Abstract

A robust optimization procedure that uses the expected value of Taguchi's loss function in formulating and solving large, computationally intensive, nonlinear optimization problems whose analysis is based on a linear system of equations is investigated. An efficient solution scheme that uses approximate expressions for the gradients and employs a fast reanalysis technique for their evaluation is introduced. This approach is validated by solving a simple minimum cost welded beam design problem. The method is then used to obtain the optimal shape of an engine connecting rod subject to stress, buckling and geometric constraints. The methodology presented is expected to save time and reduce computational effort.
