Chapter 11: Applications in Other Engineering Disciplines

In this chapter, we discuss applications of surrogate-assisted optimization methods considered in this book for solving multi-objective design problems in other engineering areas. A common issue is a high cost of computational models that prevents the straightforward applications of the off-the-shelf algorithms such as population-based metaheuristics. On the other hand, utilization of the methods described in Chapters 7 and 8 along with variable-fidelity simulations allows for yielding the Pareto-optimal designs in practically acceptable timeframes. Three specific case studies are presented, including multi-objective design of impedance matching transformer using sequential domain patching (SDP), optimization of compact microstrip coupler by means of Pareto front exploration, and two-objective design of transonic airfoils using response surface surrogates and co-Kriging.
