“…Conceptual structures are a graphic system for representing concepts and relations that is general as predicate calculus. There have been studies on the use of conceptual graphs for various CAD-related topics such as: mapping the enterprise information language EXPRESS (Wermelinger and Bejan, 1993), modeling object features and constraints for CAD (Salomons et al, 1994), and modeling the knowledge interchange format KIF . In contrast to these and other capabilities, conceptual graphs do not represent uncertainties well.…”

This paper describes the development of computational support tools for practically successful engineering techniques. The paper reviews the requirements for manual Quality Function Deployment techniques, presents them, and discusses their limitations. It argues that computational support tools can alleviate most of these limitations and that a graph-based information representation for such techniques is an excellent choice for supporting both QFD techniques and their integration with other external CAD-related computational services. The paper presents an architecture for a computational QFD (CQFD) tool based on the graph-based modeling environment n-dim. It shows how this architecture supports most of the requirements for QFD techniques, in addition to providing many additional functionalities, and briefly illustrates how the CQFD tool will be used.

“…According to Giguère et al [1], a technological link is a link expressing a dependency relationship between information items. In the context of an assembly, many authors ( [2][3][4]) use the term Mating relation to describe a dependency between two components of an assembly. To describe the type of dependency more precisely, they use the term constraint.…”

CAD systems have undergone enormous progress. They are becoming more and more intelligent and automated. But mechanical products are also more and more complex. which makes their management more delicate, and especially the management of associations and the propagation of changes affecting one of the components in systems designed using Computer-Aided Design software’s. Therefore, to propagate this change easily, it is important to predict the Change Propagation Path. In this context, this paper focus on a mothed based on establishing correspondences between the assembly Components features to facilitate the associations reconciliation and then change propagation. Thanks to this method, by specifying the affected features in one component, it is easy to predict which other features (in other assembly parts) are likely to be affected too. To this end, the authors proposed an Association Reconciliation Algorithm as well as a Correspondences Algorithm which are mainly based on the assembly mates, the topological and geometrical relationships existing between components. The results of those algorithms will be used later one to determine the change propagation paths and the change propagation tree.
