In Exercise 6-15, suppose you could hire a total of f ve more people (rather than just one more) to be allocated in any way to the existing staff at manual check-in, automated check-in, or security. You can’t reduce staff ng anywhere from the levels in Exercise 4-22. Using average total time in system of all types of passengers combined, what would be the best deployment of these f ve additional people? Should you even use all f ve of them? Set up an OptQuest run and decide about the stopping criterion and numbers of replications.
