To　reflect　the　uncertainty　and　fuzziness　during　the　process　of　supply　chain　information　sharing　synthetically　more　felicitously,　a　quadratic　programming　model　based　on　the　optimal　integrative　degree　of　enterprises＇　satisfaction　in　the　supply　chain　with　least　square　method　was　constructed　for　solving　cooperative　games　with　coalition　values　expressed　by　triangular　intuitionistic　fuzzy　numbers.　On　this　basis,　the　lower,　mean　and　upper　bounds　of　triangular　intuitionistic　fuzzy　number　payoff　of　each　player　were　easily　computed.　Moreover,　according　to　the　improved　algebraic　operations,　the　membership　degree　and　nonmembership　degrees　of　triangular　intuitionistic　fuzzy　number　payoff　of　each　player　were　obtained.　A　numerical　example　was　given　to　illustrate　the　proposed　models　and　method,　and　the　result　showed　that　the　information　distortion　and　the　uncertainty　amplification　could　be　effectively　avoided　by　considering　the　triangular　intuitionistic　fuzzy　number　optimal　allocation　and　its　membership　degree　and　non-membership　degree.　©　2018,　Editorial　Department　of　CIMS.　All　right　reserved.
