Stochastic optimization - how to improve computational efficiency?
Abstract:
In order to guarantee the robustness of highly optimized structural designs it is essential to incorporate the treatment of stochastic uncertainties into the optimization process. Depending on the possible consequences of structural failure, the computational effort to estimate the failure probabilities and hence the cost of failure consequences may be very large. This is aggravated by the fact that the procedure may have to be repeated frequently as governed by the progress of the optimization algorithm. Hence methods to reduce the computational effort are urgently needed. The lecture will outline several possibilities, and will focus on the application of response surface methods for reliability-based structural optimization. Some examples will demonstrate the applicability of this approach.
