    • 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 ...

    • Multivariate statistical process control charts based on the approximate sequential ?2 test 

      Kim, J.; Al-Khalifa, K.N.; Jeong, M.K.; Hamouda, A.M.S.; Elsayed, E.A. ( Taylor and Francis Ltd. , 2014 , Article)
      Similar to the univariate CUSUM chart, a multivariate CUSUM (MCUSUM) chart can be designed to detect a particular size of the mean shift optimally based on the scheme of a sequential likelihood ratio test for the noncentrality ...
