Abstract: An efficiency analysis is conducted and an optimal design method is proposed. Average product length (APL) is introduced as an efficiency evaluation criterion. A Markov chain approach for the calculation of APL of adaptive control chart is presented. Then, the application range is provided by comparing detection efficiency of adaptive control charts and standard Shewhart chart. At last, an optimal design procedure of adaptive control chart for different size of process mean shift is proposed.

Key words: adaptive control chart, average product length(APL), Markov chain
