摘要: 为优化轨道门吊调度方案,降低安全距离对装卸设备作业的干扰,建立轨道门吊柔性范围混合调度模型,通过动态调整轨道门吊间距离,确定装卸任务分配方案。模型应用遗传算法,建立时间-位置矩阵近似分析各时间点轨道门吊的位置。为验证模型有效性,选取一个包含65个装卸任务的算例。计算结果表明:柔性范围混合调度模型在保证轨道门吊间安全距离的前提下,使装卸任务总时间降低4.10%,轨道门吊空驶时间减少7.24%。

Abstract: In order to optimize the scheduling scheme of rail-mountedgantry crane and reduce the interference of safe distance to the operation ofloading and unloading equipment, a hybrid scheduling model of flexible range of rail-mountedgantry crane was established, and the loading and unloading task allocation scheme was determined by dynamically adjusting the distance between rail-mounted gantry cranes. The model usedgenetic algorithm to establish the time-position matrix to approximate the position of the gantry crane at each time point. To verify the validity of the model, an example with 65 shipment tasks was selectedto carry out case study. The results show that the flexible range hybrid scheduling model can reduce the total time of loading and unloading tasks by 4.10% and the deadhead time of rail-mountedgantry crane by 7.24% on the premise of ensuring the safe distance between rail-mountedgantry cranes.
