Modified chart with optimized ARLs in autocorrelated processes

Prajapati, D. R.; Singh, Sukhraj - In: The TQM Journal 27 (2015) 5, pp. 633-647

Purpose – The purpose of this paper is to counter autocorrelation by designing the chart, using warning limits. Various optimal schemes of modified chart are proposed for various sample sizes ( n ) at levels of correlation (Φ) of 0.00, 0.475 and 0.95. These optimal schemes of modified chart...
