Discover both Capella and Arcadia with an example of product design Learn how to build a toy catapult system thanks to the Arcadia method and the Capella open MBSE tool. In this Webinar, We: - Distinguish between systems engineering, which is concerned with the entire design-build-test-deploy cycle of systems development, and systems architecture, which is concerned with system concept development and architectural design. - Contrast the System Modeling Language, SysML, appropriate for systems engineering, with the more focused tool, Capella, and its associated methodology, Arcadia, which is more appropriate for systems architecture development. - Provide an overview of the attractive features of Capella, from the point of view of initiating modelers into the language of systems architecture and briefly demonstrate our longer free public tutorial. This webinar was driven by Professor Peter L. Jackson Pr. Jackson is Head, Engineering Systems and Design Pillar at Singapore University of Technology and Design. He served as the Director of the Cornell University Systems Engineering Program and led the introduction of its online Master of Engineering degree program in systems engineering ranked in the top eight such programs by US News and World Report. He published over thirty articles and is the author of an introductory text on systems engineering, 'Getting Design Right: A Systems Approach'. He is a celebrated instructor of industrial engineering and the creator of dozens of experiential learning games and tools.

The Operational Analysis described is the previous article, MBSE with Arcadia method step-by-step: Operational Analysis [1], involves defining and creating a domain model, independently of the future system to be realized. The principle is to create a level of abstraction from the system under study in order to focus on the needs of the different stakeholders. The System Analysis level, on the other hand, is where the System-of-Interest (SoI) to be defined emerges. The following questions for the system definition needs to be answered: • What must the system do? • What are the external interfaces to the system? In order to answer the first question, the expected behaviour is modelled as Functions.

STEP (Spherical Tokamak for Energy Production) is a £220M project aiming to develop a conceptual design for a First of a Kind (FOAK) commercially viable Fusion Power Plant by 2024. Designing a power plant at this scale comes with immense challenges: Systems engineering approach is relatively new to the industry, where the industry has been heavily research based and engineering processes are not fully in place. UKAEA, the organisation running the STEP project, is applying Model-Based Systems Engineering using the Capella tool. The focus of our approach in managing the complexity of the system is to perform system analysis and logical architecture analysis, to generate engineering artefacts from the model. Through NGO (Needs, Goals, Objectives) analysis key system capabilities were realised to functional chains, which forms the basis for further refinement of the Logical Architecture. The differentiation between logical and physical architectures has ensured that the design stays at the logical space and the team focuses on defining the problem space. This approach has improved interface management process, by creating model-based interface documents, using the model as ‘single source of truth’ to achieve consistency. The architecture definition activities allowed early formalisation of the textual requirements, to drive detailed engineering design in the next phase. Adopting Capella comes with challenges - one of which stems from the unique characteristic of the concept phase – the need to generate architectural variants and evaluating them. The framework and the language are limited in performing variant modelling, a topic UKAEA plans to investigate further. Another challenge was that middle-out approach was favoured for STEP whereas Arcadia method prefers the top-down approach. Throughout this journey, adopting Capella with its use-friendly interfaces has allowed us to better engage with the programme in the MBSE approach and indoctrinate better SE practices.

Model-based systems engineering has developed significantly over the last few years, resulting in an increased usage of models in systems specification and architecture description. The question of the positioning of requirement engineering versus MBSE is a recurrent one. This talk describes one vision of this articulation where textual and model requirements actually complete each other. The results are improved contracts across engineering levels and more formalized V&V practices. Stéphane Bonnet, Thales Corporate Engineering Stéphane Bonnet is in charge of Thales Corporate MBSE Coaching and Design Authority of the Capella open source modeling solution. For the last ten years, he has led the development of Capella and has been an active contributor to the Arcadia model-based method for systems, hardware and software architectural design. In Thales, he is animating a wide community of modeling experts from all domains and countries to investigate low-maturity modeling topics, capture end-user needs, and orient method and workbench roadmaps.

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 introduced how to embed Python or MATLAB® codes inside functions to do “simulation” within Capella.

The NASA System Engineering (SE) handbook aims to provide general guidance and information on systems engineering, as it should be applied throughout NASA. The handbook introduces 3 common technical processes. One of these, is the System Design Process, describing the stakeholders expectations, requirements definition, logical decomposition and design solution definition. The 4 activities can be supported by a Model-Based Systems Engineering (MBSE) approach. To do so, an appropriate method and tool is necessary as the one provided by the ARChitecture Analysis & Design Integrated Approach. ARCADIA, with its modeler CAPELLA, is a MBSE solution supporting system modeling activities. Based on 4 architectural layers, which are Operational Analysis, System Analysis, Logical and Physical Architecture, it is a structured architecture engineering method for defining and validating multi-domain systems. This talk will present an educational overview of the ARCADIA methodology and System Design Process from the NASA SE, by introducing MBSE artefacts for space system. The HUBBLE Space Telescope (HST) is a Cassegrain reflector telescope. Orbiting above the earth, HST elaborates a clear view of the universe free from the blurring and absorbing effects of the atmosphere. In order to illustrate the journey throughout CAPELLA, the HST will be introduced, as example, based on public information available.

Leak Ddetection feasibility study iFluids Engineering A pipeline leak detection system (PLDS) is an increasingly standard component of a modern pipeline control system. Pipeline operators function today in an environment where leak detection systems are seen as a condition of operation mandated via the legal code and enforced through both the courts and regulatory mechanisms and agencies. PLDS system requirements have generally become more stringent with time. Prudent operators responsible for ensuring compliance with regulatory requirements for leak detection systems must: • Clearly identify regulatory requirements. • Define application requirements. • Select an appropriate leak detection product. • Initially test and validate system performance. • Perform recurring testing and validation. a-survey-on-gas-leak-detection-and-localization-techniques The Importance Of The Right Instrumentation For Pipeline Leak Detection In this era where pipeline infrastructure is badly needed to bring liquid products from new plays to market – finding a path to build new pipelines has been increasingly difficult. Politics aside, there is no question that environmental, health and safety are the main concerns when it comes to permitting and building pipelines, and we’ve seen many major projects stalled or cancelled over the past 5 years. The good news? Pipelines remain the safest and most efficient way to transport liquid product, which ultimately bodes well for the industry as expansion is needed. As a collective - however – the industry needs to make a much better case in the court of public opinion if we ever hope to quell the fears prevalent among the discussion.

There is no doubt that agile is an accepted development methodology. However, if you work in a regulated industry like health care where you have to comply with its standard operating procedures, heaps of paperwork, and frequent audits, don’t these conflict with agile’s core tenets? Chris Ampenberger describes his operating environment and the applicable regulations that define the constraints for the software development process he can use. He shares how they overcame the incongruity between agile and regulatory requirements. With real-world examples, Chris demonstrates how you can produce the required documentation as a byproduct of the scrum team’s everyday work and illustrates how his teams succeeded in an agile way, achieving significant increases in productivity. Chris points out common pitfalls, details the hurdles they had to overcome, and discusses how to obtain buy-in from stakeholders at all levels of the organization. If you are working in a regulated environment, this session is for you.
