A ow line has three servers in series, each of which use FIFO. The rst server has a capacity of 3 with triangular(5, 7, 9) service times. The second has a capacity of 1 with triangular(l, 2, 5) service times. The third server has capacity 4 with triangular (4, 8, 12) service times. Arrivals to the rst server are exponential(3). There is no travel time between servers. Create a Simio model of this system. Conduct 25 replications of system operation, each lasting 72 hours. Service times are in minutes. a. (10) What are the average total time in system and the average total number in system? What are the average queue lengths for each server? What is the utilization of each server? b. (10) Increase the capacity at server 2 to 2 and rerun the replications. Which server now has the largest average queue length
