Abstract: To determine the modularity grouping of designers,product structures and design tasks,and to express the unidirectional transmission between cross-domain entities expressed by domain mapping matrix,the concept of inverse domain mapping matrix was introduced to show the reverse transmission.Through integrating domain mapping matrix with inverse domain mapping matrix,domain bi-mapping matrix was established to express the bidirectional transmission of information between different domain design entities.Based on multi-element-tree of correlation,the clustering domain mapping matrix was constructed.By adjusting the selective coefficient of multi-element-tree node,the convergence speed of clustering was accelerated,and the result was more stable and controllable.Combining with collaborative design of ship,the clustering result to modularize domain bi-mapping matrix of designers and product structure was satisfied.
