Research On Browing And Annotating About Graph In Collaborative Explore For Product

Computer Supported Collaborative Design (CSCD) has become the current hot research in the field of information technology. This paper studies browsing and annotating technology in the process of product collaborative design, which focus on the trait of data heterogeneity, need variety and process repetition. First of all, based on the concept model of CSCD, the paper introduces key technique of CSCD system, sets up the application environment model of system platform and designs the hierarchy of CSCD system.Secondly, focus on different levels of demand in the co-browsing for products, product integration model hierarchical structure is designed based on feature core structure. Introducing the neutral feature operation, this text puts forward to the program of model transformation based on feature operation. For displaying quickly of the product model, the program of lightweight display for the product model in the basis of information decomposition is proposed.Then, by analyzing the process of co-annotating, the text designs asynchronous co-annotating mode based on collaborative theory of task management.Based on that, the abstract model of collaborative annotating members is set up, also the method of two-level decomposition and double selection priority scheduling policy for the co-annotatng task which based on resource optimizing are proposed.In the basis of shared model, the use of extended event-driven process chain(eEPC), the text establishes process models of co-annotating.Finally, based on the CSCD platform, adopting the technologies of ObjectARX and MFC, the browsing and ann otating function of DWG document is implemented, and the partial function running examples of DSCD system platform are shown.
