Build a structured hierarchy of your system: Systems, Equipment, Functions, and Failure Modes. Capture effects, severity, occurrence, and detection ratings with automatic RPN calculation.
Top-down deductive analysis showing how component failures lead to system-level events. Visual editor with drag-and-drop gate construction and full quantitative analysis.
Model system structure as interconnected blocks in series, parallel, or k-of-n configurations. Calculate system-level reliability, availability, and failure frequency.
Understanding what can fail — and how likely it is — is the foundation of every reliability programme. Without structured failure analysis, organisations rely on assumptions. With RaCom's FTA/RBD Module, every risk is identified, modelled, and quantified.
Access anywhere. No installation. Just open your web browser, login, and go.
Drag-and-drop construction of fault trees with automatic layout. Add gates (OR, AND, VOTE), intermediate events, and basic events. Zoom, pan, and navigate complex trees with ease.
Build reliability block diagrams with series, parallel, and k-of-n configurations. Visual connection of blocks with automatic routing. System-level metrics calculated instantly.
Full FMEA worksheet with tree view navigation and tabular editing. Severity, Occurrence, and Detection scoring with automatic RPN calculation and colour-coded risk levels.
Shared library of component failure data used across all analyses. Standard failure rates from industry databases. Build your own library from operational experience.
Generate fault trees and block diagrams directly from the FMEA with correct gate types and failure data. Equipment gate types (OR, AND, VOTE) map directly to analysis structures.
Component-level reliability prediction using MIL-HDBK-217F and Telcordia methodologies. Calculate base failure rates adjusted for environmental and operating conditions.
Branded PDF reports for every analysis type: FMEA worksheets, fault tree diagrams with results, block diagram summaries. Ready for client review or regulatory submission.
Every analysis result includes a plain English explanation alongside the numbers. Understand what the results mean without needing deep specialist knowledge of reliability theory.
Probability of system failure over a defined mission time. Understand how likely the system is to fail during the period that matters.
Steady-state probability that the system is down at any given time. Essential for availability targets and SLA compliance.
Expected number of system failures per unit time. Directly feeds maintenance planning and spare parts provisioning.
Plus: minimal cut sets, importance measures, sensitivity analysis, and multiple failure distribution support (Exponential, Weibull, Lognormal, Normal).
The FTA/RBD Module works as a powerful standalone tool. But it also integrates seamlessly with the RCM Module and RDT DRACAS to form a complete reliability lifecycle. Export your FMEA hierarchy directly to RCM for maintenance optimisation, or to RDT for operational failure tracking.
Define your system once. Use it everywhere. No re-keying, no inconsistency.
We'd love to show you how RaCom handles failure analysis, fault trees, and block diagrams in a single integrated workflow.
