In Exercise 5-5, suppose you could hire one more person and that person could be a second (identical) operator at any of the four locations. Which one should it be? Use PAN with 50 replications per scenario and select the best in terms of lowest average time in system. In retrospect, is your choice surprising? How critical is it to get this choice right? Now suppose you could hire up to three more people and allocate them any way you want to the four existing operators, including allocating all three of the new people to a single operator. What’s the best thing to do? Use OptQuest to search for the optimal allocation of this maximum of three more people, with the objective of minimizing the average time in system.
