1. Explain why system indenture levels are important when choosing where to begin a FMEA. Provide an example that illustrates your point (other than the example in the course textbook).
Your response must be at least 75 words in length.
2. What does the fault tree in Figure 7.6 of the course textbook (p. 77) tell you about strategies for extinguishing a fire?
Your response must be at least 75 words in length.
3. Consider a fault tree with an AND gate under the top event. The first tier contains four failure events with respective failure probabilities of 0.005, 0.002, 0.01, and 0.0001.
A.What equation should you use to compute the probability of the top event?
b. Using the equation, what numerical value do you get for the top event probability?
c. For the top event, what is the probability of the complimentary event (i.e., success probability)?
4. Explain why common-cause failure analysis is important when dealing with redundant systems. Provide an example that illustrates your point (other than one from the course textbook).
Your response must be at least 75 words in length.
5. Identify the two logic gates commonly used in fault tree analysis, and briefly explain the difference.
Your response must be at least 75 words in length.
6. Consider the three methods of fault tree analysis discussed in Chapter 8. Compare and contrast the advantages and disadvantages of these methods.
Your response must be at least 200 words in length.
7. Discuss reasons why a safety practitioner might want to use quantitative analysis of risks rather than a simpler qualitative analysis. Provide examples that illustrate your point.
Your response must be at least 200 words in length.
