失效模式與效應分析(failure mode and effectsanalysis, FMEA)乃是一種預防性的風險管理技術，主要應用於分析與辨認產品設計系統的潛在失效模式，是一種發掘設計與製造流程風險的有效方法。本研究以失效模式與效應分析法探討電腦組裝流程的潛在失效模式，並提出對應之改善措施以降低電腦發生的故障風險。在研究中首先分析電腦組裝的流程，並探討各個流程可能發生的失效(故障)與原因，分析結果發現在電腦組裝過程中存在17 個潛在失效問題；而利用FMEA分析各個失效模式與效應，並得到其風險優先數。最後本研究提出降低失效風險的改善對策與建議，電腦組裝工程師可依據風險優先數與相關的對策，有計畫地採取適當的措施來降低組裝流程的失效風險，進而達到提高電腦可靠度的目的。

Failure mode and effects analysis (FMEA) is a preventive technology of risk management that is applied to analyze and to identify the potential failure modes in a system. And appropriate improvement actions can be
taken for decreasing the error. The purpose of this study is to apply failure mode and effects analysis to decrease the failure risks of computer assembly. In order to analysis the failure modes, the assembly process of computer is identified and 17 failure problems exist in the process. FMEA is used to analysis the effects of failure modes and
to determine the risk priority numbers. Moreover, the improvements of each failure problem are suggested. The engineers could accord to the risk priority numbers and the related suggestions to decrease the failure risks while assembling computers.
