# Top institutions in operations research, 2023–2025

Universities and other research institutions ranked by the papers their authors published in the 49 tracked operations research journals in each year from 2023 to 2025, by publication date and OpenAlex affiliations; a paper counts once for each institution (and country) among its authors. Built from the site's archive of every paper of these journals and rebuilt daily.
