Efficient tensor bases for pairwise comparisons
Konrad Kułakowski, Ryszard Smarzewski
In this study, we construct the first orthogonal basis for additively consistent subspace in pairwise comparisons theory. This construction is based on our representation of additi…
Geometric mean-based pairwise comparison method with the reference values -- statistical approach
Konrad Kułakowski, Kamil Pustelnik, Jacek Szybowski
For many years, pairwise comparison methods have been widely used for eliciting preferences and ranking alternatives in decision-making problems. These methods estimate priority we…
Sufficient conditions for a Heuristic Rating Estimation Method application
Jacek Szybowski, Konrad Kułakowski, Jiri Mazurek
A series of papers has introduced the Heuristic Rating Estimation method, which evaluates a set of alternatives based on pairwise comparisons and the weights of reference alternati…
My part is bigger than yours -- assessment within a group of peers
Konrad Kułakowski, Jacek Szybowski
A project (e.g., writing a collaborative research paper) is often a group effort. At the end, each contributor identifies their contribution, often verbally. The reward, however, i…
Detection of decision-making manipulation in the pairwise comparisons method
Michał Strada, Sebastian Ernst, Jacek Szybowski +1
Most decision-making models, including the pairwise comparison method, assume the decision-makers honesty. However, it is easy to imagine a situation where a decision-maker tries t…
