Univariate and multivariate control charts for monitoring dynamic-behavior processes: A case study

Haridy, Salah; Wu, Zhang - In: Journal of Industrial Engineering and Management (JIEM) 2 (2009) 3, pp. 464-498

The majority of classic SPC methodologies assume a steady-state (i.e., static) process behavior (i.e., the process mean and variance are constant) without the influence of the dynamic behavior (i.e., an intended or unintended shift in the process mean or variance). Traditional SPC has been...
