- W2261818730 abstract "Robust design optimization problems are known to be computationally expensive as it involves identification of designs that are both good in performance and at the same time have minimal variance in performance among its neighbors. Assessment of performance variance for every design is computationally expensive as numerous designs in the neighborhood needs to be assessed and evaluation of a design could itself involve expensive analysis based on computational fluid dynamics (CFD) or finite element methods (FEM). Approximations can be used in lieu of actual assessments to compute the variance of performance among neighboring designs and their accuracy can be maintained via periodic training. In this paper, we investigate the performance of a radial basis function (RBF) surrogate model and compare its performance with models relying on actual evaluations and a first order Taylor series model. Our optimization model relies on a population based, zero order, stochastic algorithm and it has been implemented using C++ and MPI to make use of multiple processors. Two engineering design optimization examples have been used as case studies to observe the behavior of the surrogate models. Preliminary observations suggest that the Taylor series model is capable of containing the computational cost within affordable limits while maintaining an acceptable level of accuracy. The RBF model did not perform well partly due to its global approximation scheme." @default.
