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 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. The book covers * Variant Modeling Concepts * Method for Variant Modeling with SysML (VAMOS) * Variant Stereotypes for SysML * Example: Forest Fire Detection System * Example: Virtual Museum Tour
