Under　the　background　of　knowledge　economy,　the　research　on　the　problems　of　decision　making　about　scientific　research　organizations　is　not　sufficient,　and　in　order　to　make　beneficial　supplements　to　such　problem,　the　article　realizes　the　scientific　decision　making　of　the　scientific　research　organizations　by　considering　the　knowledge　management　as　mainline,　the　team　decision　making　as　method　and　the　different　team　decision　making　modes　adopted　in　different　stages　through　the　construction　of　modes.　©　2010　IEEE.
