Apply techniques like Fault Tree Analysis (FTA) or Event Tree Analysis (ETA).
A comprehensive CPQRA relies on a systematic, data-driven workflow. Skipping any of these steps invalidates the mathematical model.
This is the core calculation step where Consequence and Frequency are combined.
Gather Piping and Instrumentation Diagrams (P&IDs), Process Flow Diagrams (PFDs), meteorological data, population densities, and equipment failure rate databases. Phase 3: Software Selection
