An experimental approach: Converting verbal expressions to numerical scales
Zsombor Szádoczki, Sándor Bozóki, László Sipos +1
One of the key issues in decision problems is the selection and use of the appropriate response scale. In this paper verbal expressions are converted into numerical scales for a su…
Increasing competitiveness by imbalanced groups: The example of the 48-team FIFA World Cup
László Csató, András Gyimesi
A match played in a sports tournament can be called stakeless if at least one team is indifferent to its outcome because it already has qualified or has been eliminated. Such a gam…
A clustering approach for pairwise comparison matrices
Kolos Csaba Ágoston, Sándor Bozóki, László Csató
We consider clustering in group decision making where the opinions are given by pairwise comparison matrices. In particular, the k-medoids model is suggested to classify the matric…
How to choose a completion method for pairwise comparison matrices with missing entries: An axiomatic result
László Csató
Since there exist several completion methods to estimate the missing entries of pairwise comparison matrices, practitioners face a difficult task in choosing the best technique. Ou…
Right-left asymmetry of the eigenvector method: A simulation study
László Csató
The eigenvalue method, suggested by the developer of the extensively used Analytic Hierarchy Process methodology, exhibits right-left asymmetry: the priorities derived from the rig…
On the coincidence of optimal completions for small pairwise comparison matrices with missing entries
László Csató, Kolos Csaba Ágoston, Sándor Bozóki
Incomplete pairwise comparison matrices contain some missing judgements. A natural approach to estimate these values is provided by minimising a reasonable measure of inconsistency…
The incomplete Analytic Hierarchy Process and Bradley-Terry model: (in)consistency and information retrieval
László Gyarmati, Éva Orbán-Mihálykó, Csaba Mihálykó +2
Several methods of preference modeling, ranking, voting and multi-criteria decision making include pairwise comparisons. It is usually simpler to compare two objects at a time, fur…
A lexicographically optimal completion for pairwise comparison matrices with missing entries
Kolos Csaba Ágoston, László Csató
Estimating missing judgements is a key component in many multi-criteria decision making techniques, especially in the Analytic Hierarchy Process. Inspired by the Koczkodaj inconsis…
Optimal sequences for pairwise comparisons: the graph of graphs approach
Zsombor Szádoczki, Sándor Bozóki
In preference modelling, it is essential to determine the number of questions and their arrangements to ask from the decision maker. We focus on incomplete pairwise comparison matr…
Tournament schedules and incentives in a double round-robin tournament with four teams
László Csató, Roland Molontay, József Pintér
In a round-robin tournament, a team may lack the incentive to win if its final rank does not depend on the outcome of the matches still to be played. This paper introduces a classi…
IP Solutions for International Kidney Exchange Programmes
Péter Biró, Márton Gyetvai, Radu Stefan Mincu +2
In kidney exchange programmes patients with end-stage renal failure may exchange their willing, but incompatible living donors among each other. National kidney exchange programmes…
Incomplete Analytic Hierarchy Process with Minimum Weighted Ordinal Violations
Luca Faramondi, Gabriele Oliva, Sándor Bozóki
Incomplete pairwise comparison matrices offer a natural way of expressing preferences in decision making processes. Although ordinal information is crucial, there is a bias in the…
On the monotonicity of the eigenvector method
László Csató, Dóra Gréta Petróczy
Pairwise comparisons are used in a wide variety of decision situations where the importance of alternatives should be measured on a numerical scale. One popular method to derive th…
Characterization of the row geometric mean ranking with a group consensus axiom
László Csató
An axiomatic approach is applied to the problem of extracting a ranking of the alternatives from a pairwise comparison ratio matrix. The ordering induced by row geometric mean meth…
A characterization of the Logarithmic Least Squares Method
László Csató
We provide an axiomatic characterization of the Logarithmic Least Squares Method (sometimes called row geometric mean), used for deriving a preference vector from a pairwise compar…
The (logarithmic) least squares optimality of the arithmetic (geometric) mean of weight vectors calculated from all spanning trees for incomplete additive (multiplicative) pairwise comparison matrices
Sándor Bozóki, Vitaliy Tsyganok
Complete and incomplete additive/multiplicative pairwise comparison matrices are applied in preference modelling, multi-attribute decision making and ranking. The equivalence of tw…
Efficiency analysis of double perturbed pairwise comparison matrices
Kristóf Ábele-Nagy, Sándor Bozóki, Örs Rebák
Efficiency is a core concept of multi-objective optimization problems and multi-attribute decision making. In the case of pairwise comparison matrices a weight vector is called eff…
Efficient weight vectors from pairwise comparison matrices
Sándor Bozóki, János Fülöp
Pairwise comparison matrices are frequently applied in multi-criteria decision making. A weight vector is called efficient if no other weight vector is at least as good in approxim…
Multiple summation inequalities and their application to stability analysis of discrete-time delay systems
Eva Gyurkovics, Krisztina Kiss, Ilona Nagy +1
This paper is devoted to stability analysis of discrete-time delay systems based on a set of Lyapunov-Krasovskii functionals. New multiple summation inequalities are derived that i…
Incomplete pairwise comparison matrices and weighting methods
László Csató, Lajos Rónyai
A special class of preferences, given by a directed acyclic graph, is considered. They are represented by incomplete pairwise comparison matrices as only partial information is ava…
Efficiency analysis of simple perturbed pairwise comparison matrices
Kristóf Ábele-Nagy, Sándor Bozóki
Efficiency, the basic concept of multi-objective optimization is investigated for the class of pairwise comparison matrices. A weight vector is called efficient if no alternative w…
On reducing inconsistency of pairwise comparison matrices below an acceptance threshold
Sándor Bozóki, János Fülöp, Attila Poesz
A recent work of the authors on the analysis of pairwise comparison matrices that can be made consistent by the modification of a few elements is continued and extended. Inconsiste…
