Multi-AGVs Conflict-Free Routing and Dynamic Dispatching Strategies for Automated Warehouses

Automated Guided Vehicle System (AGVS) has been playing a vital role in many applications such as flexible manufacturing systems and automated warehouses. Efficient vehicle routing and dispatching are two important aspects when designing an AGVS. Based on zone control mode, this paper proposes a conflict-free routing strategy to improve the system efficiency with the ability to avoid loops. A dynamic dispatching strategy is proposed which can find a suitable AGV to conduct the task to decrease the total traveling distance and the waiting time. Simulations are carried out to verify the effectiveness of the strategies.
