Goal of the research is the development of evaluation methods of coupled partial models, focussing on the combination of individual partial model qualities into a global quality measure. The definition of coupling quality of partial models, especially in case of strong interations, is a major step pf the reseach.
Variance-based sensitivity analysis in combination with the representation of coupled partial models using graph theory allows for the determination of the influence of classes of partial models on specific response quantities as well as the quantification of the influence of different coupling schemes on the total prognosis.
The application of the developed methods allows for the integration of the individual qualities of the partial models in order to calculate a total measure of prediction quality for the global model, which is composed of various partial models. The total quality measure is a result of the individual qualities of the partial models, their influences on the response quantities, and the quality of coupling.
