In the hand simulation of the simple processing system, suppose that the queue discipline were changed so that when the drill press becomes idle and finds parts wait$-$ ing in queue, instead of taking the first one, it instead takes the one that will require the shortest processing time $($this is sometimes called an SPT queue discipline$).$ To make this work, youll need to assign a second attribute to parts in the system when they arrive, representing what their service time at the drill press will be$.$ Redo the hand sim$-$ ulation. Is this a better rule? From what perspective?
