Production Optimization and Scheduling across a Steel Plant

This paper focuses on the planning and scheduling optimization of two processes in steel production, the melt shop and hot rolling. Important steps and challenges of bringing a scheduling model from a conceptual idea to an industrial solution that steers the complete production of a steel plant on a day-to-day basis are covered. Moreover, we discuss the main development steps and the embedding of a mathematical model based solution into a production system. Finally, we present some results based on real-world data from an industrial implementation.
