SysML

SysML does not provide explicit built-in language constructs to model variants. Nevertheless, SysML is useful to create a model for variants. The VAMOS method presented in the book Variant Modeling with SysML is one option on how to model variants with SysML. It uses the profile mechanism of SysML to extend the language with a concept for variant modeling. The concepts are core, variation point, variation, variant, variant constraint, and variant configuration. The book shows how to apply the concepts with standard SysML modeling tool.
