Abstract
In this paper, investigations are carried out to evaluate the performance of dynamic job selection dispatching rules for simultaneous dispatching and scheduling of multi-load automated guided vehicles (AGVs) cruising in two different sizes of FMS. Two multi-load AGVs cruise according to machine initiated nearest vehicle (NV) dispatching rule to pick and drop materials in the reported flexible manufacturing system (FMS). Two sizes of FMS facility was considered for performance evaluation of five types of dynamic job selection dispatching rules. The dynamic job selection dispatching rules applied in FMS were evaluated by simulation experiment. Investigations revealed that the job selection dispatching rule having selection criterion based on the destination similarity between jobs outperforms all other dispatching rules. Further, it was also found that AGV speed and AGVs fleet size has a significant role in increase or decrease of throughput of the FMS.
