先進型主控制室個人顯示器介面管理作業之探討

Abstract

核能電廠運轉員執行的主要作業為監視與控制，為了在電腦化的主控制室中執行這些作業，運轉員必需執行次要作業，像顯示頁面的導覽與工作站顯示器的配置，這些稱為「介面管理作業」。介面管理在某些情況下會需要過度的心智資源，使得主要作業績效下降，進而影響電廠安全。

本研究以先進型核能電廠中，兩個具有代表性的運轉情節內容作為分析，為正常運轉作業Turbine Startup及異常運轉作業LOCA with LOOP，由熟悉介面團隊及較不熟悉介面團隊兩組運轉人員操作，以了解介面管理在不同情節及不同團隊的差別。研究結果發現：(1)兩組團隊，執行正常運轉作業或異常運轉作業時，導覽在VDU介面管理作業中，所佔的比率都非常的高，表示運轉員會經常的導覽頁面 (2)熟悉介面團隊的介面管理作業次數較多，表示運轉員熟悉介面後，能更熟練的在更種不同的資訊來源中轉換，且收集較多的資訊。(3)按鍵層級模型KLM(keystroke level model)，較不適合用來估計大型複雜系統的介面管理作業執行時間。

The primary tasks performed by nuclear power plant operators are process monitoring and control. To perform these tasks in a computer-based system, operators must perform secondary tasks such as navigating and configuring workstation displays. These are called “interface management tasks.” Demands associated with interface management tasks may be excessive under some circumstances and potentially affect plant safety. In this study, two scenarios performed by experienced team and non-experienced team .we try to find out some difference between operator teams and scenarios. The results of this study are:(1)Both of experienced team and non-experienced team operation in normal or abnormal, use navigating in the interface management works usually.(2)Experienced team can change different interface to get more information proficiency. (3)The KLM(keystroke level model) is not appropriate tool to predict the execution time of interface management tasks in Large Complex System.
