摘要
The target of statistical process control is to identify changes in the behavior of controlled process as quickly as possible. Therefore, as a quality measure of control charts, we use characteristics which quantify the delay between the occurrence of change and its identification by the control chart. The average run length is a commonly used characteristic which does not reflect a real situation. A new characteristic is suggested which is computed in the case of progressive wearing out of the system. We assume several types of progression. The Markov chain approach is used for computation of average delay.
