【Abstract】 The blast furnace production planning problem is formulated as a linear programming model. The proposed model is different from those in the open literatures in the following five aspects. (1) Varieties of products are considered. (2) Multiple time periods are adopted. (3) Purchasing and inventory strategies are integrated into the model to satisfy requirements of supply chain management. (4) Considering the theory of the limit of pulverizing coke injection and the theory of minimal coke ratio, the corresponding constraints are formulated. (5) The influence of materials blending on the blast furnace production rate is considered. The solution to the model indicates a most economical (maximal profit) selection of input materials in blast furnace production. Finally, an application example is taken to illustrate the model. 更多还原
