Deadlocks in automated container terminals cause significant losses in port operational performance and thus, in order for the successful implementation of automated guided vehicle systems for container ports, it is crucial to prevent deadlocks. A graph-based representation of deadlocks is provided in this study, and deadlocks are prevented by imposing constraints in vehicle movements. Such constraints are embedded in the software controller by attaching control nodes. The simulation results show that the operational performances of container terminals may significantly be improved by the proposed controller.
