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.
