Covering Pareto Sets by Multilevel Subdivision Techniques

In this work, we present a new set-oriented numerical method for the numerical solution of multiobjective optimization problems. These methods are global in nature and allow to approximate the entire set of (global) Pareto points. After proving convergence of an associated abstract subdivision procedure, we use this result as a basis for the development of three different algorithms. We consider also appropriate combinations of them in order to improve the total performance. Finally, we illustrate the efficiency of these techniques via academic examples plus a real technical application, namely, the optimization of an active suspension system for cars.The authors thank Joachim Lückel for his suggestion to get into the interesting field of multiobjective optimization. Katrin Baptist as well as Frank Scharfeld helped the authors with fruitful discussions. This work was partly supported by theDeutsche Forschungsgemeinschaft within SFB 376 and SFB 614.
