Scenario E.1 SimQuick is being used to simulate the following bank process: Entrance Buffer Work Station Teller Buffer Served Customers. Door Line 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 6.23 Objects unable to enter Service level 0.87 Buffer Line 37.83 Objects leaving Final inventory 3.98 Minimum inventory 0.00 5.85 Maximum inventory Mean inventory 3.08 Mean time in buffer 9.75 Work Station Teller 37.83 Work cycles started Fraction time working 0.94 Buffer Served Customers Final inventory 36.85 Use the information in Scenario E.1. Approximately what percentage of total customers who arrived during the 2-hour period found the buffer full and were not able to enter? 87% 13% 94% 6% Use the information in Scenario E.1. On average, approximately how many customers were waiting in line during the 2-hour simulation period? 4 3 O O 2
