To cope with the problems of monitoring dynamic and variable quality variation for individualized customization, diagnosing the abnormal variation and adjusting the process at the right moment, is a difficult problem that individualized customization faces in process quality control. This mode dealt mainly with constructing and running dynamic quality control system, integrated several enabling technologies such as process quality analysis on-line based on similarity process, process quality diagnosis based on Elman and expert system of process quality adjustment. It is basis of realizing network, intelligent and automatic process quality control.
