Towards secure judgments aggregation in AHP
Konrad Kułakowski, Jacek Szybowski, Jiri Mazurek +1
In decision-making methods, it is common to assume that the experts are honest and professional. However, this is not the case when one or more experts in the group decision making…
On the Derivation of Weights from Incomplete Pairwise Comparisons Matrices via Spanning Trees with Crisp and Fuzzy Confidence Levels
Jiri Mazurek, Konrad Kułakowski
In this paper, we propose a new method for the derivation of a priority vector from an incomplete pairwise comparisons (PC) matrix. We assume that each entry of a PC matrix provide…
A gradient method for inconsistency reduction of pairwise comparisons matrices
Jean-Pierre Magnot, Jiří Mazurek, Viera Čerňanová
We investigate an application of a mathematically robust minimization method -- the gradient method -- to the consistencization problem of a pairwise comparisons (PC) matrix. Our a…
On the similarity between ranking vectors in the pairwise comparison method
Konrad Kułakowski, Jiří Mazurek, Michał Strada
There are many priority deriving methods for pairwise comparison matrices. It is known that when these matrices are consistent all these methods result in the same priority vector.…
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…
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…
Which Football Player Bears Most Resemblance to Messi? A Statistical Analysis
Jiri Mazurek
Many pundits and fans ask themselves the same question: Which football player bears most resemblance to Lionel Messi? Is it Chelsea's Eden Hazard? Is it Paulo Dybala, the heir to M…
On Inconsistency Indices and Inconsistency Axioms in Pairwise Comparisons
Jiri Mazurek
Pairwise comparisons are an important tool of modern (multiple criteria) decision making. Since human judgments are often inconsistent, many studies focused on the ways how to expr…
A modification to Hirsch index allowing comparisons across different scientific fields
Jiri Mazurek
The aim of this paper is to propose a simple modification to the original measure, the relative Hirsch index, which assigns each researcher a value between 0 (the bottom) and 1 (th…
Fuzzy Rankings: Properties and Applications
Jiří Mazurek
In practice, a ranking of objects with respect to given set of criteria is of considerable importance. However, due to lack of knowledge, information of time pressure, decision mak…
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…
