IQRAS

iQRAS is a user friendly software tool with a fully integrated environment for constructing and analyzing risk models. A powerful aid for conducting PRA, you can construct and quantify risk scenario models, estimate numerical risk levels, and identify major risk contributors... On the computational side, iQRAS offers state-of-the-art algorithms that are both highly efficient and, unlike conventional solution methods used in most other tools, are not subject to often significant approximation errors.
