Are Probabilistic and Anti-Optimization Approaches Compatible?

This study is directed to a single objective: to illustrate the possible error associated with the effect of a small perturbation in the probability density on the structural reliability. This perturbation is associated with interpretation of the experimental data, which lies as a basis of the probabilistic model involved. Moreover, the small perturbation in the probability density is still associated with the same probabilistic moments possessed by an unperturbed density. It appears that the analysis of a possible error must become a part of a meaningful probabilistic analysis.
