Model-Based Systems Engineering (SysML)

Model-Based Systems Engineering (SysML) is the logical capability of describing complex systems with formal, navigable models — using the OMG Systems Modeling Language — instead of (or alongside) prose specifications. It supports requirement, structure, behavior, and parametric views of a system in one coherent model, which downstream disciplines can consume directly.

What it covers

• Requirement diagrams linking text requirements into the model.
• Block definition / internal block diagrams for system structure.
• Activity, sequence, and state machine diagrams for behavior.
• Parametric diagrams for engineering analysis constraints.
• SysML v2 — the next-generation API-first, textual-and-graphical language.

Relationships (see sidebar)

• Supports the Systems Engineering and Requirements Management processes.
• Implemented by systems like Dassault 3DEXPERIENCE (CATIA Magic / Cameo).
• Anchors the engineering side of the Digital Thread.
