The steel production of the German company Saarstahl AG, a global respected steel manufacturer, represents a Supply Chain which comprehends several time-critical and highly interference susceptible processes. Therefore, flexibility, robustness and fast reorganisation are indispensable requirements on a system responsible for the planning of production inside this Supply Chain to ensure acceptable costs and retain their respected position on this market. In this paper we present an agent-based generic solution for the planning and observation of the complete production process inside the steelwork Völklingen of Saarstahl AG. The presented system calculates solutions for given daily target schedules – based on the concrete orders by the customers – by a combined distributed online planning and scheduling algorithm, and, additionally, performs the observation of its realisation. Moreover, the presented real-time multiagent system supports the reorganisation after operational faults ...
