1. You are evaluating a potential work cell setup. It is a mill operation that runs for 15 minutes. The operator spends 21/2 minutes removing the finished part and putting a new piece in the fixture. The worker is paid $15/hr. You have estimated that the worker would spend 45 seconds traveling from one machine to another. The accountants predict that each mill will cost $25/hr to run. Based on lowest cost, how many machines should you use in your cell if you only use the one worker? What would happen to the cost if you reduced setup time by 30 seconds? [Show all of your work]
