建立了面向行政首长和农业主管部门的地、县级农业生态系统智能决策支持系统(IDSSA)。系统实现“四库一体化”结构,提出全新的方法库概念和适合于大体量知识库的产生式规则法、框架法、关系数据库法结合的知识表达体系。采取回旋阶梯式和缩进式结合的方法,通过推理、人机交互,较好地解决了农业决策的半结构化和非结构化问题。系统驱动为知识—数据的共轭驱动和用户驱动结合的模式。
A prefectural and county-level agro-ecosystem intelligent decision support system (IDSSA) for executive heads and agricultural authorities has been established. The system realizes “four-storey integration” structure, proposes a new concept of method storehouse and puts forward a knowledge expression system which combines generative rule method, framework method and relational database method suitable for mass knowledge base. Adopting the combination of convolution ladder and indentation, the problems of semi-structure and unstructured agriculture decision-making are solved well by reasoning and human-computer interaction. System-driven knowledge-data conjugate drive and user-driven mode.
