Safety Architect is a Model-Based Safety Analysis (MBSA) tool which automates the creation of safety artefacts required to carry out safety analysis such as: FMEA tables or fault trees. Safety Architect proposes a graphical editor to safety engineers allowing them to manipulate safety concepts in a more comfortable way than with tabular sheets. On the other hand, Safety Architect also ensures consistency between system design and safety analysis by interfacing with Model-Based System Engineering (MBSE) tools such as Capella. Safety Architect leverages Sirius technology to support dedicated graphical representations, specific functionalities and custom mechanisms for safety engineering.

• Many different diagram representations to assist safety engineers
‐ System architecture
‐ Local safety analysis
‐ Fault trees
‐ Risk report
‐ Safety-Security combined analysis
• Implementation of ELK (Eclipse Layout Kernel → automatic layout
for diagrams) to ease diagram design
• Bridge and connection between Capella and Safety Architect to
support MBSE-MBSA
Let’s see in demo !

10. Conclusion
10
Pros:
‐ Native implementation and connection with the EMF metamodel
‐ Style customization
‐ Many features are managed by default (layers, undo/redo…)
‐ Quick prototyping
Cons:
‐ Specific behaviour are difficult to implement (border nodes management, custom action on drag
and drop)
‐ Some ergonomic tips which need to be improved (alignment between non-siblings elements,
default layout of links)
‐ Menu language only in English
Perspective
‐ Investigation with Sirius Web for our future tool based on web interface
