PhD Thesis |
Resumé Feature modeling has the ability to associate functional and engineering information to shape information in a product model. Current feature modeling systems, however, are still rather tied to techniques of conventional geometric modeling systems, offering limited facilities for defining feature semantics, and failing to preserve this semantics as the feature model evolves.
This thesis presents a new feature modeling approach, called semantic feature modeling, which provides a declarative specification scheme for the semantics of feature classes. In addition, this semantics is correctly maintained for all features in the model, throughout the modeling process. The validity maintenance scheme for this monitors each modeling operation, assessing the conformity of all features with their validity criteria. A validity recovery mechanism provides explanations and context-sensitive hints aimed at overcoming each invalid situation detected.

Thesis propositions
Well, in The Netherlands, PhD theses are accompanied by a list of propositions. Their purpose, at least in theory, is to give the candidate the opportunity to expose and defend his ideas in various fields, not necessarily technical or scientific.
