Constraint-Based Conflict Detection and Negotiation in Collaborative Design

The conflict problem in collaborative design was studied from the view of Constraint Satisfaction Problem (CSP). A hierarchicalmodel, which includes product level, component level, part level and domain level, was presented for the management of constraint network. Constraint verification and interval propagation algorithms were proposed to detect the conflicts. Several algorithms for generation of conflict negotiation suggestions based on backtracking and constraint relaxation strategies were put forward. A Web-based prototype system was constructed to help the designers detect and negotiate the conflicts.
