近年來資訊科技與網路技術的快速發展，傳統產品的開發產業，紛紛導入電子化的資訊系統，並且能透過資訊系統的整合，達到公司內外部的有效管理；但是往往忽略了導入電子化系統的目的，不只是幫助公司做好有效的管理，同時也是建立了良好的電子化環境，所以本研究能夠以電子化的系統為基礎，透過資訊科技的整合，達到知識管理與智慧型決策才是電子化的最終目的。
而本文運用知識管理的流程架構，建立在產品的開發流程上，從知識創造、知識來源、知識分類、知識學習與知識運用等五個部份作為知識管理的流程，並且結合產品資料管理系統內的工程流程引擎，作為知識的主要來源；之後運用產品在開發過程中，所累積的資料，進行產品案例庫的建立，並且透過案例式推論，進行案例庫內案例知識的擷取，作為新產品開發時在產品設計與製程參數設定的決策依據；最後運用工程流程引擎所累積的工程知識，進行工程知識庫的建立，解決開發流程中所產生的問題，並且透過失效模式與效應分析的方法，達到設計流程與製造流程問題預防的效果。
對於研究內將知識管理建立在產品開發流程上，主要增加產品設計者對於設計外型的參考與設計時程上的評估，有著有效的搜索機制；另外製程參數的設定者，不會因為知識經驗的缺乏，產生參數設定的不當，造成成本上的浪費；至於工程知識庫的建立，以達成問題診斷與問題預防為目標，最後以縮短產品的開發時程為最終目的。

Recently, with the fast development of internet technology, traditional production development industry gradually implants electrical information system. Through the integration function by electrical information system, it becomes easier to manage, and eventually helps the users achieve knowledge management and make intelligent decisions.
The framework of knowledge management processes builds upon the product developments. Knowledge source, knowledge creation, knowledge classification, knowledge learning, and knowledge application are the keys to knowledge management. The combination of knowledge management and the workflow in product development management system is our major information source. And then we use those gathered data during the product developments to create a product database. We also can access the data through Case Base Reason, which can be used for decision authority during the product design and process parameters. Lastly, by using the process engine we can turn the experiences we gained into a knowledge database to resolve the problems in the development process, and through FMEA to achieve preventing problems in the design and production processes.
Implanting the knowledge management helps the product designers having more thoughtful consideration in exterior design and timing design while designing new products by its efficient search option. In the other hand, new designers can avoid extra cost due to parameter setting error. Overall, the implant of knowledge database can provide diagnosis and precaution to development problems, and finally save time in product development process.
