摘要

为了对炼钢-连铸动态调度进行仿真,分析了炼钢-连铸动态调度系统的特征,重点讨论了基于Witness对炼钢-连铸动态调度系统仿真时的关键问题,即工艺路径设置、断浇修复技术、动态扰动设置和调度结果可视化.源于钢铁企业的实际生产数据证明了Witness仿真软件对解决炼钢-连铸动态调度问题是可行且有效的,通过对软件自身优化算法进行比较,结果表明采用不同优化算法,其对应的解的质量和收敛效率不同.%To simulate the dynamic scheduling of steelmaking and continuous casting, the characteristics of dynamic scheduling for steelmaking and continuous casting are analyzed. The key issues are discussed as follows: the setting of the routing, repairing technology, the setting of the disturbance factors and the visualization of the scheduling result At last, the data from the iron and steel plants proves the effectiveness and feasibility of the simulation model. Through the comparison of different optimization algorithms, the quality and convergence efficiency of solution is different according to different algorithms.
