Model-Based Engineering (MBE) is a technical approach to modeling that integrates the functional, structural, and performance capabilities of a product or system during its life cycle
. Models are used as an integral part of the engineering foundation and include requirements, analysis, design, and implementation
and verification of system characteristics. Modelintegration is about implementing the verified capabilities of a system.
In model-based systems engineering, a model is a simplified, understandable version of a concept, phenomenon, relationship, structure, or system. Such a model may be represented in graphical, mathematical, or physical form and is intended to facilitate understanding of the functional interaction of the model components. In addition, the model can be used to explain, control, and predict events
and assist system managers in making decisions. Through the structures represented in the model, development teams can better understand the impact of design changes, communicate the objective of the development in an understandable manner, and analyze the system design prior to construction. The aspects of Model-Based Engineering (MBE) specifically associated with systems engineering are implemented in Model-Based Systems Engineering (MBSE).
