Abstract: By introducing data flow diagram(DFD) in software design into information modeling for engineering design process, this paper proposes a novel and powerful approach to information modeling and re-engineering which is based on DFD and Design Structure Matrix (DSM) after analyzing the existing modeling techniques comprehensively. A new tearing algorithm is presented . The realization of this approach is demonstrated by an injection mold design case.

Key words: design structure matrix, information modeling, re-engineering, data flow diagram
