Abstract

In this paper, we propose an explicit formula of the performance for Exponentially Weighted Moving Average (EWMA) chart by using the Fredholm integral equation of the second kind and the data are described by trend Exponential Autoregressive order p (EAR(p)) model. The performance of the chart is usually measured by the Average Run Length (ARL). The solution is compared with numerical approximations and we found that the computational time of the explicit formula take approximately 1 second while the numerical computations were approximately 10 minutes.
