Constraint-based feature validation

Abstract

The feature modeling paradigm combines geometric and functional product information in one model. In an ideal product development environment, multiple views of a product in terms of features coexist. Feature validation concerns the validity of the feature information in all these views, focusing on validity specification and maintenance. This thesis presents a feature validation scheme based on constraints. It enables flexible and expressive feature validity maintenance. The scheme ensures that only meaningful products can be specified, and that their validity is maintained under product modifications from different views.
