In the results from Exercise 4-23, you might have noticed that AJ doesn’t have much to do. So say goodbye to him, and send salvaged parts to Brett for packing, along with the shipped parts. Both types of parts have the same priority for Brett, but they reside in separate queues. (HINT: It’s okay in Arena to have multiple places where entities are trying to seize on the same resource.) Compare the results to those obtained from Exercise 4-23. Put a text box in your Arena f le with the values for the average total time in system for Model 4-1, Exercise 4-23, and this exercise (just one replication of each).
