Solution

Problem decomposition by means of hierarchical planning pyramid
The selected concept follows a hybrid scheduling approach combining three planning levels with different planning horizons as well as planning accuracies to provide robust production plans on the one hand and flexible reaction strategies in case of unexpected events or decreasing plant performances on the other hand.

Architecture of DynReAct system
All components were integrated in a common framework. A snapshot component providing the per-coil information required for planning and scheduling yields as interface to the production.
