| 摘 要： | 首先,基于粗糙集理论提出了农业决策支持系统的实施方案,从而利用粗糙集理论对决策表进行化简,为决策支持系统提供辅助决策所用的规则表。其次,根据决策支持系统的知识获取任务,建立了一种基于粗糙集理论的决策支持系统模型,实现粗糙集理论在农业决策支持系统中的应用。最后,将获取的规则用于农业病虫害的诊断中,利用属性重要度计算方法,对诊断的可信度进行计算。通过对实例运行结果的分析,验证了粗糙集理论与农业决策支持系统相结合方案的可行性。

| Abstract: | An implementing scheme of agricultural decision support system (DSS) based on rough set theory was put forward.Rough set theory was used to reduce the table in order to provide rule table for DSS to make assistant decision-making.According to the task of knowledge acquisition in DSS,a model of DSS based on rough set theory was established.The application of rough set theory in agricultural DSS was achieved.At last,the obtained rules were used in the diagnosis of pests and diseases,and the method of importan... |
