SCRAM 0.16.2¶

SCRAM is a Command-line Risk Analysis Multi-tool developed by Olzhas Rakhimov.

SCRAM is a free and open source probabilistic risk analysis tool that supports the Open-PSA Model Exchange Format.

SCRAM is licensed under the GPLv3. The release notes, source code, and issue/bug tracker are located at GitHub.

SCRAM (Simple Command-line Risk Analysis Multi-tool) is a powerful, free, and open-source software designed to streamline and enhance probabilistic risk analysis (PRA). Built to support the Open-PSA Model Exchange Format (MEF), SCRAM offers unparalleled flexibility and scalability for professionals working in fields that require rigorous risk assessment, such as engineering, finance, and project management.

What is SCRAM?

SCRAM is a command-line tool that facilitates complex risk analysis by leveraging fault trees, event trees, and other probabilistic models. By utilizing the Open-PSA MEF standard, SCRAM ensures compatibility with a wide range of modeling software, making it an essential component of modern risk analysis workflows.
