基于环岛策略的自动化码头AGV路径仿真优化

摘要

随着自动化集装箱码头的广泛使用,水平运输环节逐渐成为制约码头作业效率的新瓶颈.为避免AGV在交叉路口产生排队等待,采用虚拟环岛策略,并根据AGVs运行机理,考虑边装边卸作业工况,利用eM-Plant仿真软件建立包括岸桥、AGV 和堆场在内的集装箱码头仿真模型,最后通过变动支路数量和位置,来比较 AGV 不同行驶路径对码头作业效率产生的影响.研究结果表明:AGV 选择不同的行驶路径在一定程度上影响着码头的作业效率.实验结果为提高码头作业效率,优化码头前沿路径提供一定参考依据.%With the widespread using of automated container terminal, the horizontal transportation has gradually become a new bottleneck which restricting the port efficiency. This paper mainly study the optimization problem of the automatic container terminal. First, used the virtual transportation circle strategy to avoid AGV congestion in intersection. Then, based on the running mechanism of AGVs, considered load and unload at the same time, used eM-Plant simulation software build a container terminal simulation model which includes quay crane, AGV, and yard. Finally, by changing the shortcut quantity and location, using the simulation to compare the effects of different AGV driving routes to the port efficiency. Experimental results show that select different driving paths certainly affect the port efficiency. The experimental results provide a reference for improving the efficiency of the terminal operation and optimizing the front path of the wharf.
