Abstract:

To solve the problems in multi-tech system product design such as the low efficiency and frequent reworking as well as iteractive processes,the two-layer design structure matrix(DSM) method was presented.Plastic injection molding machine system design was taken as an example,and the design information was described into two levels to illustrate the optimization principle and assessing criteria. Additionally,the key mission was picked up and the relationship between two layers was built,then accomplishing the transform from complex relationship within coupling missions to simple processing communication.The result demonstrates that the optimization about process planing works with less reworking,simple coupling and clear process.

Key words: multi-tech system product design;two-layer DSM;design process optimization;plastic injection molding machine system design
