In this research, a new decision support system was proposed to select different cutting fluids in the manufacturing environment. In this context, three studies were taken from the literature. Fifteen different multi-criteria decision-making techniques and four normalization methods were used to determine the best conditions for these studies. In terms of weighting criteria, a new hybrid criteria weighting method was proposed. The obtained rankings were compared with the Spearman correlation test. Compared to the literature results, the proposed strategy produced consistent results in terms of rankings (p < 0.05).
