气流干燥专家系统推理机的设计与实现

Design and Implementation of an Inference Engine of the Pneumatic Drying Expert System

重点研究了气流干燥专家系统中推理机的实现技术,推理算法。利用关系数据库SQL Server 2000设计干燥专家知识库,构造了一个气流干燥专家系统。其推理机能够有效模拟现场操作人员的思维,在生产过程中可作为判断干燥后精矿水分是否符合要求的辅助工具。该推理机采用了演绎推理、确定性推理和前向推理相结合的推理策略,提高了推理机的效率,获得了较好的推理效果。

Implementation techniques of inference engine,inference algorithm are mainly studied,and the drying knowledge based on SQL Server 2000 is designed,meanwhile it build up a pneumatic drying expert system,whose inference engine can simulate the operator＇s thought efficiently.As a assistant tool,this system could judge the concentrates＇ humidity. The inference engine adopts a tactical thinking based on deductive inference,definite reasoning and forward reasoning,they improve the efficiency of reasoning,and preferably achieve the effect of reasoning.
