Resumo
This contribution aims at aid the development of robust optimization and decision making techniques of mechanical system when these are subject to uncertain information. In this case a novel approach is proposed regarding a fuzzy logic optimization strategy. The uncertain information of the considered mechanical systems is treated as fuzzy variables. Consequently, the associated optimization problem is described as a fuzzy function that maps the fuzzy inputs. The proposed technique is applied to the design of a robust welded cantilever beam. This numerical study illustrates the versatility and convenience of the proposed fuzzy logic optimization strategy.
