针对废钢铁再制造中电弧炉出钢延迟的生产扰动问题,以断浇最小化、重调度前后加权差异最小化为目标,建立冲突消除规则和断浇修复规则,在工艺动态约束满足下设计了右移受影响炉次和炉次重分配两类重调度方案。仿真实验验证了算法的有效性,并得出:延迟时间越长,断浇可能性越大,重调度前后差异也越明显,并更倾向于选择炉次重分配;生产环境需求决定着权重系数大小设置;冶炼、精炼工序双炉次重分配在极端条件下可成为最优方案。
Aiming at the delayed production disturbance of EAF in scrap steel remanufacturing, aiming at minimizing the weight of cut-off and minimizing the weighted difference before and after re-scheduling, a conflict elimination rule and a rule of breaking and pouring are established, which are designed under the dynamic constraint of process Right shift affected by the furnace and re-distribution of two types of re-scheduling program. Simulation results show the effectiveness of the proposed algorithm. The results show that the longer the delay time, the greater the possibility of pouring, and the more obvious the discrepancies between before and after rescheduling, and the more inclined to choose the second reallocation of furnace. The production environment demand determines the weight coefficient Size setting; smelting, refining process double furnace secondary redistribution in extreme conditions can be the optimal solution.
