Question: Multi-stage Queues Consider the following two-station process (with exponentially distributed interarrival and service times). Workstation (= 1 consists of a single server with a capacity

Multi-stage Queues Consider the following two-station process (with exponentially distributed interarrival and service times). Workstation (= 1 consists of a single server with a capacity of 42 jobs per hour. The arrivals of jobs from the previous process averages 35 parts per hour. Finally, after the parts leave the first workstation, they pass to workstation = 2 consisting of a single server with a capacity of40 jobs per hour. 14. What are the utilization factors for each workstation (that is, p1 andpa)? (2 pts) 15. What is the total queue time for a job? (Hint: first calculatela 1andLg usingpuandpafrom above, then derive Wateta=Wq 1+W42.) (2 pts) 160/hich workstation should get an additional server (in the form of one M/M/2 queue) if you want to minimize total queue time? What is the new total queue time for a job if this server. were to be added? (2 pts
