Abstract： In the process of long work hours, operators can produce errors due to mental and physical exhaustion, human reliability is reduced, and it leads to production of incomplete and even endangers humanal safety. In order to understand operator's longest sustainable working time on the premise of given reliability, a method of combining SPCC and ARIMA is put forward. With unit time interval defect rate in the continuous time to measure the reliability of human, and form a defective rate time series. On the one hand, the SPCC is built using DRTS based on ARIMA to determine the sample of UCL, LCL and LWT range. On the other hand, the DRTS of an operator is predicted using ARIMA and SVM with RTA. Finally the prediction curve is put into the SPCC to determine the LWT range. Based on 8 hours, 10 operators DRTS analysis of sampling for every 10 minutes, indicates that the scope of this kind of working parameters for the UCL = [3.89, 4.66], LCL = [4.98, 3.90], LWT = [393450]. Identified a new operator LWT is [435452] minutes, 435 minutes when the operator should stop working to have a rest.
