Reduced Order Modeling, Simulation and Optimization of Coupled Product development today is increasingly based on simulation and optimization of virtual products and processes (digital twins) that are described via mathematical models that encode the real physical product/process as well as free parameters that are used in optimization and control. Deeply refined mathematical models are required to understand and simulate the true physical processes, while for control and optimization less refined models need to be employed to handle the complexity. To achieve best performance of mathematical modeling, simulation and optimization (MSO) techniques, in particular in the industrial environment, a complete model hierarchy would be ideal which contains very fine and very coarse models and which can be used both for simulation and optimization on computers in an effective way. The currently most favored way in industrial applications to achieve such a model hierarchy is to use a sufficiently fine parameterized model and then to use model order reduction (MOR) techniques to tune the fine model to the accuracy, complexity and computational speed in simulation and parameter optimization. Although the mathematical models differ strongly in applications and industrial sectors, there is a common framework via an appropriate representation of the physical model via equations and functions. The main objective of this program is to further develop this common framework and, driven by industrial applications from different sectors, to lift mathematical MSO and MOR to a new level of quality and to train the next generation of researchers in this approach. A particular feature of the program is the treatment of high dimensional and coupled systems that describe different phenomena on different scales. Such systems present a major challenge for simulation and optimization and require new MOR techniques.
