For　intuitionistic　fuzzy　multi-attribute　decision-making　problems　where　the　preference　is　conflictive　and　the　weight　information　is　unknown,　a　decision　making　method　is　proposed　based　on　multi-objective　decision　making.　Firstly,　the　multi-objective　decision　model　of　decision　differences　degree　and　preference　conflict　degree　being　chosen　as　the　goal　functions　is　proposed.　Then,　the　attribute　weights　and　decision　makers　weights　are　obtained　by　using　the　minimax　method　for　solving　the　model,　and　the　optimal　scheme　is　established.　Finally,　an　example　shows　the　effectiveness　of　the　proposed　method.　©,　2015,　Northeast　University.　All　right　reserved.
