QUESTION 1 Comparing a product or process against the best-in-class is known as benchmarking False QUESTION 2 Which of the following is a quantitative measure of reliability? @ a. Reliability bar O b. maintainability O c. mean time between failures (MTBF) o d mean time to repair (MTTR QUESTION 3 Extended producer responsibility (EPR) is a concept that holds companies responsible for their products even after its useful life True False QUESTION 4 The overall reliablity of the following system is 0.90 0.95 095 095 a greater than 1 00 o b 0.95 @ c. 0 90 o d 0 898

Explanation / Answer

1. True

This is benchmarking by its very definition.

2. c) Mean time between filures (MTBF)

MTBF is a measure of how reliable a component is.

3. True

EPR is a concept applied in waste management and holds producers responsible for its use as well as disposal.

4. c) 0.898

Reliability = 0.95 * (0.95+ 0.05*0.9) * 0.95 = 0.898

5. True

The design process begins with understanding the customer and identifying the customer needs. As they say, you cannot find a solution without first defining the problem.

6. d) Sustainability

This is sustainability by definition.

7. b) At least 0.896

We have, 0.99 * (0.95 + 0.05Rb) * 0.99 >= 0.975

Thus, Rb > 0.896

8. d) Reverse engineering

This is reverse engineering by definition

9. False

Modular design involves creation of unique products from multiple modules, which may or may not be standardized.

10. The question is unclear. The overall reliability is R1*R2, but individual values cannot be determined with the given information.

11. Please provide the complete question.

Availability = MTBF / (MTBF + MTTR)

12. d) 0.884

Overall reliability = 0.95 * 0.93 = 0.884

13. b)

Maximizing revisions is definitely not effective design. All other listed options are part of an effective design process.

14. False

New products are entering the market quicker and increasing overall competition in the market.

15. False

CAD significantly reduces the time to design better products.
