Computer-aided simulation of steelmaking-continuous casting production scheduling

Steelmaking-continuous casting production scheduling includes the drawing of a furnace charge plan and a cast plan,the allocation of time and equipments,and the dynamic adjustment to kinds of disturbances.An optimal furnace charge plan model was established based on the constraints of grade and specification and an algorithm with taboo search was used to solve the model.The cast plan was presented according to the furnace charge plan and the limitation of continuous casting.The principles of matching between converters and casters and minimizing the waiting time were used to draw the Gantt chart of static scheduling. A dynamic scheduling strategy and its algorithm were proposed for tapping tardiness in the simulation process. Simulation result shows that the strategy based on the model effectively solves the problem of tapping tardiness.
