Abstract: Due to unavoidable uncertainties related to material properties and
manufacturing processes, the robustness of the optimal solution must be
considered when designing electromagnetic devices. In this paper, the
worst-case optimisation (WCO) and the worst-vertex-based WCO are proposed to
evaluate the robustness of both performance and constraints under uncertainty.
To reduce computing times when searching for the robust solution a predicted
objective function is used, obtained with the help of a kriging algorithm which
explores the searching space using the concept of rewards. Finally, to avoid
some of the shortcomings of WCO, the concept of average performance evaluation
is developed.
