摘要

過去核能電廠的嚴重災變事故皆與核能電廠運轉人員的疏忽、錯誤操作和錯誤
決策有關。因此核能電廠運轉人員面對緊急事件的處理能力和運轉員在面臨緊急、
異常程序情況時其心智負荷狀況高低程度，對核能發電廠的運轉安全有重要影響
性，而現有主要心智負荷衡量方法中，績效衡量、生理參數衡量、主觀評比衡量，
皆為事後或於任務進行中衡量人員心智負荷情形，缺乏了一種能夠事先推測人員心
智負荷的衡量方法，本研究以McCracken-Aldrich 衡量技術之VACP 衡量表，以此
方法針對任務來事先評估人員於執行任務時所需的注意力資源需求情形，並以NASATLX
衡量問卷方式，得知核能電廠主控室運轉人員於執行任務時其心智負荷情形，最
後對此兩方法所獲得的資料進行分析，最後得到其相關性和回歸模型，說明任務注
意力資源耗用高低情形是可以用來解釋並預測運轉員對於該任務之心智負荷高低
的，望能作為之後核能電廠任務作業程序參考，以期能夠應用於評估與預測目前核
電廠運轉的效能與安全，更可以對未來核能電廠建造或更新計畫有所助益。

In the past, serious accidents of nuclear power plant usually had relation with the negligence, error handling and wrong decisions of operators. Therefore, to understand and be able to measure mental workload levels of operators are significant for safety issues in the nuclear power plant, especially when operators face emergency conditions. However, most of the existing major methods of mental workload measurement, which can be categorized into task performance measures, physiological parameters measures and subjective rating measures, are post analysis, or the mental workload can only be measured during performing tasks. Therefore, these methods are lack of a way to predict mental workload. Hence, by applied an abnormal operation procedure as a case, this study used the McCracken-Aldrich technique to analyze and predict mental workloads on sequential tasks of the procedure. Then, the NASA-TLX questionnaire was used to collect operators' subjective rating of their mental workloads on these tasks. Finally, the study analyzed the information obtained by the two methods, and obtained their correlation and constructed a regression model. Results showed that the level of resource consumption task attention used in the McCracken-Aldrich technique can effectively explain and predict the mental workloads of operators. The findings should be able to help the improvement on the nuclear power plants task procedure.
