Systems Engineering

Your challenges

Designing complex systems

The design of a train, plane or satellite is a multidisciplinary activity that requires the intervention of numerous experts in specific and various fields (mechanics, software, electronics, telecommunications, energy, safety, etc.).

To succeed, this type of project requires the implementation of a Systems Engineering approach and effective communication between the experts throughout the project's life cycle: from the definition of the needs to the maintenance, including the design and development phases.

Today, a classic Systems Engineering approach based on textual documentation is no longer adequate due to the increasing complexity of systems and their architectures.

Tailored MBSE workbench

Our vision

Model-Based Systems Engineering

In order to maintain a global and coherent vision, an alternative is to use a model-based approach (MBSE or Model-Based Systems Engineering).

We believe an MBSE workbench should be:

Adaptable: it should provide specific viewpoints and services well suited to the different steps and stakeholders of your engineering process ;

Open: it should enable integration and interoperability with third-party tools in order to access all design data and to promote information exchange ;

Scalable: it should be easily extended and maintained to support the enhancements inherent to Systems Engineering.

Realistic and pragmatic, this approach, which supports an operational industrialization of Systems Engineering, is a key factor in your competitiveness:

  • Effective decision-making ;
  • Collaboration facilitated between all stakeholders ;
  • Better understanding of system complexity ;
  • Enhanced integration of the various engineering tools.


Obeo's added-value

Faithful to the Open Innovation principles, Obeo is involved in the development of Capella ecosystem, the Open Source MBSE solution created by Thales. We thus bring unique expertise to create tools, on your behalf, that are sustainable, easy-to-use and adapted to your methodology.

Eclipse-based MBSE workbench result

Our solution

Your industrial deployment of Capella

Thanks to our expertise in the Open Source modeling technologies that compose Capella, Obeo is a key partner for a large and successful deployment of this MBSE solution:

  • Development and integration of custom plug-ins to adapt the workbench to your particular engineering concerns (viewpoints, connectors with other tools, documents generators, etc)
  • Distribution of Team for Capella, an add-on that brings additional features enabling you to share models and representations on a collaborative server.

Systems Engineering workbench Melody

The Melody ecosystem is a field-proven modeling solution developed by Thales and Obeo. It offers an environment with a high added-value for engineers working on system, software and hardware architectures.

At the center of this ecosystem is a graphical modeling workbench that provides a focus on functional analysis, (complex) architectures definition and early validation.

Railway safety analysis

To improve collaboration between system designer and safety assurance manager, Alstom has created a specific modeling workbench with Sirius.

Supporting a model-based Systems Engineering methodology defined by Alstom, this tool allows safety engineers to graphically describe their analyses (PHA and SHA) by directly requesting the SysML design model of the system. It strongly couples railway signalling system design with risk and safety studies.

Configuration of space systems middlewares

The CNES has defined a model-based approach to generate RTSJ source code, a Java version designed to support both hard and soft real-time application.

In order to easily configure space systems middlewares, Sirius has been used to complement a UML modeling workbench (based on Eclipse) with a DSL dedicated to the communication protocols.

Reuse of satellites software architectures

Sirius has been used to create a modeling workbench for the European Space Agency that supports a generic architecture for on-board satellites applications.

This workbench aims to make software development faster in the context of a reduced schedule, to allow late definition or changes to cope with the various system integration strategies.
