| Abstract: | Expert system is an important applied field of artificial intelligence, the production system based on backward reasoning is the most effective expression mode of knowledge and the basic model of logical reasoning. This paper analyses its basic structure in detail, describes non-certain knowledge with rules and certainty factor, puts forward the algorithm of backward and non-exact reasoning, gives the programming methods of explanation mechanism and knowledge acquisition mechanism, which provides an important basis for the designing of expert systems. |
