The operator-machine interaction in a workshop is summarized in the steps below. Is it more economic to assign a worker to service: a) 2 machines; or b) 3 machines, given that the operator earns $12/hr and the machine costs $18/hr to operate.
(a) Machining time = 2.0 min, (b) Loading time = 0.2 min, (c) Unloading time = 0.2 min, (d) travel time = 0.5 min
1) Serving 2 machines
2) Serving 3 machines
Additional information:
The problem related to Mathematics and it explains about calculation of optimum operator-machine interaction time.
