The　research　work　presented　in　this　paper　is　based　on　the　concrete　background　of　the　Group　Decision　Support　System(GDSS),　modeling　and　abstracting　the　process　of　the　GDSS.　The　paper　presents　a　design　of　General　GDSS　based　on　multi-agent　approaches.　In　this　design,　we　have　abstracted　a　suit　of　procedures　which　can　hold　the　communication　between　General　GDSS　system＇s　coordinator　(server)　and　GDSS　system＇s　decision-maker　(customer).　It　overcomes　the　limitations　of　traditional　systems,　and　can　be　used　for　the　group　decision　in　many　fields.　This　paper　focuses　on　introducing　the　design　that　many　components　were　giving　by　the　form　of　＂COM＂,　and　the　idea　of　＂agent＂　was　embodied　in　the　design　Of　these　components.　It　offers　some　universal　components　for　GDSS　system　developers,　including:　GDSS　communication　component,　GDSS　site　monitor　agent　component,　cryptogram　agent　component,　preference　agent　component,　alternation　agent　component,　and　cooperation　agent　component,　etc.　A　prototype　has　been　implemented.
