摘要: 针对目前综合调度研究中没有考虑存在预启动设备的情况,忽略预启动时间对整体加工时间影响的问题,提出存在预启动设备的综合调度算法。该算法在预启动设备处于空闲状态时采用提出的预启动长路径优先策略,在预启动设备处于工作状态时采用提出的预启动短路径优先策略,以提高预启动设备的并行化和减少了设备的预启动次数;采用提出的调整序列确定策略,确定产生设备空闲时间段的工序为调整目标;采用提出的可调序列工序调整策略,对产生设备空闲的工序的前序工序按层序对其加工时间进行调整,以提高设备的利用率。实例说明提出的算法解决了存在预启动设备的综合调度问题,有一定理论和实际意义。

Abstract: Since the current pre-start equipment is not considered in the study of comprehensive scheduling, and the effect of pre-start time on the overall processing time is ignored, a comprehensive scheduling algorithm with pre-start equipment is proposed. The algorithm adopts the proposed pre-start long path priority strategy when the pre-start device is in the idle state, and uses the proposed pre-start short path priority strategy when the pre-start device is in the working state to improve the parallelization of the pre-start device and reduce the device The number of pre-launches; use the proposed adjustment sequence determination strategy to determine the process that generates the equipment idle time period as the adjustment target; Adopting the proposed adjustable sequence process adjustment strategy, the processing time of the predecessor process that generates equipment idleness is adjusted according to the sequence to improve the utilization rate of equipment. An example shows that the algorithm proposed solves the problem of comprehensive scheduling of pre-start devices, and has certain theoretical and practical significance.

Key words: pre-start device, pre-start path, pre-start time, processing time adjustment, integrated scheduling algorithm
