The Economic Design of $\bar{x}$ -S Chart Considering Measurement Error
측정오차를 고려한 $\bar{x}$ -S 관리도의 경제적 설계
Abstract
For statistical process control, the process data are collected by the measurement system. But, the measurement system may have instrument error or/and operator error. In the measured values of products, the total observed variance consists of process variance and variance due to error of measurement system. In this paper, we design more practical T-s control chart considering estimated measurement error The effects of measurement error on the expected total cost and design parameters are investigated.
