在產品形成及使用週期中,因客戶使用時所產生的問題回蝕至售後服務、市場、採購、製造、通路等部門,可整理出與產品相關的屬性,再對應到與研發設計相關的屬性,進而轉成設計規則的知識,使新產品功能快速反應客戶之需求。本研究擬建立一個以web-based智慧型代理人的產品形成及使用週期問題回饋的架構,容許上中下游產品開發、製造、運籌及使用者在各地回報問題,並經一套智慧型分析系統以期能: 1.迅速找出問題原因,解決問題; 2.累積經驗建立狀況處理程序,因而能適切而迅速解決問題; 3.記錄問題發生源頭,釐清責任,以為績效管理之助; 4.就自動分類歸屬後結果,儲存成知識型資料庫,以便可再利用; 5.回饋及分析問題至設計源頭以建立避免再發生同樣問題之機制,經驗的累積亦可轉化成設計規則,而提昇設計者之能力和對問題的敏感度。 本研究的貢獻包括:(1)建立一個產品形成及使用週期之下游問題回饋架構;(2)針對模糊徵狀的產品問題,利用模糊決策樹方法,能夠自動判斷歸屬原因。
In the product forming and usage life cycle, the problems found by customers can be passed to the service, market, procurement, manufacturing and channel departments to generate the product related attributes. These attributes can be further linked to product design attributes, and then be used to produce knowledge of design rules. Through this feedback process, the functions of the new product can quickly meet the customer demands. The purpose of this paper is to develop a web-based automated problem analysis and feedback management system for product forming and usage life cycle in order to accumulate problems and experience throughout the various stages of supply chain: 1. Quickly locate the cause of the problem and re-solve it; 2. Accumulate problem solving experience to make ”Out-of-control action plans” so that future problems can be properly and quickly resolved; 3. Track the problem and clarify the responsibility for efficient performance management; 4. Store to knowledge database from solving experience in order to reuse; 5. Accumulate experience and feedback to design origin so that mechanisms such as design guidelines/checklist can be developed to prevent problem reoccurrences in the future. The contributions of this paper include: (1) Establish an integrated feedback framework for the product forming and usage life cycle; (2) Propose an automatic cause identification methodology for product problems with fuzzy symptoms by using the fuzzy decision tree method.
