摘要随着经济全球化的飞速发展以及全球市场化的逐渐深化，供应链的竞争逐渐成为新时期产业竞争的关键内容。企业的成败不但取决于它自身实力，而且需要借助供应链产业中各种各样的服务来实现竞争优势。在这种情况下，我们有必要找出合适的供应链物流网络优化模型来降低企业亏损并提高效益。本研究先论述了供应链物流网络的构造，接着又研究了我国供应链物流网络优化时所遇到的问题和挑战，随后又研究了供应链物流网络优化时的方法、原则、和步骤，然后又以德邦物流公司为例，用遗传算法对德邦物流济南分公司进行了物流网络优化，并用数据进行了验证，又分析了公司在优化之后的效果。通过对供应链物流网络优化模型的认识能够为企业改革者提供一些新的决策依据，提高企业的工作效率，降低运营成本。关键字：供应链物流网路，优化模型，德邦物流公司，遗传算法，成本优化AbstractFollowingwiththerapiddevelopmentofworldeconomyandthestrongimprovementofeconomicalglobalization,Competitioninthesupplychainisbecomingakeyelementoftheneweraofindustrialcompetition.Corporatesuccessorfailuredependsnotonlyonitsownstrength,andtheneedtouseavarietyofservicestoachievecompetitiveadvantageinthesupplychainindustry.Inthiscase,weneedtofindtherightsupplychainlogisticsnetworkoptimizationmodeltoreducelossesandimproveefficiency.wefirststudythestructureofthesupplychainlogisticsnetwork,andthenstudytheproblemsandchallengesencounteredinthesupplychainlogisticsnetworkoptimization,followedbyafterthesupplychainlogisticsnetworkoptimizationmethod,Principles,andsteps.Then,byDebonlogisticscompanies,forexample,weusegeneticalgorithmstooptimizeDebonlogisticsJinanbranch,andthenwegetthedatavalidation,analysisoftheeffectofthecompanyaftertheoptimization.Understandingthroughthesupplychainlogisticsnetworkoptimizationmodelforcorporatereformerstoprovidesomebasisfordecisionmaking,improvingtheworkefficiency,reduceoperatingcosts.Keywords:Supplychainlogisticsnetwork,Geneticalgorithm,Optimizationmodel,Debonlogisticscompany,CostsoptimizationI目录前言....................................................................11研究的背景及目的.........................................................32国内及国外供应链中物流网络的分析.........................................52.1国内供应链中物流网路的分析.........................................52.1.1供应链中物流网络的构造以及特点...............................52.1.2我国供应链中物流网络优化的影响因素........................72.1.3我国供应链中物流网络优化遇到的挑战............................72.2国外供应链中物流网路模型的分析.....................................92.2.1美国的供应链中物流网络模型的分析.............................92.2.2日本的供应链中物流网络模型的分析..............................92.2.3欧洲的供应链中物流网络模型的分析.............................103供应链中物流网络的优化..................................................133.1供应链中物流网络的优化原则........................................133.2供链中物流网络的优化方法..........................................133.3供应链中物流网络的优化程序........................................144以德邦公司为例的物流网络的优化模型......................................194.1德邦物流公司在物流网络方面的缺陷..................................194.2优化模型的建立....................................................194.3对优化模型进行求解................................................194.3.1遗传基因算法的简介...........................................204.3.2利用遗传基因算法求解德邦物流公司的网络优化问题.................
