The aim of this project was the development and implementation of the "Global Through-process Flatness Predictor and Coordinated Optimizer". This system should integrate all sub models including models of transfer conditions from process stage to process stage and perform a line-through process flatness prediction. However, analyses of the gained plate flatness in the various process routes showed that the reduction/evolution of flatness defects is nearly independent from the considered process route. Furthermore it has to be confirmed that flatness defects are not passed through the processing chain.
