| Abstract: | Deadlock problems of zone control unidirectional AGV systems are discussed in this paper. Deadlocks of two types are classified from the perspective of shared resources: guide path zones and buffers. A special class of Petri nets, attributed Petri nets (APN), is defined and used to represent the current state and to generate future states of zone control AGV systems. The authors propose an algorithmic procedure to predict in real time and to avoid deadlocks that are caused by sharing guide path zones in zone control AGV systems. |
