1) at a manufacturing facility, a worker processes one job at a time from a queue of jobs. IF there are three jobs in the queue with an expected processing time of 5, 2, and 12 minutes, what service discipline should be adopted by the worker? A) first-in-first-out b) last-in-first-out c) shortest processing time first d) longest processing time first 2) customer arrival at an ATM facility follows Poisson distribution with a mean arrival rate of 4 customers per minute. The average service time at the ATM facility is exponentially distributed with a mean of 40 seconds per customer. What is the minimum number of ATM kiosks needed for the system to be in equilibrium? A) 1 kiosk
