A step by step guide to creating your first Systems Engineering Model

Get started with SysML with this introduction to the MDG Technology, available toolboxes and more

The SysML Requirements Model provides the system requirements, the expected abstract behavior, and the operating constraints that the designed system must conform to.

SysML Parametric models support the engineering analysis of critical system parameters, including the evaluation of key metrics such as performance, reliability and other physical characteristics.

Usage

To model Systems using SysML in Enterprise Architect, you work through the following steps:

·Create a Systems Engineering model to develop your system
·Create a Requirements model to define the systems requirements and expectations
·Create an Operational Domain model, which describes the environment that the system operates within, and the entities it interacts with
·Create Constraint models to describe the systems operating characteristics using parametric models
·Simulate the parametric models to verify their correctness and obtain the desired characteristic
·Design the system's composition using SysML Blocks and Parts
·Implement the embedded software using UML Classes and behavioral models
·Create a Library of reusable SysML blocks, representing subsystems that can be reused on other projects, and other common Type definitions

In the Project Browser, either:

·Click on the New Model From Pattern icon in the toolbar
·Right-click on a model root node and select the Add a New Model using Wizard context menu option, or
·Right-click on a Package and select the Add | Add a New Model using Wizard context menu option

 

The Select Model(s) dialog displays.
