Subspecies of Simulation. Whilst simulation combines the decision making process and the material flow within one model, the emulation uses the simulation model of the material flow and uses the real Terminal Operating System (TOS) to control the processes within the material flow.
Thus the simulation model provides a test-bed for the real control system. It may be used for functional testing, strategy optimisation and training of the control staff."
