An $\overline{X}$ -Control Chart Based on the Gini′s Mean Difference
지니(Gini)의 평균차이에 기초한 $\overline{X}$ -관리도
Abstract
Estimation of the process deviation is an important problem in statistical process control, especially in the control chart, process capability analysis or measurement system analysis. In this paper we suggest the use of the Gini's mean difference for the estimation of the process deviation when we design the control limits in construction of the control charts. The efficiency of the Gini's mean difference was well explained in Nam, Lee and Jung(2000). In this paper we propose an
