Systems Modelling with SysML ( sysml | 21 hours )

Students who wish to attend this course are not required to have any prior exposure to system modelling but should have a solid grasp of “document centric” systems engineering techniques.

This course is offered in two variants to provide a practical understanding of how systems can be modelled using the newest version of OMG's Systems Modelling Language (SysML) specification. The notation and underlying semantics of SysML are explained in a way that allows students to apply what they learn to any suitable system modelling method or tool.
