The RATP group is modernizing Paris' public transportation network, which includes managing complex integration projects across metro, tram, and rail systems. They deployed CAPELLA to help optimize their systems engineering approach and manage this complexity. RATP took a cautious approach, prioritizing high-value uses of CAPELLA to minimize risks. They have found benefits like improved sharing of concepts, design structure and clarity, reuse across projects, and time savings. RATP is working to qualify more CAPELLA uses and share lessons learned.

4 designs to be carried out at the same time
Ambitious rolling stock renewal programs
for the next 10 years
2022 : new rolling stock « TW20 » for tramway lines
2020 : new rolling stock « MP14 » for automated metro lines
2024 : new rolling stock « MF19 » for manual driving lines
2025 : new rolling stock « MING » for the commuter rail line RER B

6. 6
Modernisation of 13 RATP railway lines
Several system integrations to be performed
Tramway TW20 : 1 lines
Metro MP14 : 3 lines Metro MF19 : 8 lines
Train MING: 1 co-operated line

Our Challenge
Optimize our systems engineering approach
to manage the complexity of different contexts and have
a greater cross-functional approach

Feedback on ARCADIA
and CAPELLA
deployment

20. 20
Benefits of CAPELLA (and ARCADIA Method)
Co-working Capella helps us sharing ideas and concepts thanks
to one common language
Structuration Separation between OA, SA and LA helps us
clarifying design responsibilities within our
organization
Mutualization Capella eases design mutualization for multiple
projects through model sharing
Coherence Capella helps us to guarantee coherence thanks to
automatic update and verification of diagrams
Publishing M2DOC allows us to continue to publish the usual
documentation with all the benefits of the model-
based work
Time saving CAPELLA allows us to instantiate several
modernization projects in a short time and produce
key documents

21. 21
Next steps
Within RATP
• Qualify more usages
• Share the feedback
• Train staff
• Formalize methods

22. 22
Next steps
Waiting for CAPELLA
• Ease beautyfying activities (diagrams
organisation, printable view)
• Improve generated diagrams around functional
chains (SFCD, LFCD, ES)
• Ease model exploration from macro to micro
and from OA to LA
• More ergonomic management of libraries
• More ergonomic way of updating users
environment (CAPELLA + plugins)
