This problem asks you to experiment with the simulation to gain some insights into congestion.

For each of the following parts, assume a Poisson arrival rate of   1 per minute, and assume that processing times are exponentially distributed. Each part should be answered independently. For each, you should discuss the most important outputs from your simulation.

a. Each station has si  1 and the μis are constant from station to station. There are 100 (essentially unlimited) buffers in front of all stations after station
