针对决策树推理的专家系统局限于线性推理的问题,提出具有非线性推理功能的玉米缺素诊断专家系统。该系统采用有向无环图实现推理,可以从事实和结论两个方向进行正向及逆向推理,解决了玉米缺素诊断困难的问题,具有专家级的诊治水平,可以给出相应的解决方案和示例图片展示。实践证明,该系统预测结果直观,且具有实用性强、操作简单、界面友好等特点。
For the serious constraint in linear inference decision tree expert system, the paper proposes a nonlinear inference corn deficiency diagnosis expert system. The system can realize the two directions inference on facts and conclusions, from both forward and backward, by using an oriental and acyelic graph method. It has expert level in solved corn deficiency problem, and gives appropriate cases and pictures. Practices have proved that it predicts intuitive results, with high practicability, simple operation, and friendly interface and so on.
