I摘要随着经济全球化的飞速发展和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本身实力，而且需求借助供应链产业中各种各样的服务来实现竞争优势。在这类情况下，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。本研讨先论述了供应链物流网络的构造，接着又研讨了我国供应链物流网络优化时所遇到的问题和挑战，随后又研讨了供应链物流网络优化时的方法、准绳、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以后的效果。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TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc327446734"前言PAGEREF_Toc327446734\h1HYPERLINK\l"_Toc327446735"1研讨的背景及目的PAGEREF_Toc327446735\h3HYPERLINK\l"_Toc327446736"2国内及国外供应链中物流网络的分析PAGEREF_Toc327446736\h5HYPERLINK\l"_Toc327446737"2.1国内供应链中物流网路的分析PAGEREF_Toc327446737\h5HYPERLINK\l"_Toc327446738"2.1.1供应链中物流网络的构造和特点PAGEREF_Toc327446738\h5HYPERLINK\l"_Toc327446739"2.1.2我国供应链中物流网络优化的影响要素PAGEREF_T
