Project's team CoSMoS.

Following the completion of the S2C (System & Safety Continuity) project, a collaborative inter-IRT project involving Saint Exupéry and SystemX, focusing on digital continuity between system definition and safety analyses, IRT Saint Exupéry decided to launch a follow-up: the CoSMoS (Collaborative Safety (&RAMT) Modelling Studies) project. Begun in March, this is an opportunity to look back on the success of the S2C project and to take stock of what is expected of the CoSMoS project.

To improve this understanding of system dysfunctions as early as possible, the IRT Saint Exupéry and SystemX had launched in 2019 a collaborative project S2C (System & Safety Continuity) alongside 14 partners, industrialists, academics, software editors and engineering specialists around a budget of 3.8 million euros.

The IRTs have worked on three complementary and interdependent areas of work:

The consistency of System Engineering (SE) / Safety Assessment (SA) engineering data in a co-engineering process: supply of a set of models (process, data-model, traceability plan, other models, etc.) and recommendations to guarantee the consistency of engineering data shared between the SE and SA teams.

A practical MBSA guide: this gives the keys to start a modelling project, as well as the tricky points and pitfalls to avoid for a RAMS engineer used to traditional methods such as fault trees (FTA).

Consistency between MBSE and MBSA models: three different methods have been developed and tested on the IRT Saint Exupéry’s case study, the AIDA UAV, and propose ways of collaborating further upstream between these specialists, using tools to identify potential inconsistencies.

As part of the CoSMoS project, the IRT Saint Exupéry will continue its coherence work on operational safety analyses executed at different system levels, carried out in an extended enterprise context, alongside Safran, Airbus Protect, Satodev, LGM, ONERA, DGA and Naval Group.

With a duration of three years and a budget of 2 million euros, the aim of the project is to increase the maturity of the use of MBSA analyses in order to combine them with each other, but also with traditional FTA-type analyses, to reflect the heterogeneity of industrial practices, favouring collaboration between customers and suppliers.

Ultimately, the aim is to be able to share part of the information relating to Safety (&RAMT) analyses on operational projects with different stakeholders. A methodological framework is expected as a deliverable, setting out how people can work together. It will then be validated by the use of the project partners’ tools (SimfiaNeo and Cecilia Workshop), enhanced by this method, on public and private case studies.
