Compute Lead Time
Jackson Fabricators Inc. machines metal parts for the automotive industry. Under the traditional manufacturing approach, the parts are machined through two processes: milling and finishing. Parts are produced in batch sizes of parts. A part requires minutes in milling and minutes in finishing. The move time between the two operations for a complete batch is minutes.
Under the lean philosophy, the part is produced in a cell that includes both the milling and finishing operations. The operating time is unchanged; however, the batch size is reduced to parts and the move time is eliminated.
Determine the valueadded, nonvalueadded, and total lead times, and the valueadded ratio under the traditional and lean manufacturing methods. If required, round percentages to one decimal place.
