Production time per day is 420 minutes, and the assembly steps and times for the wagon are given in the following Exhibit. Assignment: find the balance that minimizes the number of workstations, subject to cycle time and precedence constraints.
Question
A company is considering adding a new feature that will increase unit sales by 6 percent and product cost by 10 percent.  Profit is expected to increase by 16 percent of the increased sales.  Initially the product cost incurred by the company was 63 percent of the sales price.  Should be the feature be added?
Let the sales be $100M.
Solution
Day 1
Problem 1
Sales increase by 6% = $100M x 6% = $6M
 Benefits: Profits increase by 16% of the increased sales = $6M x 16% = $0.96M
 Cost: Increase product cost by 10% = ($100M x 63%) x 10% = $6.3M
Because costs exceed benefits, the new feature should not be added.
