Improved TOPSIS for Al-SiC Composite Material Selection
Abstract: This paper proposes a novel Multi-Criteria Decision-Making(MCDM) method for attaining accurate and reliable results on Al-SiC composite material selection. Many of the existing researches suggested some methods for determining weights for criteria objectively and dealt with various mathematical models for eliminating inter-criteria correlation. However, they still involve some considerable shortcomings not fitting in the reality. In this paper, in order to determine the weights of criteria, methods for both subjective …
