摘  要:
粗糙集是一种用途广泛的软计算方法,继概率论、模糊集、证据理论之后的又一个分析和处理不确定性、不完备信息的有效工具。为此,基于粗糙集理论的Pawlak模型,以葡萄3种病害(真菌类病害、细菌类病害、病毒类病害)为例建立知识库,对知识库进行知识约简,从而得出诊断规则,建立葡萄病害诊断模型进行诊断,从而达到预防和提高产量的目的。

摘  要:
Rough set,a versatile soft computing method,is another effective tool to analyze and deal with uncertainty and incomplete information after the birth of probability,fuzzy sets,and evidence theory.As to the fact that present gradual increase of grape diseases curbs output and economic efficiency,this paper is an attempt based on Pawlak rough set model to first set up knowledge base by studying three kinds of grape diseases(fungal,bacteria and virus).And then the knowledge base will be tested against knowledge reduction for generating diagnostic rules.We can diagnose various grape diseases by establishing a grape disease diagnostic model for the purpose of disease prevention and output increase.
