The　collaborative　design　of　a　complicated　mechanical　product　often　involves　conflicting　multidisciplinary　objectives,　thus　one　key　problem　is　conflict　resolution　and　coordination　among　the　different　disciplines.　Since　the　characteristics　such　as　cooperative　competition,　professional　dependence,　compromise,　overall　utility　and　so　on　exist　in　multidisciplinary　collaborative　design　(MCD),　an　effective　way　to　gradually　eliminate　the　conflicts　among　the　multiple　disciplines　and　reach　an　agreement　is　the　negotiation　by　which　a　compromise　solution　that　satisfies　all　parties　is　got.　By　comprehensively　analyzing　the　characteristics　in　MCD　and　considering　the　benefit　equilibrium　among　discipline　individuals　and　team,　a　negotiation　strategy　is　presented,　which　maximize　the　union　satisfaction　degree　of　system　overall　objective　under　the　premise　of　ensuring　the　higher　satisfaction　degree　level　of　each　discipline＇s　local　objective.　A　design　action　of　a　discipline　is　abstractly　expressed　as　a　concession　in　the　negotiation　strategy,　and　a　negotiation　model　used　for　MCD　is　generated　by　establishing　the　relation　between　concession　and　satisfaction　degree.　By　the　relation　between　satisfaction　degree　and　objective　function,　the　mapping　relationship　between　satisfaction　degree　domain　and　physical　domain　is　built　to　get　the　design　solution.　A　negotiation　process　is　planned,　and　a　negotiation　system　framework　is　designed　to　support　the　negotiation　among　multiple　disciplines　and　assist　the　different　disciplines　rapidly　reach　a　consistent　compromise　solution.　A　design　example　of　automotive　friction　clutch　is　given　to　illustrate　the　proposed　method.　(C)　2014　Elsevier　Ltd.　All　rights　reserved.
