摘要：Group Decision Support System(GDSS) is an import content in CSCW domain. In modern time, you have to face more and more complicated condition to make a decision, so the importance of GDSS has become more and more outstanding. At present the traditional data warehouse(DW) can not support GDSS authentically, so we introduce a model of DW to support GDSS, and the shortened form is SEGDDWS. SEGDDWS will enhance the level of enterprises's decision support, but the existing algorithms can not be applied to SEGDDWS directly. This paper puts forward a new active data refresh algorithm which based on SEGDDWS we have introduced. This algorithm can refresh the decision information effectively, and we prove the feasibility by validation. © 2003 IEEE.
