, emphasizing unresolved issues and future research directions in inconsistency indices.

Findings

Inconsistency indices are crucial for evaluating pairwise comparison matrices.

The discussion on inconsistency indices remains active and unresolved.

Abstract

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.
