hojraj Fabricators Inc. machines metal parts for the automotive industry. Under the traditional manufacturing approach, the parts are machined through two processes: alling and finishing. Parts are produced in batch sizes of 90 parts. A part requires 4 minutes in milling and 6 minutes in finishing. The move time between the two perations for a complete batch is 7 minutes. Jnder 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 s reduced to 5 parts and the move time is eliminated. Setermine 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
