Continuing Problem 50, you might expect that the system will be only as good as the station with the smallest value of si μi (called the bottleneck station). This problem asks you to experiment with the simulation to gain some insights into bottlenecks. For each of the following parts, assume a Poisson arrival rate of   1 per minute, and assume that processing times are exponentially distributed. Each station has si  1 and there are five stations. Each station, except for the bottleneck station, has a processing time mean of 1μi 

0.6 minute. The bottleneck station has mean 0.9 minute. Each part should be answered independently.

For each, you should discuss the most important outputs from your simulation.
