2. 15/09/20092 Carlos Roberto Marques Junior © LES/PUC-Rio Staged Configuration A Feature Model describes the configuration space of a system family. The process of specifying a family member may be performed in stages. In each stage, some configuration choices are done. Resulting in a subset of the initial Feature Model This Process is called Staged Configuration.

3. Configuration vs. Specialization Configuration –consists of the features that were selected according to the variability constraints defined by the feature diagram. –The relationship between a feature diagram and a configuration is comparable to the one between a class and its instance in object-oriented programming. Specialization –is a process to transform a feature diagram and yields another feature diagram, such that this last diagram denotes a set of configurations that is a subset of the first one. –A fully specialized feature model denotes only one configuration. 2/17/20143 Carlos Roberto Marques Junior © LES/PUC-Rio

4. Staged Configuration The need for staged configuration arises in at least three contexts: –Software Supply Chains; –Optimization; –Policy Standards 15/09/20094 Carlos Roberto Marques Junior © LES/PUC-Rio

6. 15/09/20096 Carlos Roberto Marques Junior © LES/PUC-Rio Optimization Staged configuration offers an opportunity to perform optimizations based on partial evaluation. When certain configuration information becomes available at some stage and it remains unchanged thereafter, the software can be optimized. For example, configuration information available at compile- time can be used to eliminated unused code. Optimizations are especially interesting for embedded software and software that need to be distributed through a network connection.

9. Proposal Use a Multi-Agents approach to help the stakeholders to configure the feature model. Study techniques to resolve conflicts where there is some dependencies between features. Extend the work from static configuration to dynamic reconfiguration. 2/17/20149 Nome do Autor © LES/PUC-Rio
