支持企业群体决策的一种数据仓库模型

群体决策支持系统是计算机支持的协同工作的重要组成部分,数据仓库提供了对OLAP和决策支持系统的支持.但现今的以数据仓库为基础的决策支持系统大都不能很好地支持决策者之间的协同决策.为更好地支持企业群体决策,给出了一种支持企业群体决策数据仓库的模型(SEGDDWM).该模型以分析企业的不同生产活动为目标,既可以为决策者们的协同决策提供辅助帮助,又可以为决策者们提供面向某个主题的决策服务.由于该模型引入了组合维的概念,不仅大大加快了决策信息查询的速度,而且扩展了单一数据仓库的能力,为决策者们提供统一的协同决策支持平台,也给出了一个零售企业的群组决策过程.

A Multi-Data Warehouse Model for Supporting Enterprise Group Decision

Group Decision Support System is an important part of CSCW .Data Warehouse (DW) provides the supporting for OLAP and DSS .But most present DSS based on DW don't support well the cooperative decision among decision-makers .To give the Enterprise Group Decision a better support ,we put forward a Data Warehouse model (SEGDDWM) for supporting enterprise group decision. This model aims at the analysis of different productive activities of enterprises, which can not only provide assistance for cooperative decision among decision-makers, but also support decision service about some subject. Because the model imports the idea of Assemble Dimension, it not only fastens greatly the querying speed of decision information, but also expands the ability of single DW. As a result, it provides united cooperative decision supporting platform for decision service According to this model , we also provide a Group Decision(GD) process of a retail enterprise.
