The Application of Constraint Satisfaction Technique in Conflict Detection and Resolution

The conflict detection and resolution in collaborative design is a key issue to maintain multidisciplinary design consistency,This paper proposes a new method for conflict detection and resolution based on constraint satisfaction technique.The representation of design constraint,the interval arithmetic of the constraint satisfaction problem CSP and the conflict resolution strategy based on constraint relaxation and adjustment are introduced.A constraint-satisfaction based conflict detection and resolution tool CSCDR is then developed.It can help collaborative designers to detect and resolve the conflicts in time in the early stage of the design process so that the unnecessary design iteration and repeated negotiation are avoided and the design efficiency is then much improved.A design case illustrates the effectiveness of CSCDR.
