Watch the replay:   Simulation with Python and MATLAB® in Capella A common need in system architecture design is to verify that the architecture is correct and can satisfy the requirements. Execution of system architecture model means to interact with state machines to test system’s control logic. It can verify if the logical sequences of functions and interfaces in different scenarios are desired. However, only sequence itself is not enough to verify its consequence or output. So we need each function to do what it is supposed to do during model execution to verify its output, and that is what we called “simulation”. This presentation introduces how to embed Python or MATLAB® codes inside functions to do “simulation” within Capella.   Renfei Xu Renfei Xu is the Technical Director of MBSE from PGM. He has participated in many implementation projects of MBSE in areas like Engine Control, Avionics, Mechatronics, RADAR and so on. In recent years, he is dedicated to th...

Watch the replay:     Applying MBSE as support for Systems Engineering Standards How to efficiently apply recommended practices of Systems Engineering: The Health Agriculture UAV case study With the emergence of Cyber-Physical Systems (computer systems in which physical elements are controlled or monitored by computer-based algorithms), defining a solution that satisfies stakeholder needs and various constraints is a hard task to complete. This is the reason why the Systems Engineering community defined standardized practices (such as the ones defined in ISO15288:2015), to realize successful systems, several years ago. However, performing these practices with the traditional "document-based" approach may be limited due to the difficulty of checking the overall consistency of the engineering documents. Using MBSE methods and tools (such as proposed by the ARCADIA method and Capella tool) is a great help to support the stakeholder requirements analysis and system requirem...

Watch the replay:   SES ENGINEERING Studio: Achieving the perfect equilibrium between Textual Requirements and Models in Capella enhanced by Automatic Interoperability, Quality & Traceability operations. The importance of models is imperative in any Systems Engineering project. However, truth is not exclusively found within models. The need to describe external contracts, regulations, or non-functional requirements, for instance, can be more efficiently satisfied by using textual specifications. In order to achieve the desired “Common Source of Truth”, model and textual requirements must be connected and coexist, desirable enhanced by the automatization of the consistency checking, automatically modifying one side when changes are produced on the other end... Within The REUSE Company, we have realised how crucial it is to facilitate this connection and provide Systems Engineers with the tools required for applying SE across the entire process as seamlessly as possible.

Watch the replay:      E/E systems and cyber-physical systems are carrying out more and more advanced and safety critical features in many domains such as transport, energy, industry, farming, medical, etc. Therefore, during last few years, to manage the development of those complex systems, companies have moved from a document-based approach to a model-based approach associated with very specific tools. However, system and safety engineering, and some other related engineering domains like cybersecurity for instance, are still too often conducted independently, whereas safety and system attributes are largely interdependent. There is a need to foster greater collaboration between these disciplines to avoid errors and also to maintain time-to-market. That's why since several years, ALL4TEC, with its safety analysis tool Safety Architect, has been working to connect its tool with system solutions to couple MBSE and MBSA. The goal is to better ensure consistency bet...

This webinar was held on Tursday, April 21st. Discover the replay:   Nowadays, we are surrounded by system of systems, autonomous systems, interconnected systems or distributed heterogeneous systems with an increase in architecture complexity. Keeping these systems operational is a challenge as the number of potential failures which may affect their availability also increases drastically. In order to optimize availability, maintenance activities have to be designed within the design phase of the system. Whatever the implementation choice, detection, diagnostic or prevention of failures require tests. The goal for autonomous systems also pushes towards embedded detection and prevention capabilities and thus arguing and decision making between system engineers and maintenance engineers to share solutions in their respective activities. In this presentation, we talk about the ability of a system designed with Capella to be tested : what are the interconnections between eng...

Thursday, January 20th, 2022 - 5:00 PM CET / 11:00 AM EST This webinar has ended, but feel free to watch the recording.   The slides of the presentation are available here: https://bit.ly/capella_webinar_220120_slides With such a name, Capella, the brightest star in the constellation of Auriga, was undeniably destined to meet space. Previously, it landed in the French Space Agency (CNES) to demonstrate that the current document-centric process can be improved by injecting a (huge) pinch of Capella models slightly extended by new features dedicated to system test specification. Applied on the “Space Variable Objects Monitor (SVOM)” operational use case, it helped the CNES in the definition and the validation of its future space system dedicated to the gamma ray detection and study. Proof being made, this experience propels Capella to another space company, Kinéis, created by CNES and CLS to strengthen the historical and reputed Argos IOT service, ensure its continu...

Thursday 2nd September 2021, Obeo organized a Capella Webinar This webinar has ended, but feel free to watch the recording.   When designing increasingly complex systems, engineers need to master the behaviour of the solution they will deliver, throughout the engineering life-cycle.  Arcadia and Capella MBSE practices allow them to share a common understanding of the foreseen solution and to secure the solution definition. In some cases, engineers need to execute their architecture models to early validate the specified behavior, to perform architecture tradeoffs and to provide a reference for further implementation.   This webinar, was presented by Pierre Nowodzienski, Simulation & Digital Twin expert at Thales, who presented how we address these needs by coupling the best-in-class architectural design practices provided by Capella with the powerful simulation capabilities provided by Matlab Simulink. If you are interested in discovering ne...

Thursday, May 27th, 2021, Obeo organized a Capella Webinar. This webinar has ended, but feel free to watch the recording.   While MBSE has a growing momentum, transforming engineering practices is still a major challenge today.   The Capella tool, through multiple feedbacks and its rapid adoption by the systems engineers community, constitutes a major enabler for the success of this journey. The Arcadia method plays a significant role, by offering a pragmatic vision of MBSE, centered on the practices and concerns of systems engineers. The holy grail of the single source of truth is at hand. But a tool like Capella is part of a larger ecosystem of engineering tools. The next challenge is now to make this repository of system data available to all stakeholders and to break down the silos between our engineering activities.     This webinar, after having introduced the problem, will illustrate how Publication for Capella and Cloud for Capella contribute&nb...

From Monday 12th to Friday 16th, there were plenty of events that were rich with online MBSE events from all over the globe, we had the pleasure to attend talks about Eclipse Capella and MBSE in Asia, Europe, India, and the USA!    So which events were Capella included in? CSDM Asia organized by CESAMES Asia-Pacific was held in Beijing (and online). We were very happy to support this main event on how to master complex engineered systems. Capella also sponsored the MBSE Summit 2021 organized by the INCOSE India Chapter and the Aeronautical Society of India, which had plenty of fascinating talks on MBSE. including an introduction to Capella and Arcadia by Stephane Lacrampe. Within 'the MBSE Applied track' by TNO-ESI, we learned more on the application of Capella and MBSE with Jim Daly from Rolls Royce’s talk: 'MBSE for complex system of systems' As part of the Swiss Society of Systems Engineering's MBSE initiative, Juan Navas presented how MBSE has contributed to the ...
