摘要

彈藥為武器發揮戰力之泉源，長期囤儲大量戰備彈藥成為一項必備之任務。為確保彈藥素質及維持彈藥效能，國軍針對變質損壞的彈藥透過整修、保養的方式恢復其堪用妥善；然在統計國內近10年彈藥整修作業爆炸的新聞案件中發現，針對變質或廢棄彈藥執行整修或拆解作業時，潛藏著極高危險性及不確定性。從文獻中探討，IDEF0為流程改善之有效方法，當結合FMEA方法分析潛存失效因子，將可運用於彈藥整修作業之安全性改善。
本研究先以IDEF0建構105公厘高爆榴彈整修作業流程，將其區分開箱、拆解、整修及結合、裝箱等4大流程，並將其拆解繪出細部流程，再依據歷年彈藥勤務通報中，彈藥整修意外事件之肇因，以特性要因法歸納出彈藥整修作業之潛存失效因子計5類15項，利用FMEA分析方法，以問卷方式獲得彈藥從業人員對失效因子之嚴重度、發生率及偵檢度評等，獲得風險優先指數值順序，將數值最高前3項列為優先改善項目，並針對受影響之IDEF0作業流程，以反魚骨圖找出建議改善方案，並修訂IDEF0作業流程；經問卷調查本研究提出之改善方案滿意度達95%，將有利於消除主要失效因子，提升彈藥整修作業之安全性。

Ammunition is the key factor to exert the weapon’s power.This makes it a necessary task to store lots of ammunition for a long period by military. In order to keep its serviceability and effectiveness, military need to maintain and repair the ammunition which had deteriorated in order to recovery their serviceability. From the ammunition explosion accident news over the past 10 years, we find it potentially has high risk and uncertainty to maintain or disassemble the deteriorated ammunition. From the selected literatures, we find IDEF0 is an effective method to implement process reengineering.When it integrating with FMEA method to analysis the potential failure factor, it can improve the Safety of conventional ammunition maintenance operation.
Firstly, this study build the IDEF0 modeling for the maintenance process of 105mm High Explosive Howitzer Cartridge, and divide to 4 main processes which are opening process, disassembling process, repairing and assembling processes, and packing process.Then decompose these main processes into detail procedures.According to the causes of ammunition maintenance accidents from the Ammunition Service Bulletin,this study concludes 5 category and 15 failure factors for ammunition maintenance operation by cause and effect analysis approach.After gathering the severity, occurrence and detectability data of each failure factor from experts by FMEA Questionnaire, this study obtain the sequence of risk priority number and consider the first 3 high score as improvement priorities.Then find the affected IDEF0 modeling processes, provide the suggestion of improvement and revise the IDEF0 modeling.The satisfaction survey for this study is 95%, it shows the approach from this study can exclude the main failure factors and improve the safety of ammunition maintenance operation.
