Compute Lesid Time Bhojraj Fabricators Inc, machines metai 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 75 parts. A part requires 5 minutes in milling and 10 minutes in finishing. The move time between the two operations for a complete batch is 11 minutes. Under the tean 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 4 parts and the move time is eliminated. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the traditional and lean manufacturing methods. If required, round percentages to one decimal place
