【摘要】:考虑到柔性作业车间分批调度中不同工序具有各自合适批量大小,提出了基于工序分批调度的概念,建立了以关键路径工序为中心的分批调度模型。该模型动态更新可加工工序子批集,同时更新可选加工机器,及时调整加工路线,为不同工序安排大小合适的批量,以达到优化完工时间、有效降低总加工批次的目的。实验结果表明,相比基于工件分批的调度,该模型在优化最长完工时间、提高机器利用率的同时,大幅减少了总加工批次数量(42%),降低了车间调度管理的复杂度。
[Abstract]:Considering the appropriate batch size of different processes in the flexible job shop scheduling, the concept of batch scheduling based on process is proposed, and a batch scheduling model is established with key path processes as the center. The model dynamically updates the set of processing procedures, updates the optional machining machine, and adjusts the processing route in time. In order to optimize the completion time and effectively reduce the total processing batch, the experiment results show that the model can reduce the number of total processing batches (42%) and reduce the management of job shop scheduling, while optimizing the maximum completion time and improving the machine utilization ratio. Heterozygosity.
