Calculate Lead Time Flint Fabricators Inc. machines metal parts for the automotive industry. Under the traditional manufacturing approach, the parts are machined through two processes miling and finishing Parts are produced in batch sizes of 90 parts. A part requires 5 minutes in miling and 10 minutes in finishing. The move time between the two operations for a complete batch is 11 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 yze 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.
