Control charts for process average and variability based on linguistic data

Wang and Raz presented a generic approach for constructing attributes control charts using linguistic data to control the process average. In this paper, we propose new linguistic control charts for process average and process variability based on the estimation of probability distribution existing behind the linguistic data.
