Constraint Information Visualization Methodology for Cooperative Design

摘要

It is difficult to manage constraint information in cooperative design due to its variety and changeability. The concept of Constraint Information Visualization (CIV) in cooperative design and CIV framework comprising the CIV methodology are put forward to control cooperative design flow efficiently, detect constraint conflicts early and negotiate the contradiction under the support of visualization. On the basis of classification and representation of constraint information, this paper discusses the importance of CIV and its formalized description for cooperative design. The procedure of visual mapping and harmony evaluation is given in details. The main step of visual mapping is divided into classification mapping, structure and harmony mapping and detailed property mapping. Visual Mapping implements mapping from constraint information to visual representation with corresponding mapping modes. The concepts of local harmony and global harmony are also proposed for cooperation. An application of CIV verifies CIV methodology, which will direct a new way to implement complicated constraints management in cooperative design.
