The Copier Line - an exercise in comparative modeling

Currently people arrive (and exit) through two different doors to wait in one line to use a single copier. They arrive through each door at a rate of 1 person every two minutes, i.e an overall arrival  rate of one person each minute. The mean self service time on the machine is 1 minute with a standard deviation of .25 minute.

Using the tool you are assigned, create a mathematical and visual simulation of this environment.

Using the simulator, determine the service time necessary to move the line into a steady state.
