Question
Scenario E.1
SimQuick is being used to simulate the following bank process:
Entrance
Door
Buffer
Line
Work Station
Teller
Buffer
Served
Customers
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:
