Multi-criteria decision making/selection using weighted sum method and team-compromise instrument

Abstract

Multi-criteria decision making based on values and preferences of the decision makers has been a major challenge in selecting the optimal material for any engineering product design. However, to evaluate the criteria weights by importance as a major valuable tools in decision making among the team members are another problem being faced in group decisions. In this paper weighted-sum method is adopted for solving material selection problems. The team-compromised approach is introduced as a parameter in the model by combining the subjective weights and objective weights of importance of the criteria in the decision making process. Two examples are presented to illustrate the efficacy of the model.  The results shows that the proposed model is capable of selecting the best material taking into account the material selection criteria.
