- __init__(threshold=0.0, mu1=10.0, sigma1=0.5, mu2=0.0, sigma2=1.0, mu3=4.0, sigma3=1.0)¶
Creates a reliability problem RP77.
The event is {g(X) < threshold} where
X = (x1, x2, x3)
- if (x3 <= 5.0):
g(x1, x2, x3) = x1 - x2 - x3
- else :
g(x1, x2, x3) = x3 - x2
- We have :
x1 ~ Normal(mu1, sigma1)
x2 ~ Normal(mu2, sigma2)
x3 ~ Normal(mu3, sigma3)
- Parameters:
- thresholdfloat
The threshold.
- mu1float
The mean of the X1 gaussian distribution.
- sigma1float
The standard deviation of the X1 gaussian distribution.
- mu2float
The mean of the X2 gaussian distribution.
- sigma2float
The standard deviation of the X2 gaussian distribution.
- mu3float
The mean of the X3 gaussian distribution.
- sigma3float
The standard deviation of the X3 gaussian distribution.
- computeBeta()¶
Return the beta of the reliability problem.
This is the quantile of the probability of a standard gaussian distribution.
- Parameters:
- None.
- Returns:
- beta: float
The beta of the problem.
- getEvent()¶
Return the event.
- Parameters:

- getName()¶
Return the name of the problem.
- Parameters:
- None.
- Returns:
- name: str
The name of the problem.
- getProbability()¶
Return the probability.
- Parameters:
- None.
- Returns:
- probability: float
The probability of the event.
- toFullString()¶
Convert the object into a string, with full details.
- Parameters:
- None.
- Returns:
- s: str
The string of the problem.
