In the Model-Based Systems Engineering (MBSE) approach, models are created to deal with complexity. In doing so they allow systems engineers to understand an area of interest or concern and provide unambiguous communication amongst interested parties.

Over the past 13 years MBSE has become widely adopted by systems engineers as part of a long-term trend toward model-centric approaches adopted by other engineering disciplines, including mechanical, electrical and software.

In particular, MBSE is expected to completely replace the document-centric approach that has been practiced by systems engineers in the past and to influence the future practice of systems engineering by being fully integrated into the definition of systems engineering processes.

MBSE’s surging popularity is due to several factors, including:

  • Improves communications among stakeholders and engineers
  • Increases productivity
  • Improves quality
  • Reduces risks by better defining cost estimates

There are a multitude of modelling techniques and approaches that fall within MBSE. These include:

  • Structured Analysis and Design
  • Data Flow Diagramming
  • State Transition Diagramming
  • Behavioral Modelling
  • Entity Relationship Modelling
  • Finite Element Modelling
  • Environment Virtualization
  • Computer Aided Design (CAD)
  • Analytical Modelling
  • Process Modelling

Modeling has always been an important part of systems engineering to support functional, performance, and other types of engineering analysis. Wayne Wymore introduced a mathematical foundation for MBSE in his book entitled “Model-Based Systems Engineering” in 1993.

However, the growth in computing technology and the introduction of modeling standards such as SysML, UPDM, Modelica, HLA and others, are helping to enable MBSE as a standard practice, and provide a foundation to integrate diverse models needed to fully specify and analyze systems.

Want to learn more about MBSE? Tonex offers Introduction to Model-Based Systems Engineering (MBSE), a 2-day course where participants will learn how MBSE is applied and how modern system engineering uses models to create structural and dynamic artifacts for conops (concept of operations), system requirements, design, architecture, analysis verification and validation activities. 

Additionally, Tonex offers more than a dozen other courses in MBSE training, including:

MBSE Training Crash Course (4 days)

Model Based Requirements Engineering  (4 days)

SysML Training Crash Course (4 days)

Requirements Engineering Workshop with Use Cases (3 days)
