초록

DD-plot은 분류문제를 풀기 위한 유용한 비모수적 방법이다. 우리는 이러한 DD-plot을 다변량공정에서 이상상태를 탐지하기 위한 그래픽 방법으로 사용할 수 있다. 본 논문을 통하여 이상상태를 탐지하기 위한 그래픽 방법으로서 동적 DD-plot과 동적 품질지수그림을 제시하고자 한다.

It is well known that the DD-plot is a useful graphical tool for non-parametric classification. In this paper, we propose another use of DD-plot for detecting the out-of-control state in multivariate process. We suggested a dynamic version of DD-plot and its accompanying a quality index plot in such case.
