Material Selection Based on Multicrieria Decision Methods for Brake Disc Manufacture

Abstract:

This study evaluates an alternative material in the manufacture of a brake disc in light SUV vehicles, using multicriteria methods; for which five candidate materials are taken into consideration. The multicriteria methods used are: multidisciplinary optimization and compromise solution (VIKOR), elimination and options that reflect reality (ELECTRE I), proportional complex evaluation (COPRAS), additive relationship evaluation (ARAS), multi-objective optimization is based on the radius analysis (MOORA) and the entropy method used for weighting the criteria. The best alternative is ASTM A536 according to the COPRAS, ELECTRE I and ARAS methods, due to its low density, good compressive strength and good thermal conductivity.
