Of the four entity types, only one needs to be scheduled to arrive in the system. Every 45 minutes one Pallet arrives at the Receiving location. The word "INFINITE" in the Occurrences column means that one pallet continues to arrive every 30 minutes as long as the simulation runs. For more information on defining arrivals, see Arrivals.
