Clients often ask for examples of Systems Modeling Language (SysML®) applied for Model-Based Systems Engineering (MBSE). This Webel IT Australia site has thousands of pages of examples of applications to many dozens of different problems. Commercial confidentiality often restricts presentation of applications to actual projects, but wherever possible examples here are chosen from realistic problems (such as Wikipedia descriptions of systems).
There is no one worked problem that illustrates every aspect of Systems Modeling Language (SysML®) or Model-Based Systems Engineering. If you are serious about adopting SysML for MBSE, you must take time to explore its many aspects (which, long term, will take you much less time than not using it on a project). Your time investment will be repaid many times over!
In the following, links to examples elsewhere on this site have been collated in themed groups. It is up to you to determine which topics are relevant to you.
