基于双层规划理论的中小城市货运交通网络优化与应用研究摘要本文针对中小城市货运交通运输的发展现状，对货运交通网络的设计、规划、组织与管理进行优化，对于指导中小城市交通运输业的协调发展，全面提高货物的“点对点”运输效率、合理引导货运市场的发展。从中小城市及其货运交通发展的现实问题出发，采用双层规划的理论方法，根据供需平衡关系，协调货运量和货物运输道路之间的关系，灵活的对不同层次的网络优化问题进行深入分析并不断进行货运网络的调整和优化，提出中小城市货运交通网络优化的基本内容和方法，最终构建并完善高效的城市货运交通网络。另外，选取我国典型中小城市张家港市货运交通规划的实例进行研究分析，运用双层规划的原理进行货运网络的布局优化，建立和完善实例城市的货运交通网络，并提出相应的管理措施。关键词：物流管理；双层规划；货运交通；交通枢纽ABSTRACTInthispaper，mediumandsmallurbanfreighttransportdevelopmentstatusofthefreighttransportnetworkdesign，planning，organizationandmanagementoptimization，mediumandsmallcitiesforguidingthecoordinateddevelopmentofthetransportindustry，andcomprehensivelyimprovethegoods"point"transportefficiency，areasonableguidefreightmarketdevelopment.Freighttrafficfromthedevelopmentofmediumandsmallcitiesandtheirpracticalproblemsstarting，usingdouble-planningtheory，basedonthebalancebetweensupplyanddemand，coordinatefreightandcargotransportbetweenroadandflexiblefordifferentlevelsofnetworkoptimizationproblemsindepthandcontinuouslyadjustandoptimizefreightnetwork，smallandmediumurbanfreighttransportnetworkproposedoptimizationbasiccontentandmethods，andultimatelybuildandsoundandefficienturbanfreighttransportnetwork.Inaddition，selectatypicalsmallcityofZhangjiagangCity，instancesoffreighttransportationplanningresearchandanalysis，theuseoftheprincipleofdoublefreightnetworkplanninglayoutoptimization，establishandperfectexamplesofurbanfreighttransportnetwork，andproposeappropriatemanagementmeasures.Keywords：LogisticsManagement；BilevelProgrammingProblem；Freighttraffic；Transportationhub目录基于双层规划理论的中小城市货运交通网络优化与应用研究........1摘要....................................................1ABSTRACT.................................................21、概述.....................................................51.1选题背景.............................................................................................51.2研究意义.............................................................................................61.3国内外研究现状.................................................................................72、中小城市货运交通网络优化内容研究........................112.1我国中小城市货运交通发展现状及趋势的分析............................112.2中小城市货运交通网络优化的要点、原则、方法及目标............122.3资源水平...........................................................................................132.4软件设施货运网络优化...................................................................143、基于双层规划理论的交通网络优化研究......................163.1中小城市货运站场规划...................................................................163.2中小城市货运交通环境规划...........................................................193.3中小城市货运交通的发展趋势.......................................................193.4双层规划理论概论...........................................................................203.5调整交通需求和交通供给供需平衡....................
