In Example 2.7, suppose an operator is assigned three machines, the work shift begins at 8:00 A.M., a 15-minute break occurs at 9:45 A.M., a 30-minute lunch break occurs at 11:45 A.M., a 15-minute break occurs at 2:00 P.M., and the shift ends at 4:00 P.M. When breaks occur, all machines are stopped. Parts cannot be partially machined when machines are stopped. Hence, transient conditions exist when machines are started and when machines are stopped. How many parts are produced per shift? Under steadystate conditions, how many parts would be produced during an eight-hour period?
