Arcadia

The ARCADIA systems modeling method (www.polarsys.org/capella/arcadia.html) was designed by Thales for its own needs. Since 2011, it has been applied to a growing number of projects in a wide range of fields (avionics, rail systems, all-terrain defense systems, air traffic control, control command, zone monitoring, complex sensor systems, satellite systems and ground stations, communication systems …), and in many countries.

The method is supported by a dedicated tool, named Capella, made available free of charge to the community in Open Source mode.

ARCADIA is a structured engineering method designed to define and validate the architecture of complex systems. It promotes the collaborative work of all stakeholders of the engineering phase (or definition) of the system. It makes it possible to carry out as early as the definition phase the iterations that will make it possible to converge the architecture towards the adequacy to the set of identified needs.

The general principles of ARCADIA are as follows:

  • All engineering stakeholders share the same methodology, the same information, the same description of the need and the product as a shared model;
  • Each set of constraints (for example: security, performance, cost, mass …) is formalized in a “viewpoint” with respect to the requirements of which the proposed architecture will be verified;
  • The rules for early verification of the architecture are established so that the proposed architecture can be checked as soon as possible;
  • The co-engineering between the different levels of engineering is supported by the joint development of models, and the models of the different levels and specialties are deduced / validated / related to each other.

Arcadia trainings by PRFC

> MBSE with Arcadia (3 d)

This in-depth training will allow you to discover the ins and outs of the Arcadia MBSE method (Architecture Analysis and Design Integrated Approach), initially developed by Thales for its own needs. Through a case study guided by the trainer, we will go from requirements to the physical architecture of a system through system analysis and logical architecture. We will see how modeling techniques relate to requirements engineering, architecture evaluation, verification and validation, and so on. We will also emphasize the benefits of tooling adapted to the method, through examples and demonstrations of the Capella tool. A language, an approach, a tool: these are the three pillars for the success of MBSE.

> Capella in action (4 d)

This in-depth practical training will allow you to discover the ins and outs of the Arcadia method and associated modeling language, by example. We will focus mainly on the benefits of tooling adapted to the method, through a complete case study with the open source tool Capella. A language, an approach, a tool: these are the three pillars for the success of Model Based Systems Engineering (MBSE).
