What is meant by model based systems engineering?

Model-Based Systems Engineering (MBSE) is an approach to system engineering that relies on graphical models to conceptualize, design, analyze, and document complex systems. It involves using:modeling languages like Systems Modeling Language (SysML) or Unified Modeling Language (UML),modeling tools,analysis techniques,and integration methods.The main goal of MBSE is to improve communication, understanding, and decision-making throughout the system development lifecycle.

What are the 3 pillars of MBSE?

The three pillars of Model-Based Systems Engineering (MBSE) are models, methods and tools:Models: The central component of MBSE, models represent different aspects of the system being developed, including its structure, behavior, requirements, interfaces, and interactions. Models serve as a means of visualizing, analyzing, and documenting the system throughout its lifecycle.Methods: MBSE employs various modeling and analysis techniques, methodologies, and processes to develop, analyze, and validate system models. These methods help engineers and stakeholders understand system requirements, define system architecture, simulate system behavior, and make informed decisions.Tools: MBSE relies on specialized software tools that support the creation, manipulation, analysis, and documentation of system models. These tools provide features such as graphical modeling editors, simulation capabilities, version control, and integration with other engineering tools, enabling efficient collaboration and communication among stakeholders.The best example that combine the 3 pillars is our tool CATIA Magic Cyber Systems Engineer.

What is cameo model based systems engineering?

Formerly known as Cameo Systems Modeler, now rebranded as CATIA Magic Cyber Systems Engineer, this advanced modeling tool, initially developed by No Magic, Inc. and currently enhanced by Dassault Systèmes, facilitates Model-Based Systems Engineering (MBSE). By leveraging SysML and UML, users can seamlessly craft, assess, and document system models. With intuitive graphical modeling editors and robust simulation functionalities, it streamlines system development processes while enhancing communication within teams.

Why use model based systems engineering?

CATIA Magic Cyber Systems Engineer, formerly known as Cameo Systems Modeler, empowers users with Model-Based Systems Engineering (MBSE) capabilities. It facilitates improved communication, early issue detection, and deeper system understanding. With its simulation and analysis features, users can thoroughly assess system behavior. Additionally, the tool enables comprehensive documentation with traceability. By promoting collaboration and ensuring designs align with requirements, it minimizes the risk of costly rework.

Define Software Components Allocated to Hardware Architecture: Compose a hardware architecture comprised of Sensors, Actuators, and Controllers, connected through embedded communication protocols. The goal is to optimize E/E Architecture and create a Software-defined vehicle platform that can be re-used across vehicle programs.

E/E architecture activities are performed at the vehicle system level, according to four independent scopes of responsibilities:

Hardware Architecture
Software Architecture
Communication Matrices
System Mapping

This last activity involves making decisions and trade-offs to ensure consistency between hardware and software, taking communication into account.

As a result, EE engineers are able to deliver optimized architectural proposals to each engineering domain to implement the Hardware (electronics), the Software (Embedded SW) and Electrical (detailed schematics).

Magic Real-Time Communication Designer

Model-Based System Engineering (MBSE) and SysML tools are becoming more sophisticated in order to support the increased complexity of embedded and distributed applications. These new systems are larger, contain autonomous components, operate from the edge to the cloud, and often have strict requirements in terms of performance, scalability, robustness and security.

Two standards - SysML and Data Distribution Service™ (DDS™) - address the necessary end-to-end design requirements for model-based design. SysML defines the requirements of the system itself. DDS addresses the communications requirements between system components running across different computers, including connectivity, security and quality of service (QoS).

Dassault Systemes has addressed the digital continuity and integration between the two worlds of MBSE to interface design with the new Magic Real-Time Communication Designer. This software plugin provides a direct integration to RTI Connext®, the leading commercial software based on the DDS standard, enabling engineers to create model-based systems based on real-time communication flow across embedded and distributed systems. Engineers can go directly from the system model in SysML to RTI Connext for implementation and deployment of a distributed system.

Benefits of this integration include:

Increased productivity by modeling the DDS-related aspects of a system using SysML extended by a DDS-specific profile and generating the necessary DDS setup code in any of the supported Programming Languages.
A graphical, unified representation of the overall system from requirements to functional applications, providing engineers with a common view of the system and a single source of (data) truth.
Integration with RTI Connext to enable graphical design and configuration of all DDS aspects, including Domains, Types, Topics and QoS.

This integration has been specially validated with RTI Connect®, along our partnership with Real-Time Innovations Inc. (RTI).

CATIA Magic (Cameo) plugin for live RTI Connext DDS: publish and subscribe from a SysML simulation

A SysML model can describe a DDS interface. This plugin for CATIA Magic lets it take part in one: a simulation can publish and subscribe to real RTI Connext DDS traffic, so a service that exists only as a model can exchange data with services that already exist as code.The video (linked below) shows the setup and a live demo.What it's forChecking interfaces before implementation.
