Example: Peter’s Drive-In on 16th
Avenue has one walk-up service window for people who want to park their cars
and eat at a picnic table. On the Friday before a long weekend, customers
arrive at the window at a rate of 30 per hour, following a Poisson
distribution. There is a very large, almost infinite number of hungry customers
at this time of the year. The customers are served on a first come, first
served basis, and it takes approximately 1.5 minutes to serve each customer.
