The　operating　system　is　a　complex　system　that　includes　supply　and　demand.　Changes　in　external　information　have　an　impact　on　the　operation　of　the　system,　especially　on　both　supply　and　demand.　This　paper　analyzes　the　supply　and　demand　and　establishes　the　nonlinear　programming　problem　of　system　operation　under　the　social　optimal　goal.　With　the　increase　of　external　information　intervention,　there　will　be　more　suitable　travel　fares　for　the　demand　side.　However,　the　supply　side＇s　related　operating　indicators　(for　example,　frequency,　bus　fleet,　and　vehicle　capacity,　etc.)　have　shown　a　trend　of　first　increasing　and　then　decreasing　due　to　existing　resource　constraints.　It　can　be　seen　that　under　the　same　information　interference,　there　are　differences　in　the　law　of　change　between　the　supply　and　demand　sides.　Besides,　an　example　is　used　to　verify　the　effectiveness　of　the　model.　Through　the　model　and　calculation　examples,　we　can　know　that　the　supplier　and　the　demander　can　meet　their　own　needs　under　the　social　optimal　goal.　This　provides　certain　theoretical　support　for　future　research　information　on　system　operation.　©　2020　Journal　of　Physics:　Conference　Series.
