| Abstract: |
| With network technology,a safety evaluation expert system for HVDC transmission system is designed,which manages the data and information for safety evaluation to realize effective data storage,exchange and query.Its business flow and structure are introduced with the construction of knowledge library:rule-base and fact-base.The rule representing method applies production mode and its data structures are described.Practices show that the efficiency,availability and precision of the knowledge library based safety evaluation expert system have been improved. |
| Key words: safety evaluation,knowledge library,production mode,rule representing method |
