Modify your solution to Exercise 5-2 to use Sequences to control the f ow of parts through the system. Also add a transfer time between arrival and the f rst machine, between both machines, and between the last machine and the system exit that follows a triangular distribution with parameters 7, 9, 14 (minutes). View this as a terminating simulation, and make 100 replications of this model as well as the one from Exercise 5-2, using PAN to compare the results for average total time in system and the average lengths of each queue.
