A single server queuing system has an average service time of 16 minutes per customer,which is exponentially distributed.The manager is thinking of converting to a system with a constant service time of 16 minutes.The average arrival rate will remain the same.The effect will be to:
A)increase utilization.
B)decrease utilization.
C)increase the average waiting time.
D)decrease the average waiting time.
E)not have any effect since the service time is unchanged.
