Abstract


Collaborative design multiple design teams together to complete the process of a product development project through the division of labor and collaboration. These teams located in different geographical areas of knowledge, between them there are a lot of mutual restraint, mutual influence relationship, and they consider the point of view of product development, evaluation criteria, and knowledge areas vary; same time, the design object or property also exist between various interdependent relationship. Therefore, in the collaborative design process inevitably conflict. Conflict plays an important role in the collaborative design process, on the one hand the existence of conflict will inevitably lead to the design of the lack of coordination, and even stranded; On the other hand, the conflict is a good or the beginning of the innovative design, with the continuous settlement of the conflict, a better design also will be generated. Therefore, the co-design the study of the problem of conflict management has a very important and positive. Processing of conflict detection and elimination technology, the main work is as follows: (1) design conflict in collaborative design process, collision detection based on relational database technology, and the technology-based application system structure and implementation methods. (2) a hierarchical object the - constraint information model, and to study the expression of the model using XML and relational databases. (3) digestion technique on the basis of the conflict based on case-based reasoning, its reasoning strategy is proposed based on rough set conflict digestion case-based reasoning strategy. The strategy is through the use of rough set theory and methods, examples Knowledge Base for processing, in order to gain examples of each characteristic the attribute weights and the index of the case library. (4) to study the process of knowledge base processing based on rough set examples, methods, and algorithms. And through the analysis of an instance of the application, the effectiveness of the strategy. Of hierarchical object - the constraint information model can be effective expression object information and its relationship with design constraints, dig library research XML and relational expression of the model used to build the Web project database to accommodate collaborative design network environment information sharing and interaction needs, and conflict detection. More difficult to effectively guarantee the reasoning results based on rough set of conflict resolution the use of examples of strategies to overcome the shortcomings in the traditional strategy, which need to rely on experts in the field of knowledge and experience manual to determine the weight and the specified index, and the resulting maximum correlation issues.
