Safety Architect

Automatically generate the fault trees for your complex systems

Safety Architect is a tool achieving risk analysis of complex systems using functional or physical architectures from usual modeling tools, for example SysML or UML based tools. From a functional or physical definition of the system, Safety Architect allows to perform a kind of local FMECA and automatically deducts the FTA corresponding to the identified feared events.


Compliant with all the engineering loops
Focus on added value tasks
Enlighten the critical components and flows
Integrate safety analysis and design of your systems
Reduce the analysis cost and decrease the risk of errors
Capitalise on your analysis results for further iterations

Models import

Import the information from your existing system models to be able to easily start your safety analysis. Projects coming from usual modelling tools like MagicDraw, Rhapsody or Papyrus can be directly imported. A deeper integration is also available for Rational System Architect (RSA) and Capella, allowing to reexport the safety data created in Safety Architect to the system representation.

Methodological guide

Take in hands easily the concepts and the analysis processus recommanded in Safety Architect by following the proposed steps: from the feared events creation to the system failures global propagation. At each step, the related activities and diagrams are directly accessibles.

Graphical analysis

Create the graphical representation of your system or reuse the representation of your imported model. Safety analysis can then be performed locally to each block of your system, using a dedicated graphical representation, corresponding to the block dysfunctional behavior. This step allows to particularly considers the safety barriers or the block failure effects.

Automatic global propagation

Launch an automatic and global propagation of the failures in your system. Using the feared events which are identified and located on your system outputs and the local analysis of each block, this step consists in spreading in the system all the identified failure modes, to trace those (or combinations of them) that reach a feared event and generate automatically the related fault trees. Moreover, if the probabilities have been set on the failure modes or events, they are preserved in the fault trees, to be exploited in dedicated tools after an export.

Reports and fault trees

Generate automatically exhaustive reports of your analysis and export them as PDF or Word document to share your results easily. Create also the fault trees corresponding to your analysis and export them to external tools, like FaultTree+ or any other tools capable to read OpenPSA format, like ArbreAnalyste.

Monitoring and metrics

Follow the progress of your analysis in real time thanks to dedicated metrics. Visualise the blocks local analysis status per viewpoint, while keeping an eye on the representation of what is still to be done to achieve your system analysis.

They believe in Safety Architect

Safety Architect has been used for several projects in various domains, such as defense, energy, transport and medicine. Try our tool for free and be the next to automate your safety analysis.

Safety Architect Naval Group

DCNS achieve most of its fighting system risks analysis with Safety Architect. It is used since 2010 and DCNS has made it a habit to work with it on the fighting system studies. The tool is more user friendly than Excel to build FMEA. What are the tool strengths?

  • Interface with modelling tools
  • Time saved on the analysis recovery
  • Friendliness
Romain PALUD, Ingénieur Safety NAVAL GROUP

Safety Architect Thales

The assets of Safety Architect are the following: a tool easy to take in hand, an understandable methodology, and readable models. Our ambition today is to extend the tool interface with MBSE practices in order to coordinate these approaches.
