Multi-AGVs Collision-Avoidance and Deadlock-Control for Item-To-Human Automated Warehouse

Automated Guided Vehicle System (AGVS) is widely applied in many automated manufacturing systems, especially in the e-commerce warehouses recently. When multiple AGVs are running in the limited spaces, lots of issues involved in the traffic management, such as collision and deadlock, need to be well addressed. Based on the digraph model, this paper proposed some effective rules, and applied online control strategies to achieve these goals with both unidirectional and bidirectional paths. Simulations based on practical settings are carried out, and the results verified the effectiveness of rules and strategies.
