A practical guide for implementing Variability Layer for System Architecture (MBSE)

PLESysMLSystem Architecture 

Let’s start the year with some advanced topics. 👍 

This is the summary of real-world practical use cases, commonly encountered during implementation of the Variability layer in MBSE. The following order for the understanding of the concept is recommended:

  • The fundamentals of variability in MBSE are presented in this CATIA talk:

  • A reference to the documentation is here:

  • When the fundamentals covered above are understood, practical implementation usually necessitates a workable configuration that is summarized in this post below:

Practical Configuration Definition for Model-Based Product Line Engineering (Variability)

 

 

  • In case a product is particularly complex (like a modern car), the architectural definition for the entire product usually proceeds bottom-up. Having a consolidated architectural view on a product level is very important, but maintaining full detail is practically very difficult. The post describes a common solution for addressing this issue. This is applicable irrespective of whether Variability Layer is present, or not:
