摘要: 四向穿梭车系统进行批量出库作业时,系统出库订单的执行顺序不同,四向穿梭车与提升机之间的交互作业时长将会不同,进而影响系统的出库作业时间。根据四向穿梭车系统批量出库的作业流程,以批量订单出库顺序为变量,系统出库时间为目标函数,建立了一种系统订单排序优化模型;针对这个模型的特点,采用改进的遗传算法进行求解,进而得出系统的最优出库顺序;通过改变系统的相关参数分别测试该方法的优化程度,相较于优化之前的订单出库顺序,系统的出库效率至少提升20%。

Abstract: During the batch outbound operations of the four-way shuttle system, the different execution order of the system's outbound leads to the different interaction time between the four-way shuttle and the hoist will be different, which will affect the system's outbound operation time. According to the operation process of batch outbound, with the order of batch order outflow as the variable and the system outflow time as the objective function, a system order sort optimization model i established. Based to the characteristics of the model, with the improved genetic algorithm, the optimal order of the system is obtained. By changing the relevant parameters of the system, the optimization degree of the method is tested separately. Compared with the previous rorder sequence, the system's delivery efficiency is improved by at least 20%.
