炼钢—连铸区段生产调度与计算机仿真

炼钢-连铸区段的生产调度包括炉次计划、浇次计划的生成和时间、设备的分配,以及针对各种扰动的动态调整.根据钢种和规格的限制,提出了最优炉次计划模型,并采用禁忌搜索算法进行求解;根据炉次计划和连铸机连浇限制,生成浇次计划;根据炉机匹配和等待时间最小原则,生成静态调度甘特图,并对仿真过程中出现的出钢延迟提出了动态调度的策略和算法.仿真结果表明,基于模型的动态调度策略能够有效地解决出钢延迟问题.

Computer-aided simulation of steelmaking-continuous casting production scheduling

Steelmaking-continuous casting production scheduling includes the drawing of a furnace charge plan and a cast plan,the allocation of time and equipments,and the dynamic adjustment to kinds of disturbances.An optimal furnace charge plan model was established based on the constraints of grade and specification and an algorithm with taboo search was used to solve the model.The cast plan was presented according to the furnace charge plan and the limitation of continuous casting.The principles of matching between converters and casters and minimizing the waiting time were used to draw the Gantt chart of static scheduling. A dynamic scheduling strategy and its algorithm were proposed for tapping tardiness in the simulation process. Simulation result shows that the strategy based on the model effectively solves the problem of tapping tardiness.
