摘要

製造業的品質管制中，保持良好穩定的產品品質是必備的競爭力，為了監控產品品質，需透過檢測取得相關數據，以判定產品特性是否符合規定；而檢驗量測數值的準確性會受到不同操作者量測誤差影響，故本研究欲找出檢測人員量測差異之原因，以人因工程的方式觀察人員思維並實施辦法改善，期望能將此研究結果運用在相關產業，減少人員量測誤差。

本研究針對實驗室檢測人員於量測過程中的行為活動，經由記錄過程了解檢測者在操作流程中的心智處理與判定方法，探討容易造成檢測人員差異的因素，進而討論出更易辨識及標準化的檢測手法。之後利用量測系統分析中的再現性及再生性 (Gage Repeatability and Reproducibility) 變異的估計值，驗證量測系統改進的幅度。

實驗數據結果呈現此過程顯著降低了人員操作量測的差異，並且定義出的手法可傳承及傳遞給其他部門，促使實驗室的量測系統更加精確。

Keeping stability of operation or product quality is a required competency for quality control in manufacturing industry. For controlling the products quality, the relevant data must be measured and inspected to judge if the quality of products conforms to the specifications. Originally, the accuracy of the measured data varies from each other among different operators. Therefore, in this study the causes of measurement deviations among different operators were analyzed from ergonomics point of view. Improvements were proposed and implemented.

This study started with observing and recording the operations performed by the operators in the laboratory, followed by analyzing the mental process of gage reading judgment during the inspection, and ended with identifying the factors that might affect the operation quality and suggesting the improvement of the measurement method.

It was recommended that a standardized and easier feature identification technique should be helpful. The effects of the new method were verified by using the Gage Repeatability and Reproducibility as an indicator. The results showed that that the data deviations caused by operators were reduced after the new method was implemented. The new measurement method could be disseminated to other departments for improving the measurement quality.
