Model-Based Systems Engineering (MBSE) is the practice of developing a set of related system models that help define, design, analyze, and document the system under development.

These models provide an efficient way to virtually prototype, explore and communicate system aspects, while significantly reducing or eliminating dependence on traditional documents.

MBSE is the application of modeling systems as a cost-effective way to explore and document system characteristics. By testing and validating system characteristics early, models facilitate timely learning of properties and behaviors, enabling fast feedback on requirements and design decisions.

Although models are not a perfect representation of a system, they provide knowledge and feedback sooner and more cost-effectively than implementation alone. And they allow simulation of complex system and system-of-systems interactions with appropriate fidelity to accelerate learning.

In practice, engineers use models to gain knowledge and to serve as a guide for system implementation. In some cases, they use them to directly build the actual implementation (e.g., electrical CAD, mechanical CAD).

Structure, behavior, and operational characteristics of system elements are explored by models. They are also used to evaluate design alternatives, and validate assumptions faster and earlier in the system life cycle.

All this becomes even more apparent for complex systems like medical systems, aircraft and even satellites. In other words, MBSE excels where the solution must be proven practical beyond all possible doubt before.

Additionally, models also communicate and record decisions that will be useful to others. This is crucial information which basically serves as information for compliance, impact analysis and other needs.

Want to learn more? Tonex offers MBSE Training, a 3-day course that covers the formalized application of modeling to support systems analysis, use cases, requirements, design, analysis, verification and validation activities. MBSE Training also covers the process that begins with the conceptual design phase and continues throughout development and later life cycle phases.

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

Model Based Testing Training (3 days)

Model Based Requirements Engineering  (4 days)

SysML Training Crash Course (4 days)

Requirements Engineering Workshop with Use Cases (3 days)
