The Ranking Systems Research (RSR) Group is supported by the National Research, Development and Innovation Office under Grant FK 145838.
A paper co-authored by two members of the research group entitled An experimental approach: Converting verbal expressions to numerical scales appeared in Operations Research Perspectives on 1 September 2026.
A paper authored by two members of the research group entitled Refined thresholds for inconsistency: The effect of the graph associated with incomplete pairwise comparisons appeared in Expert Systems with Applications on 19 May 2026.
We have organised the 4th Fairness in Sports workshop on 12 June 2026 at Corvinus University of Budapest, Hungary.
Ranking is a fundamental issue in many fields of science: rankings are used to represent both individual and collective preferences, allocate financial and other resources, or support potentially life-changing decisions.
We are focusing on two specific fields where rankings play a prominent role: pairwise comparison matrices and sports tournaments.
The goal of the project is to demonstrate that the axiomatic analysis of ranking systems can offer new and important insight into both decision-making methods and sports rules.
