整合FMEA與ABC成本法於衡量設備生命週期成本之研究-以半導體產業實證分析

A study of Integrating FMEA and ABC Analyses in Equipment’s Life-Cycle-Cost Measurement- An Empirical Study of Semiconductor Industry

指導教授 : 陳啟政 鄭文英

摘要


本研究目的是以降低設備購買之生命週期成本為基礎,包含投入資本與保養、使用、維修成本及殘值等組成元素,提供具有成本有效性改善之方法。本研究整合失效模式與效應分析技術及使用作業基礎成本法分析設備維護成本與因設備失效衍生之後續處理作業成本,用以最佳化設備生命週期成本決策,以維持及提升企業競爭力。失效模式與效應分析是一套系統化的分析程序之預防性技術,用以辨識、消除與降低已知或潛在的失效發生、探討其導因及其對系統成效之影響,進而強化系統或產品之可靠度及安全性。作業基礎成本法是將組織所發生的成本,依適當的成本動因,指派至相關的作業上,進而再指派至成本標的上。一FMEA修改表將被用來收集資料並呈現出估計之設備失效成本、效應嚴重度與改善措施成本的對應值,以建立設備失效模式與成本效應分析的主要架構。應用作業基礎成本法將每一事件所引發的作業流程,透過記錄並將活動予以更明確金額化,完整的記錄作業活動所花費之人工、物料、資本及管銷類等成本,提供一完整之設備「生命週期成本」資訊。本研究之主要貢獻為嘗試建構符合業界實務使用之設備生命週期成本評估模式。最後,以某半導體產業個案之設備群來進行分析探討以驗證可行性與實用性並提供業界參考。

This paper explores the improvement pathway to cost effectiveness in semi-conductor industry from the perspective of decreasing equipment life-cycle cost (LCC). To optimize the cost decision regarding equipment life cycle, this paper will adopt two techniques- Failure Mode and Effect Analysis (FMEA) and Activity-based Costing (ABC) - to analyse equipment maintenance expenditure and subsequent cost resulting from equipment failure. The former acts as a preventive approach which could identify and reduce the incidence of failure. Therefore, researchers could gain insights of the causes and effects, and further enhance the reliability andsecurity of system. The latter one is to categorize the costs to related activities and then to the particular cost objects according to different cost drivers. Through Activity-based Costing (ABC), researchers could quantify each activity in detail, such as human resource, materials, capital, and Selling, General and Administrative Expenses (SG and A). In addition, this paper attempts to revise thetable of Failure Mode and Effect Analysis (FMEA) which could demonstrate therelations among expected failure cost, severity occurrence and cost of improvements. This would be a key to failure mode of equipment and cost effectiveness analysis. In conclusion, the paper builds an accurate assessment framework of equipment Life-cycle Cost (LCC). It is believed that it could assist the top management in semi-conductor industry to make better decisions while renewing the firms’ equipment.
