科技產業在經濟全球化下,為追求國際競爭力,從業人員採用輪班方式維持生產線日夜的持續運作,生產上除了提升產能與製程良率外,人員與設備的安全更是不容忽視,對突發事故的應變處理能力也是維持生產運作的關鍵因素。本研究旨在探討輪班、警報呈現方式及警報數量對監控人員操作績效與心智負荷的影響。本研究以氣體監控系統的異常處理進行模擬,採用4×2×4的實驗設計,實驗因子有輪班班別採日轉夜班第2日、日轉夜班第14日、夜轉日班第2日、夜轉日班第14日四種水準,警報呈現方式採單筆式與清單式二種水準,警報數量採3、5、7、9四種水準。參與者必須在時間內判斷異常狀況並完成介面操作點選與數學計算兩項作業,在實驗中,操作績效以主、次要作業錯誤次數,心智負荷以NASA-TLX量表來衡量。研究結果顯示四班二輪之人員由夜班轉換日班因日夜節律的改變,參與者因生理時鐘需做反向的調整故警報處理介面操作錯誤次數較高,人員主觀偏好上也有較高的心智負荷。在操作介面上警報呈現方式則以單筆式呈現方式較不易干擾操作人員注意力,故參與者有較佳的績效。警報數量在介面設計上建議維持在7個以下人員有較佳的操作績效。
With the economic globalization, employees are asked to take shifts keeping continuous operation in production to possess the international competitiveness of technical industry. It’s not only important to improve production capacity and process yield, but also important to keep the safety and health of employees. The research investigated the shift, display type and the number of alarms effect of monitoring staff performance and mental workload. In this study, simulation of gas monitoring system and adopts 4×2×4 independent variables combination, and then There are four level shift factors include four alarm levels of two display type. Participants must complete the primary and secondary operation at the same time. The dependent variables include the error rate of primary and secondary operation and NASA-TLX mental load scale. Results show that the four-shift-two-round employees when switching from night shifts to day shifts have a higher mental workload and a higher operation error rate. In addition, the display type shows that the single type of alarm display is less likely to distract participants, which leads to a better performance. The number of alarm should be designed to be less than 7 will have a better performance
