Variant Modeling with SysML

MBSE4U Booklet Series

About the Book

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.

Table of Content: 

  • Introduction
  • Variant Modeling Concepts
  • Variant Modeling with SysML
  • Other Variant Modeling Concepts
  • Variant Stereotypes for SysML
  • Example: Forest Fire Detection System
  • Example: Virtual Museum Tour 

Print version is available at Lulu or Amazon.

Tim is a member of the executive board of the German consulting company oose, a consultant and trainer, lecturer of master courses, publisher, book author, and active member of the OMG and INCOSE community.

Tim has written sections of the initial SysML specification and is still active in the ongoing work on SysML v1, and the next generation SysML v2.

He is involved in many MBSE activities and you can meet him on several conferences about MBSE and related topics.

As a consultant he has advised a lot of companies from different domains. The insights into their challenges are one source of his experience that he shares in his books and presentations.

Tim has written many books about modeling including Systems Engineering with SysML (Morgan Kaufmann, 2008) and Model-Based System Architecture (Wiley, 2015). He is the editor of the pragmatic and independent MBSE methodology SYSMOD – the Systems Modeling Toolbox.
