Abstract: According to the difficulty in prevention and control in product manufacturing process because of complexity, variety and different importance of the Quality Characteristics(QCs), the model of immune prevention and control for Key Quality Characteristics (KQCs) oriented to manufacturing process was proposed on basis of biological immune principle with bionics function. KQCs in the manufacturing level and its imperfect factors were firstly defined and the extraction model of KQCs was constructed by means of Artificial Neural Networks (ANN) and Quality Function Deployment (QFD).Then, status eigenvectors of KQCs was presented in the manufacturing level. Furthermore, the functions of KQCs immune recognition, KQCs immunological rejection, KQCs immune memory, KQCs adaptive immunoregulation based on biological immune principle were put forward. Finally, the validity and effectiveness of the theory and model was verified by the application example.
