As system architecture is central to developing complex systems, making Capella models accessible to all stakeholders is key to keeping every discipline aligned. This is especially true when working on traceability coverage or managing regulatory compliance, where teams need to view, manage and navigate links between model elements, requirements and test cases.

In this webinar, you will learn how to publish Capella models to a controlled web server, making them easily accessible to your teams, and how to have bidirectional navigable traceability between Capella model elements and Jama Connect® artifacts.

This integration, provided by Obeo as part of Publication for Capella, replaces error prone manual checks by a smooth toolchain keeping all artifacts synchronized throughout the development lifecycle.

It also makes it easier for stakeholders to view, interact and navigate across any System Engineer data through web servers no matter were is stored the data: in Capella or in Jama Connect.

Finally, it enables the systems engineering team to detect issues earlier and reduce defects and rework, by ensuring that all stakeholders can quickly reach the most recent and complete information about system architecture, and related requirement and test case at any time.

As system architecture plays a pivotal role in the development of complex systems, it is essential to make Capella models accessible to all stakeholders to ensure alignment across disciplines. These models should also be connected to change management tools and naturally integrated within the broader system engineering documentation.

In this webinar, you'll discover how to publish Capella models to a web server and establish bi-directional connections with Confluence and Jira:

• make Capella models easily accessible to teams and partners;
• create links between Capella model elements and related content documented in Confluence;
• embed Capella diagrams and model descriptions directly into Confluence pages;
• enhance coordination between system architecture and project management workflows tracked in Jira.

This solution combines Obeo’s Publication for Capella add-on with SodiusWillert’s OSLC Connect for Jira and OSLC Connect for Confluence.

By closing the gap between architecture, documentation, and task tracking, this integration fosters better collaboration and alignment around a shared vision of the system under development.

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 Engineering) – Capella Tool and Arcadia Methodology. The article presents this approach, which included: operational analysis, system needs analysis, logical architecture and discussions reflecting the physical architecture relating to the requirement phases of need understanding and solution architecture design.

The outcome of this presentation is The French Demonstration Preliminary Requirements and acknowledgement to the benefits of MBSE: Improved communications, Increased ability to manage system complexity, Improved product quality, Reduced Recycled Time, Reduced Risk, Enhanced knowledge capture and reuse of the information.

Modern systems have become more and more complex, requiring the use of a wide range of tools to successfully manage their development. Considering this situation, seamless connectivity and interactions between those tools is of paramount importance to build a consistent and valuable digital thread.

As many development programs involve different organizations, there is also a growing need for connecting digital threads together to facilitate decision making. This poses a challenge of building interoperable toolchains that enable collaboration, data exchange and global configuration management along the system life cycle.

Capella, while offering an excellent framework for program collaboration and systems of systems development with the ARCADIA Method, can participate in this endeavour by being integrated into a Synchronized Source of Truth (SSoT) that gathers all systems engineering assets. Some tasks and processes that would nurture this synchronized repository are:

• Bi-directional System/System element requirements synchronization and traceability,
• Requirements attributes and consistency check,
• Model synchronization between organizations,
• Model conversion (SysML to ARCADIA),
• Life Cycle-wide configuration management,
• Model element reports publication.

This talk will show how the integration of Capella models into SES ENGINEERING Studio’s multi-activity platform can benefit to collaborating organizations in development programs, ensuring data exchange and synchronization as well as ontology-controlled requirements management.

The use of Unmanned Aerial Vehicles (UAVs), specifically VTOLs, in search and rescue missions is key for quickly locating victims in emergencies. This presentation will focus on designing and validating an integrated system, composed of search and rescue drones, utilizing Model-Based Systems Engineering (MBSE) with Capella to ensure coordination between mission components. Capella ensures all elements work together efficiently, optimizing response in critical situations.

Search drones, equipped with high-resolution cameras, thermal sensors, and GPS, detect, track, and map difficult-to-reach areas, facilitating precise identification of victims in complex environments. Capella ensures the correct integration of these drones with other mission systems, such as rescue drones and ground teams, ensuring smooth transfer of critical data like victims' location and terrain conditions. This optimizes decision-making and real-time coordination, maximizing mission effectiveness.

The rescue drone, in addition to transporting medical supplies, can carry two rescuers directly to the victim for necessary rescue and evacuation tasks. Capella facilitates traceability of requirements for both systems (search and rescue), addressing critical aspects for mission success.

Integrating advanced technologies like AI and machine learning enhances real-time decision-making, improving victim detection. Using MBSE and Capella ensures that each system component is validated and effectively integrated into the mission, which is crucial for increasing rescue mission effectiveness.

With the Arcadia method implemented by Capella, engineering is considered through three interrelated activities of equal importance:

• Requirements engineering
• Need analysis and modelling
• Architecture building and validation

The first is generally conducted with a Requirements Management tool (such as Doors or Polarion), while the last two are conducted with Capella.

Using different tools raises questions about efficiently maintaining consistency and alignment between the architecture models and the requirements, and exposing a consistent integrated view of this interrelated data.

During this webinar, you will see how the Publication for Capella add-on enables publishing Capella models on a web server and connecting them with requirements, change requests, test cases, releases, and more, defined in third-party repositories.

This solution breaks down silos between teams by providing online access to an integrated view of your system architecture. It facilitates your engineering teams' ability to reuse work items and system elements in a consistent and aligned process.

Working with Capella models traditionally involves managing files, which requires careful coordination among team members to handle concurrent work. This often means having to establish strategies for reserving files or resolving conflicts after changes overlap.

By switching to multi-user mode in Capella, you can significantly enhance collaboration among your team of systems architects. This mode helps avoid the tedious management of file differences and reduces the risk of data loss.

Multi-user mode allows team members to work simultaneously and safely on the same model by using:

• A shared repository installed on a server to store the Capella model.
• An add-on in your Capella workbench, activating a fine-grained locking mechanism that reserves model elements being edited.

These components work in sync to automatically release locks when modifications are saved and make them available to all connected users.

During this webinar you will discover Team for Capella, an add-on that implements this approach to provide a seamless multi-user experience.

He graduated from ENSTA Bretagne, a French State Engineering School.

In today's transforming industry, Model-Based approaches are often seen as an add-on, further complicating the already complex work of systems engineering and software development. But what if it did not have to be this way?

At GU Orbit, we have adopted the Arcadia method exactly to make the process of engineering complex space systems more accessible to undergraduate students. With its multi-level workflow, repetitive activities, and opinionated semantics enforced by the Capella tool, it effectively guides even inexperienced users in the design of rational systems. Additionally, taking advantage of its semantic similarity to the European Space Agency's TASTE toolchain for embedded software development, we have devised an overarching methodology to rigorously bridge the gap between high-level system specifications and low-level component code.

This Arcadia-based method comprises the entire systems engineering lifecycle in a unified V-shaped model. The design phase is performed in Capella, regularly traversing all main functional decomposition levels. Specific physical-level views are then used to translate the resulting model into TASTE, trivialising the implementation phase down to individual lines of code in the Specification and Description Language (SDL, ITU-T Z.100) and C/C++. Finally, the verification and validation phases are carried out at all levels of abstraction by comparing specific TASTE-generated diagrams, such as State Chart Views and Message Sequence Charts (MSC, ITU-T Z.120), against their Capella-defined counterparts.

In this webinar, we will illustrate this method in the context of GU Orbit's student-led development of autonomous nanosatellite avionics, which were successfully demonstrated during an early stratospheric balloon flight.

Giorgio Ciacchella is Project Manager and Systems Engineer at GU Orbit. He is a Masters' student of Electronic and Software Engineering at the University of Glasgow, where he leads the local nanosatellite club GU Orbit.

He is interested in research and development on formal, model-based methods and tools for systems and software engineering, particularly targeting the embedded domain; his first publication (An Open-Source Method for Model-Based Development of Embedded Systems: Experience Report from a CubeSat Student Project) was awarded as the best work in its category at the 2023 International Astronautical Congress.

In today's complex systems engineering landscape, Capella has emerged as a powerful tool for model-based systems engineering (MBSE). This presentation explores key enablers for Capella champions to ensure the successful adoption and utilization of Capella within an organization.

Training: Effective training is foundational for developing Capella champions. Tailored programs, from beginner to advanced levels, empower individuals to become proficient in Capella. Strategies for designing training programs aligned with organizational goals are discussed.

Extensible Authoring: Capella's extensible authoring capabilities allow customization to specific domains and engineering practices. Developing custom viewpoints, libraries, and domain-specific extensions is crucial for a seamless fit with organizational requirements.

Accessible Model Content: To maximize the impact of Capella models, enabling non-authors to access and utilize model contents is essential. Strategies for visualization, reporting, and data sharing allow stakeholders to extract insights and make informed decisions.

Fostering Capella champions is crucial for successful MBSE adoption. Through comprehensive training, enhanced authoring capabilities, and enabling non-authors to leverage model contents, organizations can unlock Capella's potential, driving efficiency and innovation in systems engineering. This presentation offers practical guidance for organizations on their journey to becoming Capella champions and realizing the benefits of MBSE.

System Architecture, its derived requirements and systems analysis performed, are often attributed to defining 70% of the cost and capabilities of a system. However, after nearly two decades of Model Based Systems Engineering (MBSE), there is a lack of architecture focused methodologies and tools to aid programs in creating a robust, transdisciplinary system architecture.

One notable exception is the Thales developed Architecture Analysis and Design Integrated Approach (ARCADIA) method and associated Capella modeling tool. The ARCADIA Architecture Development Method (ADM) provides instance-based methodologies for each ADM step with rich viewpoints and views to ensure a robust architecture is obtained. As the goal of the proposed methodology is to rapidly create a robust, transdisciplinary system architecture, ARCADIA was selected for its native alignment with this goal.

However, the ARCADIA method is like a framework and requires a defined methodology to be applied to it to determine what views, and in what order, constitutes the desired architectural model.

The proposed methodology defined these elements based on alignment with the IEEE 15288:2015 architecture standard, and to further the goals of ease of learning, rapid modeling, and reduced modeler workload/errors.

Is your system robust to the loss of one or more functions? Does your system require interaction with other systems to operate safely? Does the design and operational concept of the system include contingency means? Do these contingency means correctly mitigate the risks?

These and other similar considerations are becoming more important with the emergence of autonomous systems and complex systems of systems. The introduction of digital tools and in particular model-based systems engineering allows to capture the complexity of these products starting from the operational analysis and supporting the process throughout the whole product life cycle.

With ATICA, system architects and designers will be able to analyze safety implications starting from the conceptual needs and mission description; modeling risks associated to the system, assessing the probability of occurrence and severity, and deciding upon the needs of contingency and mitigation means. ATICA enriches the Arcadia framework and provides safety analysis capabilities for each step of the system definition, design, and verification process.

In this webinar we will address an example with an autonomous vertical take-off and landing (VTOL) vehicle, conceived for operation in urban environments (urban air mobility). We will present the operational description and system architecture, and we will conduct the Functional Hazard Analysis (FHA) directly from Capella and aligned with the normative standards in force in the aeronautic industry (ARP-4761 / ED-135).

Finally, we will introduce safety analysis covering the logical and physical architecture levels, showcasing the use of Capella, Arcadia and ATICA for Fault Tree Analysis (FTA) and Failure Modes and Effects Analysis (FMEA).

Arcadia is the model-based systems engineering method at the heart of the open-source Capella modeling tool.

Promoting a viewpoint-driven approach (as described in ISO/IEC 42010), it emphasizes a clear distinction between need and solution to support enterprise-wide collaboration and co-engineering.

To help systems engineers master Arcadia, the community continually produces resources in various formats (books, web pages, articles, videos, datasheets, etc.) and for different purposes, ranging from introductions to very precise topics.

During this webinar, you will embark on a journey through the extensive resources at your disposal. Mainly, you will have the exclusive opportunity to discover brand new documents derived from the experience of Jean-Luc Voirin, the principal author of the method, gained through his involvement in projects over many years.

How to make environmentally conscious decisions when designing a system?

Performing a life cycle assessment (LCA) can help you precisely identify the types of impacts a system has, from the extraction of raw materials to its end-of-life phase. However, this is often a tedious process that involves inputting the system architecture into an LCA tool and mapping it to environmental databases. This makes it difficult to repeat the process multiple times for the same system.

So why not reuse your Capella models to conduct LCAs?

Ecodesign for Capella is a new add-on that allows systems architects to enter data on the life expectancy of components, materials utilized, consumptions, and emissions directly in Capella, and automatically generate a life cycle inventory in an LCA tool like OpenLCA.

In the essential collaboration between systems and environmental engineers to reduce the environmental impacts of a complex system, this add-on enables them to make eco-responsible design choices from the beginning, by conducting reliable life cycle analyses, faster and more frequently.

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: no concept of the System at this level.
• The System Analysis, where we define the contribution and scope of the System as a ‘black box’, identifying external interfaces, and top-level system functions.
• The Logical Architecture, where we break the System down into logical ‘blocks’ and decompose the functionality.
• The Physical Architecture, in which we define a (candidate) physical architecture, further decompose the functions, and deploy this functionality to the physical sub-systems, hardware, software and/or firmware.

In this talk, we acknowledge the strengths of the Arcadia framework, and the benefits it brings, whilst considering the need to tailor the generic viewpoints. We will provide examples of how we have adopted the generic Arcadia framework and further specified some of the viewpoints to meet the needs of our stakeholders. We will discuss future work looking at how we can translate these specialisations across other areas of the model. Finally, we will provide some suggestions and advice on tailoring views to meet your own needs and ensuring stakeholder engagement with the model.

Als vor einigen Jahren in Nordeuropa ein großes Projekt im Bereich der Leit- und Sicherungstechnik für Eisenbahnen ausgeschrieben war, hat Thales sich an diesem Projekt beteiligt und dort zum ersten Mal in einer Angebotsphase ARCADIA als Methodik und Capella als Tool für Model-Based-System-Engineering eingesetzt. Auf den Capella Days 2018 wurden von uns die Ergebnisse dieses Einsatzes vorgestellt. In der Zwischenzeit hat sich nun dieses Angebotsprojekt in ein reales Projekt verwandelt.

Damit stellte sich die Frage, wie arbeiten wir in ARCADIA und Capella weiter. Der Vortrag zeigt daher den 'langen Weg' vom Angebotsmodell zum einem Projektmodell in Capella. Neben Fragen wie 'Was kann aus dem Angebotsmodell wiederverwendet werden?' oder 'Wie können wir die Anzahl der Systemarchitekten, die an dem Projekt arbeiten, schnell erhöhen?', werden auch einige der Fallstricke auf diesem Weg präsentiert. Zusätzlich gibt dieser Vortrag Antworten auf Fragen wie 'Welche der verschiedenen Sichten von ARCADIA sind für welchen Zweck geeignet?' oder 'Wie kann man spezielle Themen wie die Kommunikation mit Kunden, die Beschreibung externer Schnittstellen oder Sicherheitsaspekte für ein großes Eisenbahnverkehrsmanagementsystem modellieren?'.

Dr. Michael Schäfer (Thales) ist nach seinem Physikstudium seit 1992 für Thales und die Vorgängerfirmen Alcatel und SEL als Software- und Systemarchitekt in den folgenden Bereichen tätig:

• Software- und System-Engineering, hauptsächlich im Bereich der Anforderungsanalyse für Bahnsteuerungssysteme verschiedener Kunden (in Deutschland, Saudi-Arabien, Dänemark, etc).
• Systemarchitektur, insbesondere modellbasierte Ansätze speziell mit ARCADIA/Capella für Leittechnik im Bahnbetrieb.
• Arbeit als Systemsicherheitsexperte für Eisenbahnsignaltechnik. In diesem Zusammenhang Mitglied in mehreren Standardisierungsarbeitsgruppen der CENELEC.
• Coach und Lead System Architekt für aktuelle Bahnsteuerungsprojekte bei verschiedenen europäischen Bahnen, einschließlich Unterstützung für ARCADIA und Capella.

Seit 2015 ist Dr. Michael Schäfer Certified System Engineering Professional (CSEP) von INCOSE.

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. Support integration and calling with Matlab to make algorithm verification simpler and more feasible.
5. Developed a running interface for simulation, so that engineers can get more information through simulation (for example: simulation animation effect; simulation speed adjustable;

Simulation can be paused; simulation data can be modified in real-time and feedback can be obtained; simulation data can be recorded and related curves generated).

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 those proposed by the ARCADIA method and Capella tool) is a great help to support the stakeholder requirements analysis and system requirements/architecture definition. However, it is sometimes difficult to 'map/instantiate' the standard processes (ISO15288:2015) to implementation using the ARCADIA method and Capella, especially when adapted to the specific practices of each company.

During this talk, you will gain insights concerning the relations between the ISO15288:2015 processes and the ARCADIA approach, illustrated using the Health Agriculture UAV case study, and focus on some common topics such as the implementation of MOEs/MOPs in the model.

A common need in system architecture design is to verify that if the architect is correct and can satisfy its requirements.

Execution of system architect 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.

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. This solution is the SES ENGINEERING Studio, and within this webinar, the following capabilities will be shown:

• The SES ENGINEERING Studio offers the capability to assess consistency between textual requirements and Capella models.
• Automatic generation of Capella models from Textual Requirements inside an RMS (Requirements Management System). This also involves the possibility to complete the exact opposite operation, generating textual requirements from Capella models.
• Seamless traceability management between textual requirements (in any RMS) and model elements in Capella; This includes the possibility to automatically suggest traces based on the semantic content of the textual requirement.
• If the preferred option is to maintain these textual requirements inside Capella, we offer the possibility to provide a round-trip process between any RMS and Requirements Viewpoint within Capella; thus, allowing that modification at either end, to be synchronized.
• Automatic quality assessment of Capella models following a number of pre-established rules or allowing the users to define tailored rules.
• Automatic interoperability between SysML and Arcadia models.

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 between system design and safety analysis.

During this talk, ALL4TEC presented its Capella add-on that allows annotation of Capella models with basic safety information, smart export and dynamic connection to share data between Capella and Safety Architect to support MBSE-MBSA.

Jean Godot joined ALL4TEC in 2018 as a R&D engineer to manage research projects and to participate in the development of Safety Architect. Jean holds a PhD in computer science from Paris-Saclay University in France and his areas of interests are system safety and cybersecurity.

Jonathan Dumont started working for ALL4TEC in 2010 to develop the model-based safety analysis tool Safety Architect. It was the opportunity for him to discover the graphical modeling approach and to start working with the first versions of Obeo Designer. As a technical lead for the ALL4TEC development team, he followed the technological evolutions of Eclipse Sirius and deployed them into several tools developed by his company.

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 talked about the ability of a system designed with Capella to be tested, including in the maintenance phase. This means to interconnect several kinds of models representing different perspectives: System Design (MBSE), RAMS Analysis (Reliability, Availability, Maintainability and Safety) and Testability.

We presented how a MBSE approach with Capella can be used to initiate a testability study performed with the eXpress tool from DSI International.

System of Systems modeling comes with a tough decision for practitioners using traditional SysML V1 tools. Do I go with SysML V1, or do I look at Unified Architecture Framework? Capella eliminates that challenge with one notation that can be used for both.

Tony Komar has been practicing and supporting systems engineering for over 35 years. He is a key contributor to the development and deployment of model-based system engineering products for Siemens Digital Industries Software.

Previously, Capella models (slightly extended by new features dedicated to system test specification) was used by the French Space Agency (CNES) to demonstrate that the current document-centric process could be improved. 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, Kineis, created by the CNES and the CLS, reiterates the experience and continues to make it a strategic technology for science. Its current challenge is to add 25 state-of-the-art nano-satellites to the existing system to enhance IoT capabilities and address new markets. In line with the CNES Capella experience, Kineis decided to build its “System Test” process on Capella.

The extendibility and the flexibility of Capella nevertheless allowed them to carry on the previously initiated toolchain in order to cover the full process and support more use cases

When designing increasingly complex systems, engineers need to master the behavior 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 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.

Discover how Arcadia/Capella is used to model and simulate concept of operations scenarios for CubeSat-based missions. During this webinar, Danilo Pallamin de Almeida, who worked as a Space Systems Engineer for the NanosatC-BR2 mission at INPE, the Brazilian Institute for Space Research, will present how CubeSat-based missions have been modeled with Capella.

The model describing an initial architecture mission and concept of operations (CONOPS) is used to generate a script that configures a satellite simulator with the corresponding mission parameters.

You will see how it allows the INPE to:

• run concept of operations scenarios simulations,
• use the results for power/data-budget analyses and trade studies

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 to making the single source of truth a dream come true.
