In a first aspect, the present invention provides a unique algorithm that interactively takes into consideration the melt shot (MS) and the hot strip mill (HSM) constraints such that a balanced and feasible solution is reached for the whole Primary Area (MS and HSM) at once. In a second aspect, the invention takes a set of orders defined to be produced next in the Melt Shop area in a steel mill and groups them in small sets of orders with similar characteristics, called heats. Each order belongs to a heat. The system defines the precise moment that each heat has to be processed in each of its steps. In another aspect, the invention uses an event-driven based algorithm as a general approach for scheduling all the processing units with their specific constraints and the metallic units from hot coils to the finished products at the shipping areas. With a further aspect, the present invention provides a system that considers various constraints and assigns a precise start and finish time for each slab to be processed in each processing unit specified in the slab route.
