Chapter 4 Problem # 13

Modify the model from Problem 1 assuming that you modeling a manufacturing process that involves drilling holes in a steel plate. The drilling machine has capacity for up to 3 parts at a time (c = 3 in queueing terms). The arrival rate should be 120 parts per hour and the processing rate should be 50 parts per hour. Use Good 3D Warehouse to find appropriate symbols for the entities. Add a label to your animation to show how many parts are being processed as the model runs.
