電腦自動化的監控系統協助運轉人員進行操控，在工業上已有廣泛的應用。高度的自動化雖有其便利及安全性，不過相關監控警報在設計時，多半未能考慮人因方面的因素。本研究的個案為半導體業某公司，廠務廢水處理系統的監控警報改善。嘗試應用人因工程的觀點，找出個案公司的廢水處理系統最常見的監控警報問題，並進行介面檢視及改善。
問題改善前後的廢水處理系統監控警報介面，以人因工程的方法NASA-TLX心智負荷、實驗績效量測等主客觀指標進行驗證，結果顯示改善後的成效良好。受試操作員，皆對改善後的系統滿意度甚高；不僅在值班時處理警報異常，發揮相當程度的助益；同時也降低了操作人員的心智負荷，操作員可集中心力處理真正重要的警報異常事件。此外也顯著改善警報處理效率，符合本研究的目的，並可作為後續半導體業界或其他產業，相關監控警報改善的研究參考。

The automatic monitoring system of the computer assists to operate personnel to control has already had extensive application commercially. Although highlevel automation has its convenient and security. Supervisory alarms relevantly in the design, fail to consider the human factors mostly. The case of this research is one company of semiconductor industry, the supervisory alarms in wastewater treatment system of facility is improved. Try to apply human factors to find out the most common supervisory alarms problem in wastewater treatment system on the case company, looking over and improving interfaces.
Before and after the problems improvement on supervisory alarms in wastewater treatment system, NASA-TLX and experiment performance amount subjective and objective index of examining etc. prove because of method with human factors. The result reveals the effect after improving is good. The tried operators all the satisfaction to system after improving is very high. It is unusual to not merely handle the alarms when on duty, give play to and is analogous to the benefiting of intensity. The mental workload of the tried operators reducing at the same time, deal with the really important unusual incident of alarm in operators very centralized mental and physical efforts. In addition improve the alarm significantly and handle efficiency, the purpose to accord with this research, and can control the improved research of the supervisory alarms to consult relevantly as subsequent semiconductor industry or other industries.
