The local Department of Motor Vehicles issues new licenses and renews licenses. (See the diagram below.) 75% 15% 15% Reception Eye test Exit Issue license Exit 85% 10% 90% Written test Exit 10% The office receives 110 customers per hour. All customers first see a receptionist. The receptionist directs them in one of three directions. 75 percent go directly to Issue License (staffed by 9 workers) where a new photo and license are done. 15 percent are required to take an eye test (staffed by one worker), and 10 percent must first take a multiple-choice electronic written test (on one of three computers). Only 85 percent of people pass the eye test and the remaining 15 percent exit. The customers who pass the eye test proceed on to the written test. 10 percent of the people who take the written test fail it, while 90 percent pass the test and then proceed to Issue License. The processing times of the stations are listed in the following table. Station Number of workers Processing time (minutes) Reception 1 0.4 Eye test Written test 3 15 Issue License 9 1 5 6 1.

Given bottleneck constraint, how many people per hour come out of DMV with a license with current staffing 5. How many employees, and where, should we add to process the 110 people per hour Hint 1: draw the process and plot the numbers Hint 2 : time to open xls
