Question 46

The prediction technique has obviously not always been effective quantitatively. There is often a wide difference between actual reliability and predicted reliability. Nevertheless, the reliability prediction technique permits:
Response:
  • Question 47

    The hazard function is:
    I. The probability of failure during a very small time interval, assuming a failure occurs before that time.
    II. A function of constant failure rate only.
    III. A function of increasing failure rate only.
    IV. The ratio of the probability density function to the reliability function.

    Response:
  • Question 49

    Develop the fault tree analysis for a candy dispensing machine. There are two contributing subsystems, both of them must fail for the system to fail. The electronic release has Pf = 0.04 and the coil spring release has Pf = 0.06. What is the system's probability of failure?

  • Question 50

    Censoring of reliability data indicates which of the following?
    I. Biased product data is used.
    II. Testing has been failure terminated.
    III. The data collection is time limited.
    IV. Questionable data collection methods are used.
