英文摘要：

This paper analyzes the characteristics of the enterprise-cluster manufacturing system and proposes an open modular product design methodology by dividing the producing technologies into technology ceils and by selecting the most valuable technology module. In the proposed methodology, a reasonable technology division is realized by the structure-mapping function based on technologies and by the technology cell clustering based on the design structure matrix （DSM）. Moreover, the selection of a valuable technology module is implemented by the relational analysis of technology modules based on a quantified DSM （QDSM） and by the evaluation of the importance of technology modules. Thus, an open modular product design methodology is presented, which is finally applied to the design of a plastic injector with open modular structure for enterprise-cluster manufacturing.
