Variant Modelling - Approach?

[stewartd]

Hi there,

NoMagic Cameo System's Modeller seems to come with basic support for variant modelling. In particular, you can define variation points using standard SysML generalisation relationships, then create an instance model - which launches a wizard - and allows for selecting the appropriate parts, capturing the result in a new diagram.

Then, you can view the result as a tree-style diagram (Instance Map), which is akin to a basic feature model.

A quick overview of the process is here:

The question is: how can I replicate this in EA?

Hi,

you may create your own MDG to model feature models.

For example make a <<vp>> stereotype and your own shape for a 'Variation Point'.

Somewhere in the net there is an example you can download. There is also a book which describes modeling of variants.
