Webel IT Australia has tracked nearly every inch of the development of the new SysMLv2 language version for next-generation Model-Based Systems Engineering (MBSE), and already offers training and consultancy for applications of SysMLv2.
SysMLv2 is a major evolution of the language, with some new terminology, some new modelling elements, some new notations, a Web Services API, and a powerful new textual representation modelling code. However, there are meta-principles for modelling and organising projects that go way beyond a specific language specification, and principles that go beyond tools. THAT is what we do best, the "art and science" of graphical engineering and systems thinking!
Some key features of SysMLv2 for next generation MBSE include:
- Based on the new KerML specification instead of UML.
- Has a new textural representation modelling code, a major innovation that is already making SysML more accessible and popular for MBSE.
- Has a new vendor-independent Web Services API for teamwork and model queries (SysMLv2 as a new very powerful cloud database technology).
- Better integration of Requirements with the wider SysML model, and improved propagation of quantitative Requirements across the model.
- Improved integration of state and action behaviours with the wider model.
- New mathematical calculations system (building on the previous powerful and popular SysMLv1 Parametrics technology, but now fully integrated at all levels of the model and supported by KerML expressions and function libraries).
- Optimal support for simulation capabilities built-in from the get-go!
- New more consistent element naming pattern.
- Improved Part Definition system (replaces the Block) with support for progressive Part Usage "on-the-fly" redefinitions for more powerful systems structure modelling and systems configuration and modes modelling.
- Easier handling of property redefinitions and new notations for more powerful and flexible systems hierarchies.
- Reified relationships with improved semantics.
- Improved handling of object/instance-like items and flows for signals, data, and physical quantities.
- Improved handling of values and quantities with units.
- Improved lifetime modelling.
There is also a trend towards more generative diagramming, and of course, very active work on leveraging Natural Language Processing to create SysMLv2 models and diagrams.
