Improving fuel utilization in steel mill operations using linear programming
用线性规划为美国中西部一家大型钢铁厂制定燃料分配方案，通过更有效利用生产过程中产生的副产品气体（高炉煤气和焦炉煤气）来降低总燃料成本。
Abstract This paper describes the use of linear programming to improve the fuel utilisation at a major Midwestern steel mill. In particular, linear programming is used to determine an efficient fuel allocation plan for this steel mill, which reduces the total fuel costs for the steel mill operations. The efficient fuel allocation plan that is developed utilises two externally purchased fuels: natural gas and fuel oil, and two gases: blast furnace gas and coke plant gas, which are internally generated as natural by‐products of the production process. Test results from the application of the linear programming model are presented and discussed, and indicate that considerable cost savings can be achieved by utilizing a fuel allocation plan which more effectively utilizes the by‐product gases which are produced within the steel making process.
