本文以集装箱自动化码头岸边集装箱运输为研究对象，对自动导引车系统的设计与控制进行了研究。我们首先在区域控制框架中建立了AGV系统的事件驱动模型。然后，为集装箱码头AGV的工作空间精心设计了多个路网(引导路径)布局。基于我们的区域控制模型，提出了一种交通控制策略，将AGV之间的运动冲突消解与路径问题解耦。建立了以车辆行驶距离和运输时间最小为目标的路径算法。根据一组定义的系统性能测量，计算机仿真证明了集成设计和控制的有效性。最后，我们指出了改善目前结果的几种可能性。
In this paper, we study the design and control of automated guided vehicle (AGV) systems, with the focus on the quayside container transport in an automated container terminal. We first set up an event-driven model for an AGV system in the zone control framework. Then a number of layouts of the road network (guide-path) are carefully designed for the workspace of the AGVs in a container terminal. Based on our zone control model, a traffic control strategy is proposed, which decouples the motion conflict resolution among the AGVs from the routing problem. A routing algorithm is also constructed with the goal of minimizing the vehicle travel distances and the transportation time. The efficiency of the integrated design and control is demonstrated by computer simulations in terms of a set of defined measures of system performance. Lastly, we point out several possibilities towards improving our current results.
