Model Based Systems Engineering

Model-based systems engineering (MBSE) is a methodology for systems engineering that uses visual modeling as the primary means of communicating information. Compared to a traditional document-based information exchange, MBSE eliminates the communication of unnecessary information by relying on abstract models that retain only the relevant data. This makes it easier for engineering teams to communicate design intent, understand the impact of design changes, and analyze a system’s design before building it.

In addition to improving communication among engineers and with project stakeholders throughout the System Development Life Cycle, MBSE helps with:

  • Recording intellectual property related to system architectures, designs, and processes
  • Establishing scalable structures for troubleshooting
  • Managing the size and complexity of a project through visual models
  • Evaluating multiple system modifications simultaneously at minimal risk
  • Finding errors earlier in the system development life cycle


Visual Model-Based Languages

Systems Modeling Language (SysML)
SysML is an open standard Architecture Description Language (ADL) that serves as a general purpose visual modeling language for MBSE applications. Other visual modeling languages include:
  • AP233

  • UML 2

  • XMI
