Recall the bank model of Sec. 2.6, and suppose that the bank’s management would like an estimate of the effect of adding a sixth teller and of adding a seventh teller (in comparison with the current configuration of five tellers) that is better than the results in Fig. 2.36. Use CRN to do this, and make enough replications of the three systems to obtain what you feel are sufficiently precise estimates of the differences in the expectations of the average delays in queue. Consider generating customer service times when the customer arrives, rather than when he or she enters service.
