Calculate The elapsed time between starting a unit of product into the beginning of a process and its completion.Lead Time

Orion Devices Inc. is considering a new just-in-time product cell. The present manufacturing approach produces a product in four separate steps. The production batch sizes are 49 units. The A sequence of activities linked together for performing a particular task.process time for each step is as follows:

Process Step 1	4	minutes
Process Step 2	7	minutes
Process Step 3	9	minutes
Process Step 4	5	minutes

The time required to move each batch between steps is 13 minutes. In addition, the time to move raw materials to Process Step 1 is also 13 minutes, and the time to move completed units from Process Step 4 to finished goods inventory is 13 minutes.

The new just-in-time layout will allow the company to reduce the batch sizes from 49 units to 3 units. The time required to move each batch between steps and the inventory locations will be reduced to 2 minutes. The processing time in each step will stay the same.

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, total lead times, and the The ratio of the value-added lead time to the total lead time.value-added ratio under the present and proposed production approaches. If required, round percentages to one decimal place.
