There are two types of simulations with respect to output analysis:
Runs for some duration of time $T_E$, where E is a specified event that stops the simulation.
Starts at time 0 under well-specified initial conditions.
Ends at the stopping time $T_E$.
Bank example: Opens at 8:30 am (time 0) with no customers present and 8 of the 11 teller working (initial conditions), and closes at 4:30 pm (Time $T_E$ = 480 minutes).
The simulation analyst chooses to consider it a terminating system because the object of interest is one day’s operation.
A non terminating simulation is one that executes continuously.
Runs continuously, or at least over a very long period of time.
Examples: assembly lines that shut down infrequently, telephone systems, hospital emergency rooms.
Study the steady-state (long-run) properties of the system, properties that are not influenced by the initial conditions of the model.
