Abstract

Abstract Bidirectional AGV systems are intuitively more attractive than unidirectional systems in terms of efficiency because of shorter travel distances. An efficient algorithm for finding conflict-free shortest-time routes for automated guided vehicles moving in a bidirectional flow path network has been proposed in a previous paper. This paper is a sequel and describes a conservative myopic strategy to coordinate the movements of vehicles in a bidirectional AGV system. Simulation results are presented to compare the performances of unidirectional and bidirectional systems.
