摘要

由美國格魯曼(Grumman)飛機公司首先提出失效模式與效應分析(Failure Mode and Effects Analysis; FMEA)，應用於飛機操縱系統的失效分析，後來並結合關鍵性分析(Criticality Analysis; CA)而成為失效模式、效應與關鍵性分析(Failure Mode Effects and Criticality Analysis; FMECA)。在新產品開發設計，需要透過不同領域專業人員如軔體工程師、軟體工程師及機構工程師，將設計做整合。強化設計管理績效與品質，將會縮短設計團隊間不必要之作業時程，以期讓產品產出得以在最短期限完成。本研究以失效模式與效應分析FMEA的風險順序數(Risk Priority Number , RPN )為基礎來解決產品開發前10項失效模式所可能產生潛在性的機能問題，讓設計開發團隊在開發階段得以掌握在製程中所會發生不良零件的發生。從FMEA分析後，本研究結合決策實驗室分析法(Decision Making Trial and Evaluation Laboratory, DEMATEL)以反應品質特性的權重，並以更低階模式延伸探討，將FMEA異常問題分類成失效模式、零件種類。再針對各屬性列出其特徵性，最後歸納出較能顯著異常問題之特徵做為探討指標，以做為本研究最後的結果。經由本研究探討，縮短了產品設計時程並事先排除可能潛在失效零件的預防對策，透過問題分析的結果，可做為後續工程變更或製程設備改善及產品移轉之參考依據。

America Grumman air-plane company first bring up Failure Mode and Effects Analysis and applied in operation system failure analysis of airplane. Later, it combined Critically Analysis and become as Failure Mode and Effects Analysis Critically Analysis. At new product design and development stage, it usually needs different professional field workers, such as firmware engineers, software engineers and mechanical engineers to integrate design tasks. Strong design management achievement and quality will reduce many unnecessary processes, saving time and finishng product in a short time. This research will build on the Failure Mode and Effects Analysis Risk Priority Number to solve 10 items potential or possible mechanical problems before new product put into mass production, so that design team will know and have defect components occurred during manufacture process in hand at development stage. After FMEA, this research combined Decision Making Trial and Evaluation Laboratory to represent the weight of quality and extended probe into problem with lower level model to classify FMEA unusual problems to defect phenomenon and component type properties. Then, list all characteristics against each property. Finally, sum up remarkable problem characteristics as probing index and regard it as the result of this research.It reduces design product schedule and exclude potential or probable defect components prevent ways in advance. After analyzing the problem, the result can provide a basis for engineering change or process equipment and product transfer.
