近年來中國大陸鋼廠產能過剩，導致國際鋼鐵市場供需失衡，鋼鐵業經營環境更加險峻，為突破上述經營困境，企業除了進行新產品開發與新技術的導入，提升產品品質與設備可靠度、降低企業成本亦為企業重要課題。
地球氣候異常造成極端天氣現象，如降雨模式改變、水災、乾旱和風災等。極端天氣現象頻率增加水資源供給調配不易。鋼鐵冶煉過程中設備幾乎都處於高溫狀態，非常需要透過水重複循環達到冷卻效果；設備依靠電力才能順利運轉，但目前外部供電環境不穩，這兩個因子對鋼廠是缺一不可，都會造成整個鋼廠生產停擺且重啟製程不易，穩定供應水資源與電力也是重要因素。
綜合上述兩項說明選擇動力工場發電機組作為分析對象，藉由失效模式與效應分析(FMEA)來評估製程設備的風險，列出製程設備中所有的失效模式，挑選RPN數值前五高失效模式利用故障樹分析(FTA)確實找出故障根因，並用萃思方法(TRIZ)找出改善對策加以改善，此套方法經過驗證可降低失效模式RPN數值約64%，設備維修或備品更換頻率可降低約50%，改善年效益約65萬元，讓企業往後遇到設備問題時，可使用此方法作為決策的參考依據。

In recent years, overcapacity in China's mainland steel mills has led to an imbalance between supply and demand in the international steel market. The operating environment of the steel industry is more dangerous. In order to break through the above-mentioned operational difficulties, companies will not only introduce new product development and new technologies, but also improve product quality and equipment reliability. Corporate costs are also an important issue for companies.
Abnormal Earth weather causes extreme weather phenomena such as changes in rainfall patterns, floods, droughts and typhoons. The frequency of extreme weather phenomena increases the supply of water resources is not easy. In the iron and steel smelting process, the equipment is almost in a high temperature state, and it is very necessary to repeat the circulation through the water to achieve the cooling effect; the equipment relies on electric power to operate smoothly, but the external power supply environment is unstable at present, these two factors are indispensable for the steel mill, which will cause The entire steel mill production is shut down and the restart process is not easy. The stable supply of water resources and electricity is also an important factor.
Combining the above two instructions to select the power plant generator set as the analysis object, the failure mode and effect analysis (FMEA) is used to evaluate the risk of the process equipment, list all the failure modes in the process equipment, and select the top five high failure mode of the RPN value. Fault Tree Analysis (FTA) does identify the root cause of the fault and uses the TRIZ method to identify improvement measures to improve it. This method has been verified to reduce the failure mode RPN value by approximately 64%, and equipment maintenance or spare parts replacement frequency can be reduced. About 50%, improve the annual benefit of about 650,000 NT dollars, so that enterprises can use this method as a reference for decision-making when they encounter equipment problems in the future.
