- __init__(threshold=0.0, mu1=120.0, sigma1=12.0, mu2=120.0, sigma2=12.0, mu3=120.0, sigma3=12.0, mu4=120.0, sigma4=12.0, mu5=50.0, sigma5=10.0, mu6=40.0, sigma6=8.0)¶
Creates a reliability problem RP8.
The event is {g(X) < threshold} where
X = (x1, x2, x3, x4, x5, x6)
g(X) = x1 + 2 * x2 + 2 * x3 + x4 - 5 * x5 - 5 * x6
- We have :
x1 ~ LogNormalMuSigma(mu1, sigma1)
x2 ~ LogNormalMuSigma(mu2, sigma2)
x3 ~ LogNormalMuSigma(mu3, sigma3)
x4 ~ LogNormalMuSigma(mu4, sigma4)
x5 ~ LogNormalMuSigma(mu5, sigma5)
x6 ~ LogNormalMuSigma(mu6, sigma6)
