The process knowledge,which is universal,has close connection to the students mathematical capacity and initiative.

The process knowledge, which was universal, had compact connection with the students’mathematical capacity and initiative.

Using process knowledge of the status model expressed in the form of ontology,process performance influence relation graph is generated to express performance influence relation among elements of activities in a process.

A methodology for on-line process identification is developed for use the chemical process industry.

Derives a PID parameter auto-tuning algorithm based on process identification from anormal PID controller.

To adapt to the needs of application of advanced control, process identification combined with the design of controller design technology.

Research on the Knowledge Process of M Power Design Enterprise;

According to the analysis of knowledge characteristics,the knowledge use and management were achieved by constructing knowledge tool,maintaining data carrier and conducting control on knowledge process.

On the basis of analyzing the business process and the knowledge flow of new product research & development teams,the knowledge process is divided into four phases as knowledge obtaining,knowledge combining,knowledge using and knowledge sharing,a knowledge process model is built up,and the main knowledge activities in every phase are also analyzed.
