System Modelling with SysML — A 3 day course
The Systems Modeling Language (SysML) is the OMG standard for supporting Model-Based Systems Engineering (MBSE). The SysML provides a number of diagrams, and elements which address the needs of expressing the structural and behavioural characteristics of a system as well its requirements and constraints.
This course guides delegates though the application of modelling concepts in SysML through its application to typical system engineering problems utilising each of the SysML diagrams.
This course provides a practical understanding of how systems can be modelling using the OMG's Systems Modeling Language (SysML). The notation and underlying semantics of SysML are explained using practical examples so that delegates can apply what they learn to any suitable system modelling method or tool.
What The Course Doesn't Cover: Model-Based System Engineering Processes and Methodologies.
- To understand the principles of system modelling

Systems Engineers who need to be able to construct SysML models during the analysis and/or design phases of a project that is utilising a model-based systems engineering approach.
Delegates 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.
The course does not require the use of a computer, as all the SysML diagrams can be produced by hand. Some delegates may wish to gain experience in using a suitable tool or in which case each delegate will require a machine. If you prefer to use open source or trial software, contact our technical staff to discuss the options.
