基于产生式与框架知识表示的造林专家系统研建

本文根据造林专家确定造林地立地条件和造林模式的知识构成,采用了产生式表示法与基于框架表示法相结合来表示.设计了相应的规则库和事实库结构,优化了推理规则的表示方法,将多条规则表示的造林推理知识简化为一条规则,给出了实例,在此基础上详细地给出了具体的推理算法.设计了系统的功能结构,实现了一个造林专家系统,在实际生产中进行了应用.

Forestation expert system based on the production and framework knowledge representation

In this paper,according to the knowledge constitution of forestation experts determing the plantation site conditions and forestation model,the method combing production representation and framework-based representation was adopted.This paper designed the structure of corresponding rule base and the fact base,optimized the inference rules express ways to express many of the forestation rules knowledge reasoning with a simple rule,gave examples and the specific reasoning algorithm.The system functional struc...
