Question
I know 999 is correct. for the one answer i have filled in .
Calculate The elapsed time between starting a unit of product into the beginning of a process and its completion.Lead Time
Michigan Machining Company 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 90 parts. A part requires 3 minutes in milling and 8 minutes in finishing. The move time between the two operations for a complete batch is 9 minutes.
Under the lean manufacturing 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 6 parts and the move time is eliminated.
Determine the The time required to manufacture a unit of product or other output.value-added, The time that units wait in inventories, move unnecessarily, and wait during machine breakdowns.non-value-added, and total lead times, and the The ratio of the value-added lead time to the total lead time.value-added ratio under the traditional and lean manufacturing methods. If required, round percentages to one decimal place.
