Modelling and control automated guided vehicle traffic at a container terminal

Container terminal logistics has been a prominent field of research and the term Automated Guided Vehicle Systems has become a keyword in publications. This paper is devoted to the modelling and control of automatic guided vehicles (AGVs) assuming that the transportation system configuration is given as well as transportation task. AGVs follow a guide-path while controlled by a computer that assigns route, tasks, velocity, etc. The AGV motion can be described as the set of discrete events and states. Some of these states can be undesirable such as deadlocks and collisions. By applying adequate control policy to avoid such states and block the vehicles motion only in the case of dangerous situation it is able to improve the container terminal's overall logistic efficiency. The Coloured Petri net is used for the process control specification.
