Under　the　conditions　of　modern　market　economy　and　the　increasing　pressure　of　competition,　a　growing　number　of　product　life　cycles　are　getting　shorter,　customer　demand　is　constantly　changing,　this　force　the　companies　began　to　pay　attention　to　their　own　internal　management　and　supply　chain　management.　Supply　chain　refers　to　the　suppliers,　manufacturers,　distributors　and　end-users,　and　the　network,　which　design　both　directions　of　material　flow,　information　flow　and　capital　flow　[1].　In　order　to　manage　and　use　it　better,　People　put　network　information　technology　in　supply　chain　management,　developed　or　purchased　ERP　implementation　systems　software,　thus　can　share　information　between　departments　and　enterprises.　But　problems　have　gradually　exposed,　faster　access　and　processing　does　not　produce　a　good　decision　automatically.　So　this　paper　under　the　premise　of　uncertainty,　started　studying　supply　chain＇s　network　model,　establishing　optimization　model,　design　algorithms,　therefore　reducing　the　total　costs,　to　avoid　risks.
