Product modeling beyond information

The authors introduce a new method for the establishment of an extension to current product models in order to enhanced communication between human and modeling processes. The main contribution of the reported work to product modeling is a dialogue input and model representation of human intent in order to make assistance for human who applies product model and needs important details from thinking process of human whom decision must be considered. The proposed method enforces human intent based definition of engineering objects. In order to achieve this, human intent representation is used at definition of engineering objectives for definition of engineering objects while contextual connections amongst intents, objectives and decisions, and amongst these entities and engineering objects are also considered. Consequences of changes of engineering objects are tracked along change chains in the change affect zones of the changed engineering objects. This modeling constitutes a new extension to classical product modeling and is placed between the human and the current information based product model in order to establish an efficient and coordinated control of engineering object parameters.
