Theoretical Analysis of the Information Received Area for a Decentralized AGV System

Abstract

Recently, some attempts have been made to decentralize vehicle movement control for AGV systems. However, some communication problem may deteriorate the efficiency of the vehicle movement under the protocol similar to the centralized control. Thus, we impose some restriction on the information received area of each vehicle. In this paper, we theoretically analyze the information received area which is necessary and sufficient for each vehicle to reach its destination in finite time. We also clarify necessary and sufficient conditions for the vehicle with the highest priority to continue onward movement.
