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.

  6. 6. SA - Software tool presentation 6 • Main goals 1. To provide a dedicated tool for safety engineers FTA FMEA / FMECA FHA, HARA Global Analysis
  7. 7. SA - Software tool presentation 7 • Main goals 2. To ensure consistency between system design and safety analysis: MBSA → MBSE – MBSA Modelling Local Analysis FTA FMEA / FMECA FHA, HARA Global Analysis
  8. 8. • Main goals 3. To interface with other engineering tools SA - Software tool presentation 8 System models IBM Rhapsody System Modelling Workbench Security data Fault trees Reports MBSE - MBSA Safety – Security co-engineering TeamCenter PLM Requirements
  9. 9. SA – Sirius-based features 9 • 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. 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
