Design of Expert System about Database of Text Paper of Engineering Drawing

摘要

In this paper,it is introduced how to design expert system about database of text paper of engineering drawing. Based on the object-oriented programming tool Visual C++6.0 , this paper comments the process of how to apply expert system technology and database technology into the design of expert system about database of text paper of engineering drawing . This expert system makes use of the test paper's difficulty coefficient, random function of expert system, and types of test-paper title, distribution of engineering drawing chapter and section, and level of difficulty to design automatically a piece of reasonable, satisfying test-paper which can be organized and printed immediately through the methods of searching from the database.
