摘要
综合运用了J2EE、数据仓库、联机分析处理、数据挖掘等技术,建立了一个多层次分布式电力营销决策支持系统。该文阐述了该决策支持系统的体系结构,分析了从操作型数据库到数据仓库和数据集市的数据采集模式,实现了Winters模型、一元线性回归以及二元指数平滑等预测模型的设计,从而为电力营销活动提供了重要的决策支持。
The J2EE,data warehouse,Online Analytical Processing(OLAP) and data mining technologies are used to build a multi-tier distributed electric power marketing Decision Support System(DSS) based on J2EE.A new architecture for the DSS is proposed to describe the new application model.A method is presented to collect data from traditional operational database and to store the data to data warehouse and data mart.And Winters model,simple linear regression model,quadric exponential smoothing model are realized to provide electric power marketing officers with efficient decision support.
