   abstract = "This article explores the methodological landscape of international university rankings by reconstructing and formalizing the computational pipelines of five widely used global systems (ARWU-ShanghaiRanking, Times Higher Education (THE), U.S. News Best Global Universities, QS World University Rankings, CWUR) and reviews mathematically principled alternatives to fixed-weight composite rank tables. For the major ranking systems, the study details indicator design, normalization and transformation mechanisms and weighted aggregation into final composite scores, highlighting how these design choices encode normative assumptions and drive cross-system discrepancies. Responding to critiques of single-score rank tables, the paper reviews non-aggregative and minimally aggregative paradigms that preserve multidimensionality and reduce misleading ordinal precision, including dominance-based methods (Pareto front, skyline and discriminative skyline ranking), categorical layering (Rainbow Ranking and RR-index), dashboard and group-based multidimensional systems (U-Multirank, CHE-style reporting, and CWTS Leiden Ranking), frontier efficiency models (DEA/FDH), and data-driven latent-dimension approaches (PCA, factor and Bayesian latent-trait models). The article also situates aggregated-ranking voting rules and weighted voting power indices as complementary formal tools for preference aggregation and influence analysis. Overall, it argues that global rankings should be interpreted as algorithmic evaluative frameworks rather than neutral measurements, and that dominance-, profile-, frontier-, and latent-variable approaches offer transparent and conceptually robust complements for multidimensional university evaluation. We aim to identify ranking methods that operate without human-chosen weights or subjective parameter choices, because such choices influence and often distort the resulting rankings."

   abstract = "University rankings are not only used as tools in academia and funding agencies, but they are popular readings in newspapers and magazines as well, plus they are of major importance for decision-making in academia. University rankings have been heavily criticized for a number of reasons, including that they are based on arbitrary choices about the key performance indicators, their special weights and so on. For these reasons, we argue that there is no meaning in ranking universities in an absolute ordered manner; instead universities should be ranked in ``sets of equivalence''. To this end, here we present a modified version of Skyline and Rainbow Ranking, named Bounded Skyline and Bounded Rainbow Ranking, respectively. The results are analyzed and discussed in comparison to traditional university rankings.",
