Uncertainty Management in the Concurrent and Collaborative Design based on Generalized Dynamic Constraints Network (GDCN)

This paper describes an uncertainty management method using generalized dynamic constraint networks (GDCN). Uncertainty of parameter in the concurrent and collaborative design is analyzed, and GDCN is presented to manage the uncertainty. Firstly, the model of GDCN including domain level constraints and knowledge level constraints is established. Secondly, the modeling of domain level constraints and knowledge level constraints are introduced; thirdly, the clearing up strategy of conflicts among constraints and consistency algorithm are put forward to gain consistency parameter intervals. Finally, a design example is analyzed to show effectiveness of this proposed method
