摘要

With the development of production technologies in iron and steel enterprises, integrated production technology comes into use for steelmaking and continuous casting as well as hot rolling. In the paper, the limitation of the traditional existing planning and scheduling methods which separately consider the process of steelmaking-continuous casting or hot rolling is broken through. A scheduling model is presented to integrate the three working procedures, namely, steelmaking, continuous casting and continuous rolling. Then lagrangian relaxation algorithm is proposed to get the optimal solution of the scheduling model. Finally, numerical examples are given to demonstrate the effectiveness of the integrated model and optimization methods.
