The domain knowledge is organized by knowledge units and knowledge testing is used to establish the evaluation method of the user’s knowledge structure.

The knowledge rules of the process planning are establised on the basis of the knowledge units included in objects such as Parts, Feature, Sequence, Operation and so on.

The necessity and process of transforming text into knowledge is expatiated.

Research on structure design of products based on knowledge units;

To explore the complexity of science & technology system,we should begin from the behaviors of knowledge element,and measure the knowledge of science & technology qualitatively and quantitatively,from microscopic to macroscopic,based on knowledge element.

Collaborative work model in knowledgeable manufacturing cell;

Dynamic task control strategy in knowledgeable manufacturing cell;

Against the deficiency of automata theory being sensitive to system size during modeling manufacturing system,a new method of distributed automata deadlock supervisor was proposed,which was employed to solve the deadlock problem in the knowledgeable manufacturing cell,and the efficiency of automata modeling and operating can be improved effectively.
