Abstract :
The effect of adjustment and monitoring method was discussed for autocorrelation based on the process AR(2). In the method, the autocorrelation is removed by introducing the MMSE adjustment method. The model of the process mean drift is analysis in the adjustment. The influence of S/N, ARL and alarm probability is studied for process mean drift in the control chart. The phenomena are found that the drift can be detected in the start or it is difficult to be detected in other time. The phenomena depend on the autocorrelation and process mean drift mode. The drift mode of process mean is crucial for the phenomena.
