Forget your Excel worksheets ! The model based safety analysis is coming
Safety engineering purpose is to ensure that a life critical system behaves properly, even when a failure occurs. The application field are various : nuclear reactors, medical systems, military equipments, etc. The result of their analysis is obviously crucial. In this case, why most of them are done on Excel worksheets or even with a simple pen ?
Of course, the safety engineering relies on standards and methods, and the work of the safety analyst consists mainly of its understanding of the system and its experience. However, use a tool can dramatically ease its tasks and reduce the risk of manual errors. An other way to improve its efficiency is to work directly on the system models. This is what we offer with Safety Architect.
Model Based Safety Analysis (MBSA) aims to provide a model to automatically perform classical safety analyses such as Fault Tree Analysis (FTA) or Failures Modes, Effects and Criticality Analysis (FMECA). MBSA is a sub discipline of Model-Driven Engineering (MDE) which is a methodology aiming to base system development on the creation, the refinement and the integration of models.
That is why ALL4TEC has systematically based all its safety studies on model based analyses, and has developed its own solution. Safety Architect is a tool achieving risk analysis of complex systems using functional or physical architectures from usual modelling tools (for example SysML or UML). It provides support to the implementation of FMEA and automatically deducts the FTA corresponding to the identified feared events.
This talk will give you a broad overview of Safety Architect, and our feedbacks coming from the conception of this new product : why using Eclipse RCP, why integrating a modeller, which technical components are used, etc. ? Moreover, this talk will be the opportunity to announce the new Open Source strategy of our society, and that Safety Architect will soon be shared with the Eclipse Community.
