In this paper, the quality control technique and the optimization of adjustment interval of one dimensional quality characteristic are extended to multi-dimensional case in which the vector of the quality characteristics or important financial indices of firms shifts with time. A special multivariate triangle control chart is proposed to control such kind of process. An application is illustrated to monitor and predict the soundness of insurers of U.S. Finally, 7 important issues for further study in future are presented.
