Li,　S.;　Sun,　Q.,　and　Wu,　W.,　2019.　Benefit　distribution　method　of　coastal　port　intelligent　logistics　supply　chain　under　cloud　computing.　In:　Guido-Aldana,　P.A.　and　Mulahasan,　S.　(eds.),　Advances　in　Water　Resources　and　Exploration.　Journal　of　Coastal　Research,　Special　Issue　No.　93,　pp.　1041-1046.　Coconut　Creek　(Florida),　ISSN　0749-0208.　In　order　to　improve　the　benefit　distribution　planning　ability　of　coastal　port　intelligent　logistics　supply　chain　under　cloud　computing,　a　benefit　distribution　model　of　coastal　port　intelligent　logistics　supply　chain　based　on　intelligent　bionic　group　evolutionary　optimization　control　is　proposed.　The　distributed　node　deployment　model　of　coastal　port　intelligent　logistics　supply　chain　under　cloud　computing　is　constructed,　and　the　optimal　path　planning　and　design　of　coastal　port　intelligent　logistics　supply　chain　network　is　carried　out　by　using　the　least　square　programming　method.　The　fuzzy　decision　statistical　characteristics　of　coastal　port　intelligent　logistics　supply　chain　path　output　under　cloud　computing　are　extracted,　and　the　benefit　distribution　model　of　coastal　port　intelligent　logistics　supply　chain　under　cloud　computing　is　constructed　by　combining　adaptive　decision　optimization　control　method.　The　intelligent　bionic　group　evolutionary　optimization　algorithm　is　used　to　realize　the　adaptive　planning　and　design　of　coastal　port　intelligent　logistics　supply　chain　under　cloud　computing,　and　the　optimal　benefit　distribution　and　control　of　coastal　port　intelligent　logistics　supply　chain　under　cloud　computing　are　realized.　The　simulation　results　show　that　the　resource　consumption　of　coastal　port　intelligent　logistics　supply　chain　planning　under　cloud　computing　is　small　and　the　spatial　planning　ability　is　strong,　which　improves　the　scheduling　path　optimization　and　intelligent　control　ability　of　coastal　port　intelligent　logistics　supply　chain.　©　Coastal　Education　and　Research　Foundation,　Inc.　2019.
