On Orthogonal Projections on the Space of Consistent Pairwise Comparisons Matrices

W. W. Koczkodaj, R. Smarzewski, J. Szybowski

In this study, the orthogonalization process for different inner products is applied to pairwise comparisons. Properties of consistent approximations of a given inconsistent pairwi…

New inconsistency indicators for incomplete pairwise comparisons matrices

Jacek Szybowski, Konrad Kułakowski, Anna Prusak

We introduce two new inconsistency measures for the incomplete pairwise comparisons matrices and show several examples of their calculation. We also carry out a comparative analysi…

On the use of group theory to generalize elements of pairwise comparisons matrix: a cautionary note

W. W. Koczkodaj, F. Liu, V. W. Marek +11

This paper examines the constricted use of group theory in the studies of pairwise comparisons. The presented approach is based on the application of the famous Levi Theorems of 19…

Towards quantification of incompleteness in the pairwise comparisons method

Konrad Kułakowski, Anna Prusak, Jacek Szybowski

Alongside consistency, completeness of information is one of the key factors influencing data quality. The objective of this paper is to define ways of treating missing entries in…

On normalization of inconsistency indicators in pairwise comparisons

W. W. Koczkodaj, J. -P. Magnot, J. Mazurek +6

In this study, we provide mathematical and practice-driven justification for using normalization of inconsistency indicators in pairwise comparisons. The need for normaliza…

On the Convergence of the Pairwise Comparisons Inconsistency Reduction Process

Waldemar W. Koczkodaj, Jacek Szybowski

This study investigates a powerful model, targeted to subjective assessments, based on pairwise comparisons. It provides a proof that a distance-based inconsistency reduction trans…
