本論文研製之主要方向是探討傳統FMEA之RPN方法,將嚴重度、發生度、偵測度相乘所演算出來的RPN值運用於新產品開發,用過去經驗所建立的FMEA表單,作為新產品改善的參考方向。但因傳統FMEA方法並未將產品退貨度列為參考依據,導致客戶退貨不良前幾大往往不是新產品FMEA改善的關鍵項目。 本研究將以傳統FMEA的RPN作為基礎,將標準的FMEA版本做一些微小的演譯,將RPN演算法加入客戶退貨比率(Rejection)於運算式中,作為權重分析因子之一,其目的是希望將客戶的聲音列入FMEA不良分析的考量範圍內,以期降低外部失敗成本,提升產品的競爭能力。
The present paper development the main direction discusses traditional FMEA’s RPN method,The RPN value is calculated by the multiplication of Severity, Occurrence, Detection and comes out to utilize to new product development. Eatablishes the FMEA table list by experience to be the reference direction of new products improvement. But because the traditional FMEA method isn’t treat rejection rate as the reference. So the Top items of return goods always not the critical items be inprovmed in the FMEA table list. This reaserch by traditional FMEA RPN be the base and the standard FMEA edition will do some small develops translates Rejection rate will be a factor and add into RPN’s calculation. Its goal is the hope includes customers’ sound in the consideration scope by FMEA analyzes. The expectation can reduce exterior defeat cost and promote product competitive ability.
