5. Flo's Quick-Lube performs fast oil changes (A) and checks for tire pressure and wear (B) and
brakes and alignment (C) according to the process flow indicated by the diagram below. Each
incoming car is put on a jack while one technician performs task A and another simultaneously
performs task B and a third performs task C (which must follow task B due to the limited space
under the vehicle on the jack). The server for task A takes on average 3 minutes to process a job,
the server for task B takes on average 2 minutes to process a job, and the server for task C takes
on average 2 minutes to process a job. Server A can be operated in parallel with Servers B and C.
All processing times are random and exponentially distributed, and jobs are allowed to queue in
front of each server. (You can assume that the number of jacks is sufficient to allow any length of
queue.)
