Steel Inc.specializes in manufacturing ship doors.The blueprint specification for the thickness of a high-demand model calls for 0.9 $\pm$ 0.005 inch.It costs $800 to scrap a part that is outside of the specification.The thickness measure for the unit just completed is 0.85.
Required:
(1)Calculate the value of k,the cost coefficient in the Taguchi loss function.
(2)Calculate the estimated amount of loss for the unit,L(x)= 0.85.

Feedback: (1)k = Total quality cost/(Tolerance allowed)² = $800/0.005²= $180/0.000025 = $32,000,000 (2)L(0.85)= k(x - T)²;therefore,L(0.85)= $32,000,000 * (0.85 - 0.9)2= $80,000
