Question

A specification for the length of an auto part at Adams Metal Fabricating is 15.0 ± 1.75 centimeters (cm). It costs $56 to scrap a part. Determine the Taguchi loss function. Then determine the expected loss if the process mean is found to be 15.03 cm with a variance of 0.49 cm2.

Answer 1

Ans:

Taguchi Loss Function:

Expected Loss:

Calculations are hand written:

Taguchi Loss Function:

L(x) = 18.29 ( x - T )²

Expected Loss = $8.98
