Abstract :
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´ 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.
