针对炼钢厂在不满负荷生产的情况下，缺少相应指导原则编排生产计划的问题，提出一种基于钢包运行稳定性的生产计划优化方法。首先，通过对炼钢厂钢包周转过程的分析，提出在线运行钢包个数的计算方法。然后，分别针对单台铸机和两台铸机顺序开浇的两种情况，分析生产计划对钢包运行状态的影响，建立计算模型。以某炼钢厂生产计划为例进行解析，并以钢包运行稳定性为评价参数，利用遗传算法对生产计划进行优化。结果表明，优化的生产计划可以减少钢包使用个数及其温度波动，减少烘烤煤气消耗量和降低转炉出钢温度，提高钢水温度的控制水平。

For the problem of the lack of guiding principle of production schedule in the case of non-full production in steelmaking plant,the optimization method of production schedule based on ladle running stability Was proposed.First,the computational method of the number of online operation ladle Was proposed by analyzing ladle turnaround process.Second,the impact of production schedule on ladle running Was analyzed for the production schedule of single casting machine and tWo casting machine,and the computational model Was proposed.Finally,the method Was used to optimize actual production schedule of a steelmaking plant.The results shoWed that using genetic algorithm based on ladle running stability,the fluctuation of the number of ladle is reduced,the fluctuation of ladle thermal state is reduced,baking gas is saved,the temperature of BOF endpoint is reduced and the level of control the temperature of molten steel is improved.
