Watch the replay:      GfSE local - Der lange Weg vom Angebot zum Projekt, unterstützt durch Capella Co-organized by Gesellschaft für Systems Engineering e.V. and Obeo The lecture shows the "long way" from the offer model to a project model in Capella®. In addition to questions such as "What can be reused from the quotation model?" or "How can we quickly increase the number of system architects working on the project?" , some of the pitfalls on this path are also presented. The following key statements result from the experience of using ARCADIA and Capella® even in the early phases of a project: The methodology and the tool can also be used profitably in an offer phase, if you limit yourself to the necessary parts, so that the offer team gets a uniform view of the design.This offer model can be used in the implementation project, whereby the focus is on the functional aspects and their description.Focusing on critical areas, such as functions that have a safety...

Discover the replay of the webinar (Thursday, December 19th, 2023) Making Arcadia work for you - a look at framework tailoring in Thales UK   Architecture frameworks provide an approach to describing systems and the presentation of these elements and relationships to deliver the stakeholder needs. Essentially, frameworks provide templates for our engineering artefacts.The design of a framework must accommodate a level of freedom in its usage; specific enough to answer the majority of stakeholder concerns, whilst generic enough to allow for differences between projects. This balancing act often results in framework design being more generic to allow for a wider audience. Having an untailored framework, which is more ‘open’, can lead to creating inconsistent viewpoints.Arcadia is one such framework as implemented through the Capella tool. The framework provides 4 perspectives/levels for product definition:- The Operational Analysis, where the user needs are considered. Note: n...

Watch the replay:  Model Simulation and Analysis in Capella Through a large number of engineering practices in China, we found that customers not only pay attention to how the object product can be modeled more quickly and reasonably, but also pay attention to the correctness of the model itself. Therefore, the simulability and analyzability of the model are very important. Users expect Capella to provide value in logic simulation and parametric analysis. According to the needs of customers, improvements have been made in the following aspects: 1. We decided to add the concept and related elements of activity diagrams in Sysml to Capella to make the function flow executable;2. Referring to the state machine specification in Sysml, we assign dynamic execution rules to the elements in the Capella state machine so that they can be simulated and operated;3. Support nested calls and interrupt logic between state machines and activity diagrams to enrich the simulation scenarios.4....

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...

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.
