Question 3(50%). In the hand simulation of the simple processing system, suppose that a constant setup time of 3 minutes was required once a part entered the drill press but before its service could actually begin. When a setup is going on, regard the drill press as being busy. Plot the total number of parts in system as a function of simulated time. Re-do the hand simulation and discuss the results. Some simulation records are given in the Excel file on Sheet Q3
