Abstract :
For the 2-order auto-regressive process with unknown parameters, further analysis of the effect of the estimation of parameters to the performance of control charts are provided. The influence of the process parameter to the performance of control charts is obvious and the time series process needs to be estimated, so the impact of parameters´ valuation is necessary to be analyzed. Some conclusions and the transformation of the performance of control charts which arises from parameters´ valuation are summarized by numerical results.
