摘要
针对鱼病知识的特点,给出了有关鱼病、症状与病因相互关系3个定义;利用定义,采用逻辑型产生式规则建立了主要鱼病的知识库;在总结和归纳专家诊断鱼病经验的基础上,建立了鱼病诊断推理框架,并给出了推理中的核心算法。实践表明,采用逻辑型产生式规则减少了规则的数量,提高了鱼病诊断专家系统推理的速度和准确性。
To the characteristic of fish disease knowledge,the knowledge database of fish disease is structured based on logic production rules,which had structured by three definitions about the mutual relations disease,symptom and pathogeny having given.Based on summarizing and concluding experience experts diagnose fish diseases,the reasoning frame of fish disease diagnose and the core arithmetic of reasoning had structured.It proves that application of logic production rule can decrease the amount of rules and promote the reasoning speed and veracity of Fish Disease Diag-nose Expert System(FDDES).
