The Boolean package comprises seven modules:
- BFiab: modeling via Reliability Block Diagrams (RBD),
- Tree: building fault trees,
- ETree: elaborating event trees,
- SIL: analyzing safety instrumented loops,
- Risk: conducting risk analyses via the bowtie or LOPA (Layer of Protection Analysis) method,
- Reseda: modeling reliability networks,
- Bool: combining all the features of Tree, ETree, SIL, Risk, Reseda and BFiab in a single module.
