摘　　要：对软件工程中的数据流图 (DFD)加以改进 ,用扩展的数据流图来描述复杂的设计流程 ,并建立设计信息模型 ;通过对信息模型进行分析、评估获得当前最优的信息模型 ;然后将信息流映射为设计结构矩阵 (DSM )来进行信息模型的重组。深入讨论了扩展数据流图和设计信息流 ;对目前尚不很成熟的DSM的割裂算法进行了探讨 ,并给出了相应的算法流程 ;同时 ,结合工厂生产设计流程进行了详细的分析。Extended data flow diagram (EDFD),which is achieved by improving data flow diagram (DFD) used in the software engineering,is proposed to represent complex design flow and construct its information model. The optimal information model is selected from several existing models,which are obtained through analyzing the design information model. Then the reengineering of the information model of design process is implemented by mapping the information flow into DSM(Design Structure Maxtrix) and using the methods of DSM. In addition,EDFD and design information flow are discussed deeply. Through analyzing and discussing the existing imperfect tearing algorithm of DSM,a corresponding algorithm is presented. At the same time,a case study about the production and design flow in a factory is employed to illustrate the whole process in detail.
