Exercise 40

Taguchi Loss Function Analysis (Appendix) Duramold specializes in manufacturing molded pla tic panels to be fitted on car doors. The blueprint specification for the thickness of a high-demai model calls for 0.1875 ± 0.0025 inch. It costs $120 to manufacture and $150 to scrap a part that do not meet these specifications. The thickness measure for the unit just completed is 0.1893 inch.

Required

1. Use the Taguchi Loss Function, L(x), to determine:

a. The value of the cost coefficient, k

b. The amount of loss for the unit, L(x = 0.1893)

---

2. Assume that Duramold can eliminate the uneven thickness by adding a production worker, at the critic

production point, for $6 per unit. Under this assumption:

a. At what tolerance should the panels be manufactured? Show calculations.

b. What should be the production specification for these panels?

Step 1 of 5

The formula for value of coefficient k is as follows:
