Problem 8.3 John Doe has promised a total service time of 20 minutes. Processing time at the oven = 15 min Preparation = 2 min At most 3 minutes waiting time before the pizza has to be given away for free. Ri = 20 per hour. c = 5 ovens (each with a capacity of 60/15 = 4 pizzas /hr Rp = 20 no safety capacity. Any variability in arrival rate (or service time) will lead to a build up of queues and waiting time in excess of 3 minutes, resulting in John giving up many free pizzas. The potential partner should: a) get John to buy more ovens b) get out of the business c) stop giving the service guarantee.
