Brief Notes #9 CALCULATION OF RELIABILITY INDEX, β ) I , 0 ( ~ Z ) , m ( ~ X Σ 1. Select initial unit vector, o α 2. Find o o * o z α β = where { } F o o D : min α β β = β 3. Linearize Β around * o z Let o γ be the unit external vector: * o z o ) z ( g grad ) z ( g grad = γ * o z i z ) z ( g # 4. Go back to step 2 with o α replaced with o 1 γ = α . Iterate until convergence in β and * z. 1. Select initial unit vector, o α 2. Find Β
