3. Reliability analysis products
The preceding paragraphs have shown how to calculate the probability of failure and the reliability index. The results obtained provide reliability information that depends on the quality of the mechanical and stochastic models used. This paragraph shows that other information can also be used by the designer.
3.1 Factors of importance
Importance factors are quantities that express the variation of the reliability index or probability of failure with respect to design parameters. Consider a quantity Q ({x }) of variables {x } :
a sensitivity factor is the derivative (gradient) ...

Software tools
Structural Safety 28 (2006) has published a special issue summarizing 10 software packages available worldwide for stochastic calculation. Each software package is presented, and an illustration shows what can be expected from it for significant industrial applications. It should be noted that the "out-of-the-lab" offer is still limited to mechano-fiabilistic coupling using FORM/SORM methods, direct and conditioned Monte-Carlo...
