Design of inference engine for geographic expert system

This paper presents design approaches and principles of inference engine for Geographic Expert System (GES), and probes basic control strategies of inference engine and the algorithms of program realization as well as search strategies of reasoning knowledge. In addition, the paper discusses a thorough plausible reasoning problems in GES, and analyses basic idea of Bayes algorithms for plausible reasoning as well as structure principles and approaches of reasoning rules. On the basic of theories mentioned above, the author designs the inference engine of Water and Soil Conservation Expert System (WSCES). And taking the structuer of inference engine as an example, the author expounds the organization principles of reasoning network and design methods of reasoning rules as well as reasoning algorithms, and elaborate organization structures of reasoning knowledge.
