Using the model from Exercise 7-2, change the processing time for the second pass on Machine 1 to TRIA(6.7, 9.1, 13.6) using Sequences to control the f ow of parts through the system and the assignment of process times at each machine. Run the simulation for 20,000 minutes. To the extent possible, indicate the batch-means-based conf dence intervals on expected steady-state performance measures from this run.
