摘要：

In this paper, we propose an auxiliary-information-based (AIB) double EWMA-t (AIB-DEWMA-t) chart for monitoring the process mean. The DEWMA-t chart encompasses the EWMA-t and AIB-EWMA-t charts. The Monte Carlo simulations are used to compute the run length characteristics of the AIB-DEWMA-t chart. Based on detailed run length comparisons, it is found that the AIB-DEWMA-t chart may uniformly and substantially outperform the AIB-EWMA-t chart when detecting different shifts in the process mean. In addition, the AIB-DEWMA-t chart is uniformly more sensitive than the DEWMA-t chart. Similar trends are observed when comparing these control charts with the variable sampling interval feature. A real dataset is also considered to demonstrate the implementation of the proposed chart.
