| Abstract: | The raw material purchasing planning problem is search for the minimum-cost raw materials purchasing plan. The features of raw materials purchasing plan problem of the large-scale steel-iron enterprises are multi-item, large-quantity and high-cost. This paper formulates this raw material purchasing plan problems. The contributions of this paper include: (1) In the viewpoint of the supply chain, considers the logistics of raw materials before iron to formulate the problem. (2) In the solution approaches, because of the size of the problem is too large, a column generation-based approach is proposed and used. Computational results of a practical problem show that the model and approach are effective. |
