Abstract

The production of steel normally constitutes the inception of most Supply Chains in different areas. Steel manufacturing companies are strongly affected by bull whip effects. Due to nondeterministic incoming orders and changes of customer requirements on accepted orders, making the right decision at a certain stage can be the difference between earning or loosing a great turnover. Improving their operational efficiency is required to keep a competitive position on the market. Therefore, flexible planning and scheduling systems are needed to support these processes which are based on considerable amounts of data which can hardly be processed manually. Existing systems are dominated by centralized decision making processes, mostly data driven and often not modeling the business processes they should. MasDISPO_xt is an agent-based generic online planning and online scheduling system for monitoring of the complete Supply Chain of Saarstahl AG, a globally respected steel manufacturer. This paper concentrates on the creation and optimisation of heats and sequences as a presetting for the production inside the steelwork.
