Title
An exploration of usage modelling in SysML v2
Abstract
As the Systems Modelling Language (SysML) transitions from version 1 to version 2, it introduces significant advancements in expressiveness, precision, and semantic consistency, particularly in how systems are defined and used. This paper investigates the potential of usage-first modelling, where system behaviour, structure, interaction, and other concepts are represented primarily through usage elements.
Illustrated with a case study, they propose practical criteria to guide practitioners in applying usage-first modelling effectively within SysML v2, contributing to the evolving field of Digital Engineering.
Key takeaways:
- SysML v2 allows for various systems concepts to be represented, with a context layer, hierarchy, behaviour, interfaces, requirements, and design traceability.
- It provides modelling efficacy as fewer elements need to be created, with the containment structure being far more digestible.
- There are, however, inherent limitations in applying it, including the treatment of subsetting and feature typing, as well as some things being better as a library of elements, such as items, as opposed to a single instance.
