- Abstract Automated Guided Vehicles (AGV) are commonly used to transfer parts in flexible manufacturing systems (FMS). AGV dispatching deals with assigning vehicles to move parts based on the relationship between AGV and parts availability. The dispatching method influences the performance of the FMS and can lead to cost saving and improvement. The production environment is complex and the dispatching decision is sometimes vague and obscure. To deal with such complicated environments a fuzzy logic dispatching model has been developed.
