Aiming at making an integrated production plan for steelmaking-continuous casting-hot rolling (SM-CC-HR) process in the iron and steel industry, a novel integrated planning framework based on the harmony search algorithm and the prediction model is proposed. In our approach, we use a crude prediction model to evaluate the performance of a hot-rolling planning (HRP) problem in the process of optimizing the steelmaking-continuous casting planning (SCP) problem, and use a knowledge-based simulation model to obtain a solution of the HRP problem. An Objective-Directed Strategy (ODS) is introduced into the local search process of the harmony search algorithm for balancing the exploitation and exploration of the solution space. Numerical computation experiments on practical production data from an iron and steel enterprise show that more than 10% higher effectiveness and efficiency of the proposed approach are obtained compared with the normal practices followed in the company relying on human expertise.Index Terms -steelmaking-continuous casting-hot rolling; integrated planning; harmony search algorithm; prediction model.

“…Equation (7) is used to calculate the particle's new velocity according to its previous velocity and the distances of its current position from its own best experience (position) and the group's best experience. Then, the particle flies toward a new position according to Equation (8). The performance of each particle is measured according to a predefined fitness function, which is related to the problem to be solved.…”

The batch machine scheduling of continuous caster with flexible jobs is first proposed based on its character. The difference with classical problem is first summarized. The preprocess of the problem based on rule is proposed, and then the mathematical model with minimizing setup costs is proposed. To improve the efficiency of local search, the particle swarm optimization (PSO) is introduced, and then the PSO combined with heuristic is embedded into the iterated local search (ILS) to solve the problem. The solution space is divided into many subspaces based on the charge information, and then the subspaces are integrated after local search. The maximum number of iteration is introduced as stopping condition. Then, the proposed hybrid algorithm and ILS are compared, and the changing of number of generation, learning factors, and the maximum number of iteration are also tested, respectively. Finally, the simulation results show that the proposed algorithm can solve the problem efficiently.
