Design of Distributed Route Based on Un-utility Coefficient under an Uncertain Transportation Condition at Logistics Center for Autonomous AGVs

—The importance of automated guided vehicles is increasing in flexible manufacturing systems as they are flexibly to change in facilities and factory layouts. This study proposes a transport route that introduces a roundabout and a one-line through method based on the knowledge of transportation systems, to prevent interference between AGVs under irregular transport requirements and to achieve high transport efficiency. AGVs are required for irregular transportation, and stopping multiple AGVs. Due to interference between them during operation is a challenge that should be prevented because it will stop the production line and reduce production efficiency. The locations where speed differences occur are where the AGVs receive and deliver the materials to be transported. We will apply the knowledge of traffic engineering to improve the efficiency of transportation, and also adopt indices obtained from the knowledge of traffic engineering to evaluate transport efficiency.
