Quizplus · Accepted Answer

The system utilization factor is calculated as the arrival rate divided by the total service rate. With 5 servers, the total service rate is 5 * 0.4 = 2 customers per minute. The arrival rate is 1 customer per minute. Thus, the utilization factor is 1 / 2 = 0.5. However, the correct choice should be 0.8, indicating a mistake in the problem setup or choices.
