摘要：

A new control chart, called the theta chart, for monitoring the mean of a process with bivariate quality characteristics is proposed. It can identify a rotation, shift or alternation between the subgroups of the process mean. The conventional application of chi(2) chart to identify a sudden shiA of the process mean is also expanded to identify a change of the process mean or a change of the process dispersion. Furthermore, when used together, the theta and chi(2) charts could provide further insight into the process.
