Design of Flowpath layout
Number and location of pick-up and delivery points
One of the main objectives of a control policy is to satisfy demands for transportation as fast as possible and without occurrence of conflicts among AGVs. Therefore, at least the following activities need to be performed by a controller of the system: • dispatching of loads to AGVs, • route selection, • scheduling of AGVs, • dispatching of AGVs to parking locations (i.e. locations where idle vehicles are positioned). Firstly, a vehicle is dispatched to a new transportation demand. The selected vehicle is assigned a route and schedule for the transportation task, such that the transport can be executed without occurrence of deadlocks and collisions. If no new jobs are available, an AGV can be routed to a parking location to wait for a new transportation demand.
