SCM Chapter 5

A philosophy and a set of planning and communication tools that focus on customer needs in coordinating the design, manufacturing, and delivery of goods & services is called what?

Quality function deployment

House of quality

Quantity function deployment

Traditional Goal Post View means that parts out side of the ideal specification are

Marked off as a complete loss if outside the specification range of variabliity

Calculated using a quadratic formula to find how much is a loss

Marked off as a complete loss, regardless of variablity

Suppose the specification of a part is .50 ± .02. A newly manufactured part measures at .55cm and the cost to repair is $45. Under the Traditional Goal Post View, what is the cost of the repair?

$50

$35

$40

$45

Suppose the specification of a part is .50 ± .02. A newly manufactured part measures at .55cm and the cost to repair is $45. What is the Taguchi loss function for the part?

L(x)=$125,000(x-T)^2

L(x)=$112,500(x-T)^2

L(x)=$2,250(x-T)^2

L(x)=$225,000(x-T)^2

Suppose the specification of a part is .20 ± .03. The constant is $150,000. What is the amount loss to replace the part?

9,000

125

135

4,500

Suppose the cost to replace a part is $50, the constant is $160,000, and the target spec is .25mm. What is the ideal deviation?

Assuming that the target value of a part is 2.50 cm, its Taguchi loss function is L(x) = $250,000(x – T)^2, and a simple adjustment can be made at the factory for only $100 to get this dimension very close to the target value. What is the specification of the product?

± .0008

± .0400

± .0200

± .0230

The specification of a part is 2.500 ± 0.050 cm, and L(x) = $500,000(x – T)^2. What is the loss if a unit produced is measured at 2.490 cm?

$55

$1,250

$45

$50

Assuming that the target value of a part is 0.60 cm, its Taguchi loss function is L(x) = $100,000(x – T)^2, and a simple adjustment can be made at the factory for only $10 to get this dimension very close to the target value. What is the specification of the product?
