縮短新產品開發專案的時程為現今設計鏈之研究趨勢，藉由最佳化新產品開發之流程，減少不必要的資訊遞迴以達成時間之減省，設計結構矩陣(DSM)為一有效之管理工具，DSM以往被應用於新產品開發專案之管理。 然而，由於資訊科技發達，新產品開發之型態逐漸由傳統面對面溝通演變為透過網路進行協同設計，跨公司的設計協同模式(CCDC)應運而生；在此模式下，新產品開發專案的複雜度相對提高，參與設計的專案成員散佈在世界各地。設計結構矩陣也無法適用於跨公司設計協同模式上，基於此原由，本研究以跨公司設計協同之流程為標的，發展一延展式設計結構矩陣(E-DSM)以應用於協同設計流程之管理。 The new product development (NPD) is coming to a new phase, cross-company design collaboration (CCDC), which is involving more than one enterprise to co-develop a new product. Collaborative design processes are an instrument which has been used in several industries. The design and development of complex engineering products require the efforts and collaboration of hundreds of participants from diverse backgrounds resulting in complex relationships among both people and tasks. Though the past studies have proposed a useful tool –Design Structure Matrix (DSM) to model the NPD process, however DSM focuses on the cross-functional interaction but rarely emphasizes on modeling a clear and understanding CCDC process model, this thesis proposed a new type of DSM which extends the traditional DSM from applying in cross-functional development to a higher level- CCDC, called Extended-DSM (E-DSM) to fill in the vacancy. In this thesis we first introduce the thesis background and motivation, then chapter 2 focuses on survey in two areas, includes new product development, business process re-design techniques. In chapter 3, we have an overview of CCDC, and introduce the design structure matrix, the main methodology we according to and use in E-DSM. Chapter 4 represents the main methodology we proposed- E-DSM, and we also apply it to an example of development of pneumatic control system. Finally, the conclusion and future research suggestions are made.
