Systems Engineering

Systems engineering is a field of engineering that deals with how to research, design and manage complex systems over their life time. It focuses on the whole system and typically involves a number of sub-disciplines including requirements, reliability, logistics, design, testing and maintenance; it requires sophisticated project management techniques.

Systems engineering not only deals with the problem of the system itself but also involves processes, optimization and risk management. Enterprise Architect provides a platform for the system engineer using the Systems Modeling Language (SysML) and model based development, and in addition to the engineering models the tool provides support for project and process management.

SysML Requirements

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

Parametrics

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.

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' option, or
  • Right-click on a Package and select the 'Add | Add a New Model using Wizard' option

The 'Select Model(s)' dialog displays.
