Abstract

The problem of steel cold rolling production capacity is an important issue in steel production. In this paper, mathematical modeling is carried out to meet the actual constraints of production process, inventory, flow balance, etc. And to determine the type and corresponding output of a certain product in each machine in every process in the production network, then obtain the inventory of each product between processes. The objectives of the model are to maximize unit capacity and minimize production switching costs. Differential evolution is a population-based evolutionary algorithm. It has the characteristics of recording the best solution during searching history and exchanging and sharing information within the population. That is, the optimization problem can be solved through the cooperation and competition among individuals within the population. In this paper, the differential evolution algorithm is modified for steel cold rolling production line capacity planning problem, the modified differential evolution algorithm comparing with other multi-objectives genetic algorithm. The results show that the proposed algorithm is superior to other standard genetic algorithm and can fast convergence, thus verified the feasibility and effectiveness of the algorithm.
