摘要: 牛病发生频繁和牛病专家相对不足给牛病的及时诊断与防治带来很大困难。因此,本文在对牛病的特点和牛病诊断思维模式进行分析的基础上,根据牛病诊断与防治的特点和要求,将数值诊断和案例推理技术引入到牛病诊断与防治系统中,结果表明应用两种诊断推理结合的方法正确率高于以任意一种方法诊断的正确率。建立了数值诊断与案例推理相结合诊断的牛病诊断推理模型,并且基于此模型开发了牛病专家诊断系统。

Abstract: It is very difficult to make timely diagnosis and treatment for cattle disease because of the frequent cattle disease and the lack of cattle disease experts. In this paper the case-based reasoning diagnosis was adopted, according to the characteristics of the cattle disease diagnosis and treatment. And the model of numerical and case-based reasoning diagnosis was developed that based on the analysis of the characteristics and the diagnosis mode of cattle disease. It is proved that bined method has higher accuracy than any single kind of the method. And then, the diagnosis expert system for cattle disease was also implemented.
Key words: case-based reasoning; numerical diagnosis, cattle disease, diagnosis expert system
1 引言
随着我国养牛业的迅速发展,养殖规模的不断扩大,牛病的预防和治疗也变的十分重要。但是由于在饲养者管理不善,养殖环境较差等诸多因素的影响,使得牛病发生频繁,并且从事牛病诊断的专家数量很难满足牛病诊断的需求,牛病给畜牧养殖用户带来的经济损失也越来越大[4]。
