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 Voting power in the Council of the European Union: A comprehensive sensitivity analysis appeared in Group Decision and Negotiation on 27 January 2026.
An interview with the leader of the research group, László Csató, appeared in the Hungarian radio program Trend-idők on 31 December 2025 (in Hungarian).
We will organise 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.
