Question

Taguchi Loss Function

Stahman, Inc., estimates its hidden external failure costs using the Taguchi loss function. Stahlman produces plastic sheets that vary in thickness and grade. For one of its large-volume products, it was determined that k = $40,000 and T = 0.29 inches in diameter. A sample of four units produced the following values:

Required:

1. Calculate the average loss per unit. Round your intermediate calculations to six decimal places. If required, round your answer to the nearest cent and use the same in subsequent requirements.
$ per unit

2. Assuming that 140,000 units were produced, what is the total hidden cost?

$

3. Assume that the multiplier for Stahman’s hidden external failure costs is six. What are the measured external costs?

$

Unit No. Actual Diameter (y) 1 0.29 2 0.31 3 0.27 4 0.30

Explanation / Answer

PART 1

( y - m ) 2

PART 2

Total units produced = 140000

So, total hidden cost = 140000 x $9 = $ 1260000

PART 3

( y - m ) 2

Unit Actual Diamter(y) m y-m

( y - m ) 2

Loss = k * ( y - m ) 2 1 0.29 0.29 0 0 0 2 0.31 0.29 0.02 0.0004 16 3 0.27 0.29 -0.02 0.0004 16 4 0.30 0.29 -0.01 0.0001 4 Total Loss $ 36 Avg Loss $ 9
