- 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.)
