Abstract: Selection of material for a specific engineering component, which plays a significant role in its design and proper functioning, is often treated as a multi-criteria decision-making (MCDM) problem where the most suitable material is to be chosen based on a given set of conflicting criteria.For solving these MCDM problems, the designers do not generally know what should be the optimal number of criteria required for arriving at the best decisive action.Those criteria should be independent to each other and their number should usually limit to seven plus or minus two.In this paper, five material selection problems are solved using three common MCDM techniques to demonstrate the effect of number of criteria on the final rankings of the material alternatives.It is interesting to observe that the choices of the best suited materials solely depend on the criterion having the maximum priority value.It is also found that among the three MCDM methods, the ranking performance of VIKOR (Vlse Kriterijumska Optimizacija Kompromisno Resenje) method is the best.
