ENGINEERING COSTS AND COST ESTIMATING

MULTIPLE CHOICE

1. A television assembly plant has a variable production output ranging from 200 sets to 350 sets a day. The building for both manufacturing and warehousing has an area of 80,000 square feet. It employs about 250 people. Most of the components that go into the assembly are also produced in the plant.

An example for fixed cost in this plant is ______________.

A. Equipment cost

B. Power cost

C. Labor cost

D. Material cost

Answer: A.

Feedback: Equipment cost stays the same regardless the level of production output once the plant has been designed to produce at a certain level.

2. An example for variable cost in a typical manufacturing plant is ______________.

A. Building cost

B. Equipment cost.

C. Labor cost.

D. Property taxes

Answer: C

Feedback: Labor cost depends on the output level.

3. The first unit produced in a plant took about 10 hours. If the learning curve is 95%, the time required to produce the 8th unit may be estimated to be ________.

A. 8 hours.

B. 8.57 hours

C. 6.30 hours

D. 7.6 hours

Answer: B

Feedback:

T8 = T1 (8)b

b = log 0.95/log 2 = -0.074

T8 = 10 (8) -0.074 = 8.57

4. If the time required for the first and eighth units are 7.29 hours and 10 hours respectively in a production operation determine the learning curve percentage for this operation.

A. 72.9%

B. 95%

C. 81%

D. 90%

Answer: D

Feedback:

T8 = T1 (8)b

7.29 = 10 (8) b

b = -0.152

Log (X)/log 2 = -0.152

X= 90%

5. Given: Total fixed cost = $420. Variable cost/unit = $20 Revenue/unit = $30.

The breakeven volume is _____________.

A. 14

B. 21

C. 42

D. 32

Answer: C

Feedback:

Let the breakeven volume be “X”.

30 X = 420 + 20 X

10 X = 420

X = 42

6. Given: Total fixed cost = $420. Variable cost/unit = $20. Revenue/unit = $30.

Determine the profit that can be made for a volume of 50.

A. $80.

B. $500

C. $580

D. 420

Answer: A

Feedback: Profit for 50 units = 50(30) - {420 + 50(20)} = $80

7. At Kal Tech Manufacturing Inc, the time required to make the first unit of an engineered product is 45 minutes. Determine the time required for 16th unit if the learning curve percentage is 90%.

A. 36.45 minutes

B. 20.89 minutes

C. 42.1 minutes

D. 29.53 minutes

Answer: D

Feedback:

T16 = T1 (16)b

b = log 0.90/ log 2 = -0.152

T16 = 45 (16) -0.152 = 29.53
