Information model of correlation for district collaborative design

The district collaborative design was an advanced design organization mode.The problem of how to establish the information model of correlation for district collaborative design was aimed.The correlation meta-model was designed based on multiple views description of district collaborative design.The method,which was used to enhance constraint semantics,was put forward under analyzing the relativity of correlation condition,and the mapping relation between the graph of connection and the graph of correlation was conducted to achieve the information model of correlation.Finally,the platform for district collaborative design was developed,and a case study was conducted to prove these theories and methods.
