Abstract
This research paper explores the assessment of 21st century skills in civil engineering students using the Analytic Hierarchy Process (AHP) and Analytic Hierarchy Process with fuzzy sets (FAHP) as multi-criteria decision-making (MCDM) tools. The main criteria considered in the MCDM problem were critical thinking, problem solving, creativity and innovation, communication, and collaboration. The results consistently highlighted the utmost importance of communication and collaboration, as they emerged as the primary criteria in both the AHP and FAHP methodologies. Conversely, creativity and innovation (CI) were ranked with the lowest importance in both methodologies. The selection between AHP and FAHP depends on the decision problem's nature and the decision-makers' preferences. FAHP may be more suitable when the decision problem involves difficult-to-quantify or subjective preferences.
