　　本研究以風險管理的分析手法–作業風險管理(Operational Risk Management Management，ORM)與失效模式與效應分析(Failure Mode and Effect Analysis, FMEA)以及發明式的問題解決理論 (Teoriya Resheniya Izobreatatelskikh Zadatch，TRIZ)作為本研究之方法，應用於引擎之機匣外徑製程之可能改善評估。步驟一以作業風險管理(ORM)的危險識別來探討其機械加工可能潛在的失效模式;步驟二風險評估則使用失效模式與效應(FMEA)針對關鍵潛在的失效原因來識別加工失效的風險大小;步驟三風險控制方法分析部份則導入TRIZ，藉由TRIZ的屬性轉換與矛盾矩陣的發明原則，尋找出解決良率改善的可能方法，提升產品製程良率。相較於以往作業風險管理的解決方案大多集中於人為失誤，並不能針對工作方法提出創新解決，至於使用TRIZ理論，能使工作方法有更多探討與意見，讓企業的競爭力提升。

關鍵字：作業風險管理(ORM)、失效模式與效應分析(FMEA)、發明式的問題解決理論(TRIZ)。

ABSTRACT

　To improve the maching quality of an aero engine casting, this study uses ORM (Operational Risk Management) to identify the possible failure risks during the manufacturing process, We also apply the principle of FMEA(Failure Mode and Effect Analysis) to estimate the magnitudes of all risks . Finally, the use of TRIZ (Teoriya Resheniya Izobreatatelskikh Zadatch) provides practical to increase the productivity.

Keywords: Operational Risk Management (ORM); Failure Mode and Effect Analysis (FMEA); Teoriya Resheniya Izobreatatelskikh Zadatch(TRIZ)
