Abstract
Automated Guided Vehicle System (AGVS) become more and more significant industrial and scientific applications. Also, these AGVs can be applied to public area using service robots like office and hospital. Since the task assignment problem occurs and the task assignment method of AGVs affects a performance of AGVS, operation strategies of AGVs is very important. In this paper proposed between AGV and station for on-line and decentralized dispatching which improves a performance of AGVs. The protocol is modeled by Petri net to check resource conflict and deadlock problem. In order to conform the feasibility of the proposed protocol, the computer simulation is carried out.
