Abstract: To deal with the problem of definition and expression of correlation in collaborative design, organizational characteristics were analyzed based on district collaborative design space. The connection relationship acyclic graph by adding connection semantics was achieved, and the correlation features and connection modes were explained. After constructing correlation information model, the algorithm was proposed to solve correlation for district collaborative design, And the correlation management model based on Product Data Management (PDM) was also proposed. Finally, a case study was provided to illustrate practicability of the above-mentioned theories and methods.

Key words: district collaborative design, correlation relationship, network graph, information model, product data management
