Abstract :
Measurement error often exists in quality control applications. This error has an adverse effect on the chart’s performance. Measurement error (ME) is a source of variation that may considerably affect the performance of control charts applied within a statistical process control scheme. While the consequences of ME on the actual performance of various control charts has been studied in recent publications, the more important inverse problem of how to specify ME requirements to achieve desirable control chart performance characteristics has not been addressed in the literature. In this paper, we develop guidelines regarding the formulation of power function to distribution-related ME characteristics with known coefficient of variation and investigate the effect of ME and cv on power of mean chart.
