Systems Modeling Language (SysML) Seminars

Systems Modeling Language (SysML) Seminars: Systems Modelling Language (SysML) is a general purpose modelling language for engineering systems best known for its graphical representations.

These representations, or diagrams, are based on a semantic foundation for modelling system behavior, requirements, structure, and parametrical elements which are used to integrate with other engineering analysis models using the OML XML Metadata Interchange.

There’s often much confusion over Unified Modeling Language (UML) and SysML. The modeling language that came first was UML but tended to be software-centric. SysML is generally defined as an extension of a subset of the UML because it still uses UML’s profile mechanism. In fact, seven of SysML’s nine diagrams come from its parent modeling language. Even so, SysML offers systems engineers some definite improvements over UML.

These include:

  • SysML allocation tables support common kinds of allocations. Whereas UML provides only limited support for tabular notations, SysML furnishes flexible allocation tables that support requirements allocation, functional allocation and structural allocation. This capability facilitates automated verification and validation (V&V) and gap analysis.
  • SysML’s semantics are more flexible and expressive. SysML reduces UML’s software-centric restrictions and adds two new diagram types, requirement and parametric diagrams.
  • SysML is smaller and easier to learn than UML. Since SysML removes many software-centric and gratuitous constructs, the overall language is smaller as measured in diagram types (9 versus 13) and total constructs.
  • SysML model management constructs support the specification of models, views, and viewpoints that are architecturally aligned with IEEE-Std-1471-2000.

Both the definition and maintenance of UML and SysML are overseen by the Object Management Group (OMG), which describes itself as an international, open membership, not-for-profit technology standards consortium, founded in 1989.

OMG standards are driven by vendors, end-users, academic institutions and government agencies. But the most important aspect is OMG oversees the definition and maintenance of UML specifications. This oversight gives engineers and programmers the ability to use one language for many purposes during all phases of the software lifecycle for all system sizes.

While both modeling languages are utilized, from a systems engineering perspective, SysML is the more useful because it involves modeling blocks rather than the modeling classes of UML.
