Question 1 (50 marks). Modify Model 3-] with all of the following changes: Add a second machine (washer) to which all parts go immediately after exiting the rst machine [drill press] for washing. Processing times at the washer are independent of those from the drill press but drawn from the same distribution as for the drill press. Gather all the statistics as before, plus the time in queue, queue length, and utilization at the washer. Immediately after the washer, there is a pass/fail inspection that takes a constant 4.5 minutes to carry out and has an 75% chance of a passing result; queuing is possible for the single inspector, and the queue is rstin rstout. The parts that fail inspection after being washed are sent back and re-washed. Such rc-washcd parts must then undergo the same inspection, and have the same probability of failing. There's no limit on how many times a. given part might have to loop back through the washer and inspector. Gather statistics on the time in queueI queue length, and utilization at the insiiection center. Include plots to track the queue length and number busy at all three stations; put all queue lengths together in the same plot, and put all numbers busy in the same plot [you will need to turn on the plot Legends to identify the three curves}. Congure them as needed. Run the simulation for 480 minutes instead of 20 minutes
