Question:

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 52 units. The process time for each step is as follows:

Process Step 14minutes
Process Step 27minutes
Process Step 39minutes
Process Step 45minutes

The time required to move each batch between steps is 17 minutes. In addition, the time to move raw materials to Process Step 1 is also 17 minutes, and the time to move completed units from Process Step 4 to finished goods inventory is 17 minutes.

The new just-in-time layout will allow the company to reduce the batch sizes from 52 units to 3 units. The time required to move each batch between steps and the inventory locations will be reduced to 3 minutes. The processing time in each step will stay the same.

Required:

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

Value-added time_____ min_____ min
Non-value-added time_____ min_____ min
Total lead time_____ min_____ min
Value-added ratio (as a percent)_____ %_____ %

Non Value added lead time:
