In the hand simulation of the simple processing system, suppose the drill press can work on two parts simultaneously (and they enter, are processed, and leave the drill press independently). There’s no difference in processing speed if there are two parts in the drill press instead of one. Redef ne B ( t ) to be the number of parts in service at the drill press at time (so 0 # B ( t ) # 2), and the drill press utilization is redef ned as e0 T B(t)dt _______ 2T where T 5 20. Rerun the original simulation to measure the effect of this change.
