This research is concerned about a case study for determining the required number of resources such as workers and material handling devices, which handle materials in warehouse system. To validate the possibility of efficient logistics operation in warehouse system even under daily maximum product shipment, simulations with animation are performed and the results are analyzed. In determining a dynamic and complex system specification, the status of workers and the other physical facilities are considered through system analysis. The system parameters, which have an important impact on warehouse system performance, are chosen to study their effects. Then, the best condition for the daily maximum product shipment in warehouse system is selected by comparing the simulation results.
