Handling complex configurations?
‣ Considering variability by concerns
‣ Managing constraints between variability models
‣ Allowing the user to dynamically create sub-configurations
‣ Allowing to create links between sub-configurations
‣ Ensuring consistency in user’s choices
‣ Supporting a flexible configuration process

+ inter-FM constraints
SPLC’14 - Florence September 2014
Inter-FM constraint
• Association contains oriented functions
• Function contains rules
• Rule:
• from a source FM to a target FM
• state implies action
• state: selected and excluded features
• action: select, exclude, add new CT constraint

Propagation Algorithm
• Hypothesis: the SPL is consistent
‣ Incremental algorithm based on biconnected components
• Always terminate
• Always reduce the solution scope

Future Work
• Formalize the whole approach (ongoing)
• Improve the expressiveness of domain model
• Allow constraints on the model
• Support undoing actions
• Industrialize our case study:

SPLC’14 - Florence September 2014
Thanks for your attention!
‣ Tooled approach
‣ Design a SPL with several FMs
‣ High level abstraction of the domain
‣ Flexible derivation process
‣ Ensure consistency of the configuration
‣ Validated on a real system
