I recently got interested in the theory of queues and the very unexpected results shown by analysis.. Suppose a small bank has only one teller. They are open 24 hrs per day, so three shifts operate. Customers take an average of 10 minutes to serve and they arrive at the rate of 5.8 per hour, ie on average about 10.35 minutes apart. What will the expected waiting time be? Does it reach a steady state, and how quickly? We assume customer arrivals -and customer service times- are random.
It turns out that on average customers will have to wait nearly five hours before they are served.
