The paper has significant methodological weaknesses, particularly in the justification of the fuzzy-AHP-TOPSIS model and the reliability of self-reported student data. The use of Fourier series expansion appears unnecessary and may have been included to add complexity without clear justification. Additionally, inconsistencies in statistical rigor, such as the absence of a consistency ratio in AHP, raise concerns about the robustness of the findings. I encourage the authors to address these issues to strengthen the study’s methodological rigor and improve the clarity and reliability of its conclusions.
