面向对象技术在玉米产量预测专家系统开发中的应用研究

A study of using object-oriented technique in developing yield forecasting expert system of corn

把面向对象的技术应用与专家系统的知识库和推理机的建造中,在此基础上提出了一种基于规则推理网络模型的优化搜索的设计思路,把该方法应用于吉林省农作物熟区动态区划专家系统中的玉米参量预测子系统的开发中,取得了很好大效果。在实例应用中采用定性与定量相结合的综合多级推理,降低了问题求解的难度,更贴近人类专家的思维过程。

Using Object -Oriented technique in building Knowledge Base and Rule Reasoning Model of Expert System,we bring out a new method based on rule reasoning network model which search path is better.Use this means in″Yield Forecasting Expert System of Corn of Jilin Province″and getting very good effect,in the application we use integrating multilevel reasoning which combined qualitative and quantitative reasoning,it degrade the difficulty and more closeing to the thinking process of human domain expert.
