摘要：
This paper proposed (average)X charts with asymmetric sample size to monitor the asymmetric properties of the process, with an objective function of Tauchi's quality loss during out-of-control period. Numerical results indicate when the magnitudes of upward and downward shift are not large and the difference between them is very large, X charts with asymmetric sample size is more appropriate for dealing with asymmetric quality loss function than that with symmetric sample size. Moreover, the larger loss coefficient rate is, the larger upward shift frequency is, the more efficient the proposed charts are.
