摘要
SDSS是较为先进的决策支持系统,但由于其模型库中的模型固定不变,因此在实际应用中具有一定的局限性。提出了集成数据仓库DW、知识仓库KW和模型仓库MW作为底部架构的体系结构,能有效解决这一问题。该架构简化了模型获得和编码任务,增强了决策的有效性和智能性,提高了决策效率。
Spatial Decision Support System (SDSS) is an advanced Decision-Support System (DSS) at present. But the models in the model database are unchangeable, so it is certainly limited in practice. The structure of the system based on data warehouse, knowledge warehouse and model warehouse was put forward, which can effectively solve the problem. The structure simplifies the model obtainment and the coding task, and strengthens the effectuation and intelligence of decision so as to improve the efficiency of decision making.
