This study compares the competitive balance (CB) of these new tournament formats with the previous Champions League format. Short-, mid- and long-term CB are quantified by measuring the average uncertainty of match outcomes, the ratio of stakeless matches, and the recurrence ratio of teams in knockout rounds. A simulation method is applied using the teams, their seeding, and Elo ratings in the 2020/21 and 2021/22 Champions League seasons. Results suggest that the 2024/25 reform improves CB, especially in match uncertainty and the occurrence of stakeless matches. In comparison, the Star League of the European Super League concept of December 2023 is superior concerning average match uncertainty. However, it has a worse CB regarding stakeless matches and dynamic CB. Reasons and suggestions for improvement are also discussed.}, year = {2024}, eissn = {1552-7794}, orcid-numbers = {Gyimesi, András/0000-0002-6333-3318} } @article{MTMT:34786003, title = {Exploring hidden pathways to sustainable manufacturing for cyber-physical production systems}, url = {https://m2.mtmt.hu/api/publication/34786003}, author = {Pedone, Gianfranco and Váncza, József and Szaller, Ádám}, doi = {10.1016/j.heliyon.2024.e29004}, journal-iso = {HELIYON}, journal = {HELIYON}, volume = {10}, unique-id = {34786003}, year = {2024}, eissn = {2405-8440}, orcid-numbers = {Váncza, József/0000-0003-0054-0560; Szaller, Ádám/0000-0001-9555-4070} } @mastersthesis{MTMT:34741383, title = {Preference modelling with a graph theoretic approach}, url = {https://m2.mtmt.hu/api/publication/34741383}, author = {Szádoczki, Zsombor}, publisher = {Budapesti Corvinus Egyetem}, unique-id = {34741383}, year = {2024}, orcid-numbers = {Szádoczki, Zsombor/0000-0003-2586-5660} } @article{MTMT:34735759, title = {Statisztikus tanuláselmélet I. rész.

The Euclidean index is proposed to reward quality over quantity, while the rectangle index can be an appropriate measure of core performance. Their differences are highlighted through an axiomatic analysis and several examples. Our approach also requires a weighting scheme to compare different achievements. The methodology is illustrated by studying the knockout stage of the UEFA Champions League in the 20 seasons played between 2003 and 2023: club and country performances as well as three types of competitive balance are considered. Measuring competition at the level of national associations is a novelty. All results are remarkably robust concerning the bibliometric index and the assigned weights. Since the performances of national associations are more stable than the results of individual clubs, it would be better to build the seeding in the UEFA Champions League group stage upon association coefficients adjusted for league finishing positions rather than club coefficients.}, year = {2024}, eissn = {1613-9178}, orcid-numbers = {Csató, László/0000-0001-8705-5036; Petróczy, Dóra Gréta/0000-0002-8182-3791} } @article{MTMT:34267248, title = {Club coefficients in the UEFA Champions League: Time for shift to an Elo-based formula}, url = {https://m2.mtmt.hu/api/publication/34267248}, author = {Csató, László}, doi = {10.1080/24748668.2023.2274221}, journal-iso = {INT J PERF ANAL SPOR}, journal = {INTERNATIONAL JOURNAL OF PERFORMANCE ANALYSIS IN SPORT}, volume = {24}, unique-id = {34267248}, issn = {2474-8668}, year = {2024}, eissn = {1474-8185}, pages = {119-134}, orcid-numbers = {Csató, László/0000-0001-8705-5036} } @article{MTMT:34231363, title = {A lexicographically optimal completion for pairwise comparison matrices with missing entries}, url = {https://m2.mtmt.hu/api/publication/34231363}, author = {Ágoston, Kolos Csaba and Csató, László}, doi = {10.1016/j.ejor.2023.10.035}, journal-iso = {EJOR}, journal = {EUROPEAN JOURNAL OF OPERATIONAL RESEARCH}, volume = {314}, unique-id = {34231363}, issn = {0377-2217}, year = {2024}, eissn = {1872-6860}, pages = {1078-1086}, orcid-numbers = {Csató, László/0000-0001-8705-5036} } @article{MTMT:34214624, title = {How to choose a completion method for pairwise comparison matrices with missing entries: An axiomatic result}, url = {https://m2.mtmt.hu/api/publication/34214624}, author = {Csató, László}, doi = {10.1016/j.ijar.2023.109063}, journal-iso = {INT J APPROX REASON}, journal = {INTERNATIONAL JOURNAL OF APPROXIMATE REASONING}, volume = {164}, unique-id = {34214624}, issn = {0888-613X}, year = {2024}, eissn = {1873-4731}, orcid-numbers = {Csató, László/0000-0001-8705-5036} }
