An adaptive step-down procedure for fault variable identification
Kim, Jinho; Jeong, Myong K.; Elsayed, Elsayed A.; Al-Khalifa, K.N.; Hamouda, A.M.S. ( Taylor & Francis , 2015 , Article)In a process with a large number of process variables (high-dimensional process), identifying which variables cause an out-of-control signal is a challenging issue for quality engineers. In this paper, we propose an adaptive ... -
Monitoring multistage processes with autocorrelated observations
Kim, Jinho; Jeong, Myong K.; Elsayed, Elsayed A. ( Taylor and Francis Ltd. , 2017 , Article)In multistage manufacturing processes, autocorrelations within stages over time are prevalent and the classical control charts are often ineffective in monitoring such processes. In this paper, we derive a linear state ... -
Variable Selection-based Multivariate Cumulative Sum Control Chart
Abdella, Galal M.; Al-Khalifa, Khalifa N.; Kim, Sangahn; Jeong, Myong K.; Elsayed, Elsayed A.; Hmouda, Abdel Magid... more authors ... less authors ( John Wiley and Sons Ltd , 2017 , Article)High-dimensional applications pose a significant challenge to the capability of conventional statistical process control techniques in detecting abnormal changes in process parameters. These techniques fail to recognize ...
