As automation levels increase, the number of labor hours required to produce each unit falls.

For each point of change in automation, up or down, the company is charged $4.00 per unit of capacity. For example, if a line has a capacity of 1,000,000 units, the cost of changing the automation level from 5.0 to 6.0 would be $4,000,000.

When you buy automation, you might want to determine the return on investment (ROI). Your labor cost savings be approximately 10% for each new point of automation. Multiply the savings by the number of rounds remaining in your simulation then divide it by the total cost of the automation. (Savings * Remaining Rounds) / Automation Cost = ROI

Calculate the ROI for each product line below.
