Multiple-criteria Heuristic Rating Estimation
Anna Kędzior, Konrad Kułakowski
One of the most widespread multi-criteria decision-making methods is the Analytic Hierarchy Process (AHP). AHP successfully combines the pairwise comparisons method and the hierarc…
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 geometric mean method for incomplete pairwise comparisons
Konrad Kułakowski
When creating the ranking based on the pairwise comparisons very often, we face difficulties in completing all the results of direct comparisons. In this case, the solution is to u…
Inconsistency indices for incomplete pairwise comparisons matrices
Konrad Kułakowski, Dawid Talaga
Comparing alternatives in pairs is a very well known technique of ranking creation. The answer to how reliable and trustworthy ranking is depends on the inconsistency of the data f…
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…
When is the condition of order preservation met?
Konrad Kulakowski, Jiri Mazurek, Jaroslav Ramik +1
This article explores a relationship between inconsistency in the pairwise comparisons method and conditions of order preservation. A pairwise comparisons matrix with elements from…
