The quality-control staff for the fan-assembly area of Exercise 5-5, has decided that if a fan is rejected a second time it should be rejected from the system and sent to a different area (outside the boundaries of this model) for rework. Make the necessary changes to the model and run the simulation for 20,000 minutes and compare the results (based on just one replication of each model). Also keep track of the number of fans rejected from the system.
