| 摘 要： | 探讨了农业生产信息决策支持系统中的知识表达系统,并利用粗集理论中的决策逻辑找到了一种对决策表表达知识化简的算法,形成了从粗集理论到决策知识的实际化简。最后以实例分析知识的简化过程,通过数据分析、推理,得到关键的决策方案。

| Abstract: | This paper discusses about Knowledge Representation Systems (KRS) in Agriculture Decision Support System (DSS), constructs the arithmetic based on the knowledge representation reduction of the decision tables, and forms the reduction of decision representation from Rough Set. Finally, an example is given to analyze the process of knowledge reduction and a decision scheme is produced based on data analysis and deduction. |
