Fault tree analysis (FTA)

Trace back to basic causes

Industrial Risks menu → 7. Fault tree analysis

Build a graphical fault tree with AND/OR logic gates and automatic probability and minimal-cut-set calculations using MOCUS.

What you will do

  1. Drag events and logic gates from the palette.
  2. Connect basic events to the top event through the gates.
  3. Review automatically calculated minimal cut sets; they identify the shortest combinations of failures to address.

Pitfall to avoid. An edge that creates a graph cycle has no physical meaning and would cause an endless calculation. The tool blocks it by design.
