Abstract System reliability sensitivity analysis becomes difficult due to involving the issues of the correlation between failure modes whether using analytic method or numerical simulation methods. A fast conditional reduction
method based on conditional probability theory is proposed to solve the
sensitivity analysis based on the approximate analytic method. The relevant
concepts are introduced to characterize the correlation between failure modes
by the reliability index and correlation coefficient, and conditional normal
fractile the for the multi-dimensional conditional failure analysis is proposed
based on the two-dimensional normal distribution function. Thus the calculation of system failure probability can be represented as a summation… More >
