Replay of Capella Webinar - Tuesday, September 23, 2025     Capella in Transport and Infrastructure   Capella brings significant advantages to transport and infrastructure projects through its use of the ARCADIA framework. This includes structured use of Physical Architecture Nodes, Behavioural Components, and Functional Chains, enabling clear modelling of system behaviour and interfaces. The REC/RPL paradigm supports rapid scaling of models with repeated elements, common in infrastructure and transport systems, while functional and component exchanges naturally reflect logical and physical interface patterns. These features provide a solid foundation for interface documentation, further enhanced by Capella’s document generation capability, which enables efficient, repeatable production of artefacts at scale where many documents need to be produced.   ***  Presented by: Tim CarterClarity SE Tim Carter is a professional engineer with 25+ years...

Replay of Capella Webinar - Thursday, May 15th, 2025   MBSE Approach to Creating and Exploiting Digital Systems for HORIZON Europe   This presentation is based on Horizon Europe Project Demo-BLog where the business needs where pre-defined, and the challenges focused on defining requirements at an abstract opportunity/problem space domain level for an automated renovation advice tool. To accomplish this task, a System Definition process was undertaken to achieve the Engineering solution space domain. And to achieve the System Definition methodology the author decided to focus on first creating an Interface Control Document that consisted of high-level overview architecture of the target system CLEA (Digital Building Logbook) and the source system BDNB (Base de Données Nationale des Bâtiments). However, the alternative architectures presented challenges such as how to validate the requirements at this stage. The chosen tool/technique was THALES (Model-Based System Engin...
