alsdkhg;lskjg;lkjsl;gkajsdkl;fjdls;kjf;lakdsjfal;kdj 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: milling and finishing. Parts are produced in batch sizes of 45 parts. A part requires 6 minutes in milling and 8 minutes in finishing. The move time between the two operations for a complete batch is 5 minutes. Under the just-in-time 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 just-in-time manufacturing methods. If required, round percentages to one decimal place. Traditional Philosophy Just-in-Time Philosophy Value-added time min min Non-value-added time min min Total lead time min min Value-added ratio (as a percent) % % Hide Feedback Incorrect Check My Work Feedback Recall that lead time can be classified as one of the following:1. Value-added lead time, which is the time spent in converting raw materials into a finished unit of product2. Non-value-added lead time, which is the time spent while the unit of product is waiting to enter the next production process or is moved from one process to anotherIn this exercise for Traditional:Value-added processing time = Milling time + Finishing timeNon-value-added time = Total within-batch wait time + Move time, where Total Within-Batch Wait Time = (Total Time to Perform Operations) x (Batch Size - 1)Add value-added processing time + non-value-added processing time to obtain total processing time.Calculate Value-Added Ratio = Value-Added Process Time ÷ Total Process TimeIn this exercise for Just-In-time:Value-added processing time = Milling time + Finishing timeNon-value-added time = Total within-batch wait time, where Total Within-Batch Wait Time is obtained by multiplying the process time by the remaining units in the batch (waiting their turn)There is no move time.Add value-added processing time + non-value-added processing time to obtain total processing time.Calculate Value-Added Ratio = Value-Added Process Time ÷ Total Process Time
