摘要：This paper analyzes conflict features in architecture pipe routing,and builds a pipe routing design conflict model by taking into account of discrete nominal internal diameter selection of pipes,material costs,and conflict solution *** pipe routing as an assembling process,a conflict detection approach for pipe routing in collaborative architectural design is proposed based on an aforementioned *** network is used to describe the relationship among pipe routing design parameters and constraints;design conflicts are detected by matching designers' input and constraint network;and detected design conflicts are reordered according to the number of pipe parameters in *** order to support the collaborative requirement of pipe routing design,a prototype system using browser/server architecture is *** illustrative example of water pipe routing in a room is used to show the effectiveness and efficiency of the approach.
