摘要:
This article studies a unique feature of the binomial CUSUM chart in which the difference (d(t) - d(0)) is replaced by (d(t) - d(0))(2) in the formulation of the cumulative sum C-t (where d(t) and d(0) are the actual and in-control numbers of nonconforming units, respectively, in one sample). The results of the performance studies reveal that this new feature is able to increase the detection effectiveness when fraction nonconforming p becomes three to four times large as the in-control value p(0).
