Subproject A4

Mathematical Models and Methods for Optimal Combinations of Passive and Active Components

The goal of this subproject is the development of efficient mathematical optimization algorithms for a comprehensive and robust design of load-carrying structures to immunize them against uncertainty and to maximize resilience. In particular, dynamic loads are considered, complex active elements are positioned optimally and methods to identify model uncertainty are developed.
