Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
Design process is dynamic and uses an important number of models during its progress. CAD (Computer Aided Design) models and CAE (Computer Aided Engineering) are used during design and an important number of interactions must be mastered between the different models of the designed system to be robust and in accordance with initially defined specifications. An important number of works exist on the link between digital mockup and analysis models. However design/analysis integration must take into consideration the models multiplicity (digital mockup and simulation) due to model evolution in time, but also to system engineering. To manage the modifications on the system, and the V cycle, the dependence links between the different models must be known and the nature of the modification must be characterized to estimate the impact of the modification among dependent models. We propose to describe the nature of a modification and by consequence to help to know the necessity to spread in other models and the way to qualify modified information. For this, a metric is proposed allowing to qualify/evaluate data/information, based on the maturity and validity of information and models.
