This paper proposes a new design of the bi-directional automated guided vehicle (AGV) system, in which two AGVs can exchange their loads, the scheduled transportation tasks and even their vehicle numbers when they are moving in opposite directions and stop in front of each other. With the exchangeable AGV (EX-AGV) system, the common problems such as conflicts and deadlocks no longer exist and lots of unnecessary waiting time and detours can be avoided. A model, a solution algorithm framework and some on-line control polices are proposed. A simulation of the EX-AGV system is carried out and the result shows that the system is of well performance.
