Material Selection Optimization Using Weighted Sum Method and Team-Compromise Instrument

Abstract

The main challenge of multi-criteria optimization application is the difficulty in selecting the optimal material for any engineering product design. However, to determine criteria weights without conflicts among the team members is another problem being faced in concurrent engineering. 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.
