Question 16

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:

Accepted Answer

A) 87%
