Exponentially Weighed Moving Average Control Chart for Gamma Distribution with Type I Censoring

In this article, an exponentially weighted moving average (EWMA) control chart for monitoring the mean level of the gamma lifetimes under the type I censored test is developed based on the conditional expected values. Because the control limits are hard to be found analytically, an algorithm is provided such that the control limits can be determined numerically. The use of the proposed method is illustrated by a numerical example.
