Abstract

Abstract: Control charts based on inspection with gauges are an interesting alternative to monitor quantitative variables when measurement is complex or expensive. The main advantage over variable control charts lies in greater operational simplicity and economy. However, gauge-based control charts are usually less powerful in order to detect shifts in the process than variables control charts, when the same sample size is used. To improve its performance, the use of double sampling on gauge-based monitoring is proposed. The new chart shows better performance than X ¯, S and X ¯ − S charts, for the same average sample size, keeping low sampling cost.
