Although several analytical methods have been used to estimate the vehicle requirement for single-load AGVS, there are few reports on the same topic for multi-load vehicles. The dynamic behavior of multi-load vehicles whereby they can carry more than one job at a time makes fleet size estimation a complicated task. In this paper, an analytical method is proposed to estimate the number of multi-load vehicles needed to perform a given level of job handling in a job shop environment. Several methods for estimating the number of single-load vehicles are modified. Finally, simulation methodology is used to obtain the actual fleet size for an illustrative example under different vehicle dispatching rules. The results indicate that the proposed model can provide results that are close to the simulation results.
