Scenario E.1 SimQuick is being used to simulate the following bank process: Customer arrivals at the Entrance Door of the bank with an average time between arrivals of 2.5 minutes. The Line Buffer holds 6 customers. If a customer arrives and the buffer line is filled, the customer leaves. The Work Station Teller's processing time per customer is normally distributed, with a mean of 3.0 minutes and a standard deviation of 0.5 minutes. The Served Customer Buffer in the flow chart is used to count the number of customers processed during the period simulated. A 2-hour period was simulated. The SimQuick simulation is run, and the results are as follows:

Element Types	Element Names	Statistics	Overall Means
Entrance	Door	Objects entering process	41.80
		Objects unable to enter	6.23
		Service level	0.87
Buffer	Line	Objects leaving	37.83
		Final inventory	3.98
		Minimum inventory	0.00
		Maximum inventory	5.85
		Mean inventory	3.08
		Mean time in buffer	9.75
Work Station	Teller	Work cycles started	37.83
		Fraction time working	0.94
Buffer	Served Customers	Final inventory	36.85
