Abstract: The automatic guided vehicle system (AGVs) is an important element for material handling facility in the computer integrated manufacturing. The essential capability of an AGV is the ability to transfer loads to remote locations or through complex paths under computer control. They are used to move jobs between work stations on a factory floor. Research in this area is directed towards the development of a path layout design and routing algorithms for vehicle movement and control. The problem is to design a path layout and a routing algorithm minimising the distance travelled by AGVs considering sufficient but necessary conditions. Split loads concept is implemented for material handling for effective utilisation of AGVs. The capacity utilisation is analysed in terms of the distance travelled and the time required for AGVs to complete all pickup and drop-off jobs. Numerical results are presented to compare performance of the proposed model.

Keywords: automated guided vehicles; AGVs; split loads; network modelling; materials handling; dispatching; path layout; routing; capacity utilisation.
