A method for quantitative estimation of the reliability of a technical system for complex systems with a multiplicity of components. First, second and third failure rates are distinguished for the system components. An upper, lower and, if appropriate, mean value are in each case estimated for the largely unknown second failure rates by subjective expert opinion, and all upper, lower and, if appropriate, a mean probability distribution and, if appropriate, a mean probability distribution of the system reliability. Systematic correlations between expert estimates are thereby taken into account.
