摘要： 针对高炉布料过程中人工决策无法得到稳定、满意的径向矿焦比值及炉况发生变化时不能及时做出准确的布料调整，提出了基于操作优化的高炉布料仿真和决策系统.以高炉多层布料料面对应的径向矿焦比值与满意值的偏差最小为目标函数，建立高炉布料操作优化模型，用差分进化算法对该模型求解.本系统在某高炉实际运行后提高了炉况的稳定性，满足了工业现场科学稳定地控制径向矿焦比等技术指标的要求，同时在炉况变化时及时给出了布料调整方案.在工业实际运行中验证了该系统的有效性.

Abstract: For the difficulty to obtain a stable and satisfying ore to coke ratio indicator by manual decisions and unable to make the burden distribution adjustment timely and accurately， a simulation and decision-making system based on operation optimization was proposed in burden distribution. Taking the minimum deviation between the index value and the optimal value of practical burden surface as the objective function， an operation optimization model was built. A differential evolution algorithm was used to solve the proposed model. The system can improve the stability of the furnace condition after the actual operation of blast furnace， meet the requirements of scientific and stable control of ore to coke ratio and give the adjustment program of burden distribution in time when the furnace condition changes. The practical application results showed the effectiveness of the system.

Key words: burden distribution of blast furnace, simulation system, actual system, simulation experiment, operation optimization
