Abstract
Examines trend rules in conjunction with other well‐known
supplementary runs rules to assess their impact when used in control
charting. Focuses on a set of 613 trend rules deemed as potential
candidates to increase the sensitivity of the control chart. The
examined rules are viewed in the light of a stable environment, which
determines the false alarm rate, and then in an environment in which the
process mean is subjected to drift. Results indicate that there are
subsets of trend rules that aid in the detection of out‐of‐control
conditions depending on the severity of the drift and the number of
zonal‐based supplementary runs rules used.
