Modeling method of multivariate statistical control chart for small-batch manufacturing process quality

Based on the study of multivariate statistical process quality control chart and small-batch manufacturing process, a kind of synthetical modeling method was put forward to deal with multivariate statistical process for small-batch manufacturing. Practical application and emulational instance show that this modeling method can make the best use of the obtained data, build control model dynamically, consequently resolve the problem of lacking modeling data in small-batch manufacturing process.
