Abatch of parts is produced on a semi-automated production machine in a sequential batch production operation. batch quantity is 300 units. setup takes 55 min. a worker loads and unloads the machine each cycle, which takes 0.75 min. machine processing time is 3.46 min/cycle, and tool handling time is negligible. one part is produced each cycle. determine (a) average cycle time, (b) time to complete the batch, and (c) average production rate.
