A state driver's license exam center would like to examine its operation for potential improvement. Arriving customers enter the building and take a number to determine their place in line for the written exam, which is self administered by one of five electronic testers. The testing times are distributed as EXPO(8); all times are in minutes. Thirteen percent of the customers fail the test (it's a hard test with lots of questions). These customers are given a booklet on the state driving rules for further study and leave the system (on foot). The customers who pass the test select one of two photo booths where their picture is taken and the new license is issued. The photo booth times are distributed TRIA(2.6. 3.6, 4.3). The photo booths have separate lines, and the customers enter the line with the fewest number of customers waiting in queue, ignoring whether anyone is in service; if there is a tie, they enter the nearest booth, Booth 1. Note that this set of rules could lead to what might appear to be irrational customer behavior in the case that neither booth has a queue (i.e., the lengths of both queues are zero), Booth 1 is busy, and Booth 2 is idle-a customer coming into the photo area would choose to queue up for Booth 1 (via the tie- breaking rule, since the queue lengths are tied at zero) rather than go right into service at Booth 2-but hey, they can't see into the photo booths! These customers then leave the system (driving), proudly clutching their new licenses. The center is open for arriving customers eight hours a day, although the services are continued for an additional hour to accommodate the remaining customers. The customer arrival pattern varies over the day and is summarized below: Hour Arrivals per Hour Hour Arrivals per Hour 22 35 35 43 40 29 31 22 Run your simulation for ten days, keeping statistics on the average number of test failures per day, electronic-tester and photo-booth utilization (not utilization for the testing resource overall, but separate utilizations for each photo booth), average number in queue, and average customer system time for those customers passing the written exam. Animate all the electronic-test booths and the photo booths. Please, try 5 different scenarios with different statistics as changing with your assumptions. (Hint: If you think that there is some missing data, please fill with your assumptions.)
