영문 초록

The coefficient of variation represents the ratio of the standard deviation to the mean, and it is a useful statistic for comparing the degree of variation from one data series to another, even if the means are drastically different from each other. Recently, CV control chart is studied steadily by control chart to control mean and variance of process at the same time. However, CV control chart has low performance in detecting small shift. In this paper, we propose CV-CUSUM control chart using CUSUM scheme which is sensitive in small shift.
