白绒山羊疾病诊断专家系统推理机的设计

Design on Inference Engine of White Cashmere Goats Disease Diagnosis Expert System

多数动物疾病诊断专家系统采用单一的推理机制,容易造成诊断不准确的问题。根据白绒山羊疾病诊断的特点,引入基于事例推理和基于规则推理的混合推理机制,使用面向对象的程序设计方法,设计白绒山羊疾病诊断专家系统推理机的原型系统。测试表明,该推理机较好地反映了人类专家的推理过程,诊断结果准确,具有很高的实用价值。

Most animal disease diagnosis expert system adopted single reasoning mechanism,and it easily leads to inaccurate diagnosis. According to the characters of cashmere goats disease diagnosis, combined with the rule- based reasoning and the case- based reasoning, the hybrid inference engine is produced, adopting the method of object oriented programming, designing the prototype system of inference engine of cashmere goats disease diagnosis expert system. The result shows that the inference engine reflect better the reasoning process of human experts, the diagnosis result is accurate, has the very high practical value.
