Enhanced multiobjective technique for multidisciplinary design optimization

Research output: Contribution to journalArticlepeer-review

1 Scopus citations


In the Kreisselmeier-Steinhauser (K-S) function approach all of the objective functions are already weighted, which eliminates the need for user input in setting up the problem. However, in a realistic design application, it would be advantageous to have a method where a designer could emphasize specific design criteria relative to the others. In the present work, the K-S technique has been enhanced to provide such a capability by using weight factors that enable increased emphasis on specific objectives during the optimization process. The enhanced technique has been demonstrated on a HCST for minimum sonic boom and improved aerodynamic performance.
