영문 초록

The coefficient of variation (CV) which represents the ratio of the standard deviation to the mean is widely used to describe the variation of sample data. CV- control chart has the advantage of monitoring mean and variance at the same time at process that process parameter changes from time to time. But, CV- control chart is not sensitive at small shift of coefficient of variation occurs. In this paper, we design of EWMCV control chart to detect small shift of coefficient of variation and evaluates the performance.
