Hybrid intelligent scheduling method and its application for steelmaking and continuous casting

Under the technical constraints of steelmaking and continuous casting production, the hybrid intelligent scheduling method is established which includes rule-based expert systems, LP-based method with two stages and multi-layer fuzzy comprehensive evaluation for the production environment with multi-equipment, multi-process and complex production style, and the optimal solution is difficult to obtain within the rational time, an available and feasible solution can be obtained by this method. The intelligent scheduling structure is established by the hybrid intelligent scheduling method, and the software system is also designed and developed. Finally, the hybrid intelligent scheduling method is successfully applied to one large steel plant. Applied results show that the making plan time and waiting time for molten steel are highly shortened, and the utilization ratio of facilities is raised. The economic effect is good.
