The factors that are compared are the number of parts, which later needs to be assembled. The average product thicknesses enable to calculate the weight difference. The cutting and welding lengths are important to represent production time and costs. Finally, the proportion of bends as well as how long each bend should be needs to be compared.
Using these inputs, time and costs for each product can be compared. The higher material cost of the high-strength material can be motivated by enabling lower manufacturing time and costs.
