Design and Control of Automated Guided Vehicle Systems: A Case Study
Abstract: 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.
