Study Notes

SysML Overview

SysML is an extension of the Unified Modeling Language (UML).
It has 4 categories of 9 diagrams.
SysML V2 is under specification and includes textual annotations.

SysML Characteristics

SysML does not provide guidelines or recommendations for the modeling process.

Systems Engineering

Systems engineering involves asking "Why is this system needed?", "What is the best solution trade-off?", and "How to build this solution?".
It involves requirements modeling, architecture models, test units, and realization of hardware and software components.

Modeling

Modeling involves collaboration, decision-making, and traceability.
It involves requirements analysis, rationale, and performance estimates.

SysML Language

SysML is a graphical modeling language for specification, architecture, high-level design, analysis, verification, and validation of systems.
It involves requirements, structure, behavior, and parameters.

SysML Diagrams

SysML diagrams include block definition diagrams (bdd), activity diagrams, requirements diagrams, and requirements tables.

Modeling best practices

Modeling requires the right level of abstraction and the right viewpoints.
It requires a rigorous and explicit formalism.
