Nowadays, having the greatest product is something that everyone aspires to. Choosing the greatest product has become more difficult in the present day, since numerous products seem to have excellent specs as well. Thus, is generally regarded as an MCDM issue, where the best material is picked based on a given set of competing criteria, and this plays a vital part in its correct functioning. The designers of these MCDM challenges don't typically know how many criteria they should use to arrive at the best possible decision. It's best to limit the number of criteria to seven plus or minus two and make sure they're not interdependent. The Full Consistency Method (FUCOM) is a novel multi-criteria problem-solving approach presented in this research. In the model, two sets of constraints are required to meet the weight coefficients' optimum values. On the basis of pairwise comparisons of criteria, the model was validated by comparing it to two other subjective models (SAW and WASPAS).
