摘要: 为了减少交叉环单向循环搬运系统的干涉并提高系统效率,着重研究了交叉环单向循环搬运系统中小车间干涉及调度优化问题,对两种基本调度算法(随机调度、顺序调度)进行干涉分析,提出了干涉发生情况下车辆调度的最优调度算法—交换顺序调度算法不同的调度算法影响着小车间的干涉情况,进而影响了整个柔性制造系统的搬运效率。实验显示:交换顺序调度算法优于随机调度算法和顺序调度算法,既能减少了系统的干涉又提高了系统搬运效率,实现系统优化。

Abstract: To decrease the interference and improve the performance of a unidirectional circulation-type material handling system on a single loop with a shortcut, the interference and scheduling problem between AGVs are studied. According to the actual situation of material handling system, the interferences of two scheduling rules (random rule and order rule) are analyzed. An optimal scheduling rule under the interference case—exchange order rule is proposed. Different scheduling rules have an influence on the interference between AGVs and then have an important effect on the efficiency of the whole system. Experiment results show that the exchange order (E-Order) rule is better than the random rule and the order rule, which can decrease congestion (interference time), improve the handling efficiency and achieve the optimal performance.

Key words: material handling system, scheduling, short-cut, optimization
