... the proposed sensitivity combined with an accurate surrogate model can be used to solve an RBDO problem. However, there also exist some drawbacks of the proposed method as well as advantages mentioned above. First, it may not be easy to obtain accurate surrogate models especially when the true response...

...Chun-Min Ho; Kuei-Yuan Chan In this work, the presence of equality constraints in reliability-based design optimization (RBDO) problems is studied. Relaxation of soft equality constraints in RBDO and its challenges are briefly discussed, while the main focus is on hard equalities that cannot...
