The　negotiation　characters　in　the　multidisciplinary　collaborative　design　are　analyzed,　and　a　negotiation　strategy　that　make　the　union　satisfaction　of　the　overall　goal　maximum　on　the　premise　of　guaranteeing　the　satisfaction　level　of　every　discipline＇s　local　goal　is　put　forward.　The　game　theory　is　utilized　to　make　a　formal　description　to　the　negotiation　strategy,　and　a　negotiation　model　used　for　multidisciplinary　collaborative　design　is　generated.　On　this　base,　a　negotiation　management　system　is　developed　for　supporting　the　negotiation　process　among　the　disciplines.　Through　synthetically　considering　and　weighting　the　suggestions　of　each　side,　a　recommend　scheme　is　given　by　the　negotiation　management　system,　which　can　help　the　different　discipline　designers　rapidly　reach　a　consistent　design　solution　of　product,　and　an　example　is　given　to　illuminate　and　validate　the　model　and　the　method　put　forward.
