The Systems Modeling Language (SysML) is a general-purpose modeling language for systems engineering applications.
SysML supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems.
SysML is based on UML (Unified Modeling Language) and replaces the modeling of classes and objects by block modeling for a vocabulary more suited to System Engineering. A block encompasses all software, hardware, data, process, and even people management concepts.
The advantages of SysML over UML for systems engineering become obvious when considering a concrete example, like modeling an automotive system. With SysML you can use Requirement diagrams to efficiently capture functional, performance, and interface requirements, whereas with UML one is subject to the limitations of use case diagrams to define high-level functional requirements.
Additionally, with SysML you can use Parametric diagrams to precisely define performance and quantitative constraints like maximum acceleration, minimum curb weight, and total air conditioning capacity.
UML provides no straightforward mechanism to capture this sort of essential performance and quantitative information.
Analysist report that SysML also offers systems engineers several noteworthy improvements over UML, which tends to be software-centric. These improvements include:
- SysML’s semantics are more flexible and expressive
- The requirement diagram can be used for requirements engineering
- The parametric diagram can be used for performance analysis and quantitative analysis.
