上海领鲜冷链物流配送路线优化研究摘要历史潮流的推进，社会也在发展，冷链物流逐渐慢慢兴起。但是冷链产品十分特殊，具有相当高的保存要求，所以对于冷链物流的配送线路规划也有十分高的要求。为了保证冷链产品的品质，需要将各种因素都一一考虑，最后综合起来得出一个较完美的解决方案。广州是一个国际大都市，人口众多，经济发达，对于冷链产品需求大。目前，上海领鲜物流在广州只有一家配送中心，但是想要很好的发展冷链物流，一家配送中心是远远不够的，完全不能满足冷链业务的实际情况。所以，本文将广州现有的配送中心作为一级配送中心，然后在11个区分别选址作为二级配送中心，然后对两者之间进行路线上的研究。最后，通过建立VRP模型，运用蚁群算法和MATLAB求解，得到最优路径和最小成本。建立完善的冷链物流运作体系，对于冷鲜而言将大大增加自身的盈利能力。运用实例求解的结果表明，本文所建模型对冷链物流车辆路径优化及控制成本是可行且有效的，保障了冷链食品在运输过程的新鲜度，降低了物流的运输成本和损耗成本，可为相关企业在决策时提供可参考的理论依据[1]。【关键词】:冷链物流；蚁群算法；MATLABStudyonOptimizationofLogisticsDistributionRoutesinShanghaiAbstractThetrendoftheadvancementofhistory,societyisalsodeveloping,coldchainlogisticsgraduallyslowlyrising.Butthecoldchainproductsareveryspecial,withaveryhighpreservationrequirements,soforthecoldchainlogisticsdistributionlineplanningalsohasaveryhighdemand.Inordertoensurethequalityofcoldchainproducts,needtoconsiderallkindsoffactorsonebyone,andfinallytogethertocomeupwithamoreperfectsolution.Guangzhouisaninternationalmetropolis,alargepopulation,economicdevelopment,demandforcoldchainproducts.Atpresent,theShanghaifreshlogisticsinGuangzhou,onlyonedistributioncenter,butwantagooddevelopmentofcoldchainlogistics,adistributioncenterisnotenough,cannotmeettheactualsituationofcoldchainbusiness.Therefore,thispaperwillbetheexistingdistributioncenterinGuangzhouasadistributioncenter,andthenin11districtswereselectedasasecondarydistributioncenter,andthenbetweenthetwoonthelineofresearch.Finally,byestablishingtheVRPmodel,theantcolonyalgorithmandMATLABareusedtogettheoptimalpathandtheminimumcost.Establishaperfectcoldchainlogisticsoperationsystem,forthecoldwillgreatlyincreasetheirprofitability.Theresultsoftheexampleareusedtoshowthatthemodelproposedinthispaperisfeasibleandeffectivefortheoptimizationandcontrolofthecoldchainlogisticsvehiclepath.Itensuresthefreshnessofthecoldchainfoodduringtransportationandreducesthetransportationcostandcostofthelogistics.Fortherelevantenterprisesinthedecision-makingtoprovideatheoreticalbasisforreference.【Keywords】:coldchainlogistics;antcolonyalgorithm;matlab目录一．绪论..........................................................................................................................................1（一）研究背景、目的与意义...............................................................................................1（二）国内外研究综述...........................................................................................................2二．上海领鲜物流概述...................................................................................................................3（一）上海领鲜物流简介.......................................................................................................3（二）上海领鲜物流在广州地区的发展状况.......................................................................3（三）领鲜物流城市末端配送广州地区存在的问题......................
