Please, assists. thank you
Isaacson Dental Inc, is considering a new lean product cell. The present manufacturing approach produces a product in four separate steps. The production batch sizes are 50 units. The process time for each step is as follows: The time required to move each batch between steps is 6 minutes. In addition, the time to move raw materials to Process Step 1 is also 6 minutes, and the time to move completed units from Process Step 4 to finished goods inventory is 6 minutes. The new lean layout will allow the company to reduce the batch sizes from 50 units to 2 units, The time required to move each batch between steps and the inventory locations will be reduced to 1 minute. The processing time in each step will stay the same. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the (a) present and (b) proposed production approaches: If required, round percentages to one decimal place. Feestock * Chek My Wor In this exercise for Present: Value-added processing time = Add together Process steps 14 Non-value-added time = Total within-batch wait time + Move time, where Total Within-Batch Wait Time = (Total Time to Perform Operations) (Batch Size - 1) Add value-added processing time and non-value-added processing time to obtain total processing time. time to move completed units from Process . Step 4 to finished goods inventory is 6 minutes. The new lean layout will allow the company to reduce the batch sizes from 50 units to 2 units.

If required, round percentages to one decimal place. feedbach F Creck My Wis In this exercise for Present: Value-added procesing time = Add together Process steps 1+4 Non-yalue-added time = Total within-batch wait time + Move time, where Total Within-Bateh Wait Time = (Total Time to Perform Operations) x (Batch Add value-added processing time and non-value-added processing time to obtain total processing time. Calculate Value-Added Ratio = Value-Added Process Time + Total Process Time In this exercise for Proposed: Value-added processing time = Add together Proces5 steps 1+4 Non-value-added time = Total within-batch wait time + Move time, where Total Within-Bistch Wait Time is obtained by multiplying the process time by the remaining units in the batch (waiting their turn) Add value-added processing time and non-value-added processing time to obtain total processing time. C.elculate Value-Added Ratio = Value-Added Process Time + Total Process Time
