This repository includes generic models in OpenPSA XML format. The goals of including these models are to:

• Serve as test cases for various PRA tools, including Open-PRA.
• Familiarize users with different modeling approaches and formats.
• Provide a reference for PRA model exchange.
• And more.

The repository also maintains a schema for the models.

1. OpenPSA Model Exchange Format

The OpenPSA Model Exchange Format (MEF) represents about a decade of effort to develop a format independent of any specific quantification engine. The goal was to create a standard that researchers, corporations, and regulators could use collaboratively in an open environment.

2. Generation of Models

Models were gathered from SCRAM project.

3. Configuration of Models

Various models are available in different configurations.

4. Usage

These models can be used to test quantification engines. Additionally, they enable the creation of a verification platform between quantification engines, allowing developers or practitioners to cross-check their results. Moreover, these models serve as a foundation for benchmarking efforts for any quantification tool.
