Proc. ASME. DETC97, Volume 2: 23rd Design Automation Conference, V002T29A012, September 14–17, 1997
Paper No: DETC97/DAC-3961
...Abstract Abstract In structural design, expensive function evaluations can be replaced by accurate function approximations to facilitate the effective solution of multiobjective problems. In this paper we address the question: How can we solve multiobjective shape optimization problems...

... to build global approximations of computationally expensive computer analyses. Three structural design examples are presented to test the predictive capability of these metamodels for use in design optimization. The reported results confirm that these spatial correlation metamodels can produce sufficient...
