近年來環保議題備受矚目,使得綠能產業受到全球各國的重視。臺灣的綠能產業以太陽能產業最為蓬勃發展,但自2011年起,太陽能產業的獲利因競爭激烈呈現大幅衰退,為此企業必須提高產品的品質及適當的成本管控,方能在競爭激烈的環境中獲得優勢。本研究嘗試建構一適用於太陽能電池製造業,結合品質成本的FMEA推行架構。首先,太陽能電池製造的品質成本項目需被建立並進行逐一的品質成本估算;其次,關鍵製程站將被選定以及進行識別失效模式,矯正措施針對品質成本及RPN值較高的進行。這個包含品質成本概念的FMEA推行架構,可以輔助RPN值的評估,形成第二道防護網,更客觀地確認失效模式改善的先後順序,進而使FMEA的作業更為落實,以達到真正預防失效的效果。本研究建議之品質成本項目及估算公式,企業可依需求自行調整,發展適用自身企業的品質成本估算模式。此結合品質成本的FMEA推行架構,可運用在一般的製造業,透過成本的金額數字量化,使企業更有效預防失效問題並控制成本。 關鍵字:太陽能電池、品質成本、RPN
Green energy industry is regarded as one of a solution to the environmental protection issues facing the world today. In Taiwan, the solar cell sector has been expanding for years and enjoyed high growth due to continuing high demands. Nonetheless, since 2011, the fierce competition and lower demands caused significant shrinkage of revenue in this sector. Thus the solar cell sector needs to improve product quality and exercise better cost control to gain the competitive advantage. This research construct a framework based on FMEA (Failure Mode and Effect Analysis) and Juran’s quality costs method to assist the manufacture of solar cell to be of high quality and improved cost control. The framework is performed as followed: a cross-function team is organized to analyze the quality cost components of solar cell manufacture as well as calculated their quality costs; then the team chooses the key manufacturing station to identify its failure modes and perform the corrective measures for those modes with high RPN value and high quality costs. A case study of a solar cell manufacturer showed that, with the traditional FMEA that catches the potential product failures, the inclusion of quality costs expose the monetary impact of those failure modes and can provide second protective net. The research framework can be applied to other industries should the quality cost components be adjusted and quantified. Keywords: Solar Cell, Quality Cost, Risk Priority Number
