Question:
In Exercise 3-6, suppose that parts that fail inspection after being washed are sent back and re-washed, instead of leaving; such re-washed parts must then undergo the same inspection, and have the same probability of failing (as improbable as that might seem). There’s no limit on how many times a given part might have to loop back through the washer and inspector. Run this model under the same conditions as Exercise 3-6, and compare the results for the time in queue, queue length, and utilization at the inspection center. Of course, this time there’s no need to count the number of parts that fail and pass, since they all eventually pass (or do they?). You may have to allow for more room in some of the queue animations. Put a text box in your model comparing the same inspection-center results with those requested in Exercise 3-6. Do a paper-and-pencil, that is, no-simulation, analysis of what’s happening in the long run, that is, inf nite runlength, at both the inspection center and the washing center; f gure out the “effective” arrival rates to both of those places, and compare with their service rates—are your simulation results consistent with this? Maybe extend your simulation run as far past the 480 minutes as you can.
