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:

A satellite has two redundant control systems, each has a failure rate (lambda) = 1×10 -6 failures/hour. If one of the systems fails, the failure rate for the remaining system increases to 2×10 -5 failures/hour.
What is the reliability of the redundant control systems at 175,000 hours?

What is the probability of exactly 3 defects given the following?
- Probability of 1 or more defects = 0.75
- Probability of 2 or more defects = 0.41
- Probability of 3 or more defects = 0.17
- Probability of 4 or more defects = 0.05
Response:

Experimental design plans usually call for testing a number of factors and keeping all other conditions as nearly constant as possible.
Taguchi Methods call for similar techniques, but with a twist. Noise conditions are changes a bit to determine robustness. Where are the noise factors placed?
