I摘要网络计划是借助于网络表示各项工作和所需时间，以及各项工作之间关系的一种技术。网络计划技术是一项科学的施工管理思想、方法和手段，它的应用不仅是一个技术问题，还涉及到项目管理体制和同项目有关的单位、个人等多方面的因素。施工企业网络技术应用水平的提高，除了要尽快规范建筑管理体制，并制定有效的措施提高企业应用网络技术的积极性之外，更重要的是企业自身要提高市场竞争力，而工程人员要通过全面实施网络技术来促进企业的管理水平.在经过网络分析以后，要研究的是工程费用与工期之间的相互关系，并且要找出在编制计划以及在计划执行过程中的关键路线。本人通过对东莞桥头项目开工设计和前期工作进行实例考证,对楼盘开发的最优工期计划进行研究。通过网络计划得出关键线路，再经过关键线路的计算得出总工期的时间。然后对网络计划进行时间优化，计算这个工程项目能够缩短的工期时间及增加的费用，得出最短工期。关键词：网络计划技术；网络图；关键线路；网络计划优化AbstractInternetplanisatechniquethatdemonstrateseachtask,theneededtime,andtherelationsbetweendifferenttasks,withthehelpofinternet.Networkprogramtechniqueisascientificandsystematicdevicewhichisappliedtoconstructionmanagement.It’snotonlyamatteroftechnique,butalsoinvolvesthesystemsofprojectmanagement,thecorporationandthestaffoftheproject,etc.Inordertoimprovenetworktechnologyofconstructionalcorporation,effectivemeasuresneedtobetakentoboosttheinitiativeofdevelopingcorporationnetworktechnologyandtoperfecttheconstructionmanagementsystems.Moreimportantly,thecorporationisrequiredtoenhanceitsownmarketcompetitiveness,andthestaffareurgedtoutilizewidelynetworktechnologysoastopromotethemanagementlevelofthecorporation.Throughonlineanalysis,peoplecangainaclueoftherelationshipbetweenengineeringcostandtimelimitforaproject.Itcanbeusedtofindoutthekeyroutineofexecutingtheplan.ByexaminingthebuildingopeningdesignofDongguanBridgeanditspreparation,thearticlestudiesthebesttimeallocationforbuildingproject,andtakestheadvantageofinternetplantooptimizethesophisticatedtime.Eventually,bycalculatingthefinaltimelimitandtheaddedcost,theminimumtimelimitcouldbefoundout.Keywords:Networkprogramtechnique；NetworkGraph；Keyroutine；optimizationofinternetplan目录摘要..........................................................................................................................IAbstract.....................................................................................................................II1课题研究的意义和论文的论证思路...................................................................11.1选择网路计划技术课题的原因........................................................................11.2利用网络计划技术进行网络分析的项目介绍................................................11.3网络计划技术的研究意义................................................................................11.4论文的论证思路................................................................................................21.4.1确定目标.........................................................................................................21.4.2分解工程项目，列出作业明细表.................................................................21.4.3绘制网络图，进行结点编号..........................................................................21.4.4计算网络时间，确定关键路线......................................................................31.4.5进行网络计划方案的优化..............................................................................31.4.6网络计划的贯彻执行......................................................................................32网络计划技术的概况及其与建筑工程的关系...................................................52.1网络计划技术的定义........................................................................................52.2网络计划的基本原理........................................................................................52.3网络计划技术简介............................................................................................52.4国内外网络计划技术应用现状........................................................................62.4.1国外应用网络计划技术现状.........................................................................62.4.2国内应用网络计划技术的现状.....................................................................62.5关于对我国企业应用网络计划技术应用中的一些建议................................72.6建筑工程与网路计划技术的关系....................................................................73东莞桥头项目施工准备阶段主要工作介绍.......................................................93.1围蔽前的准备工作............................................................................................93.2申报临水临电....................................................................................................93.3现场查勘，进一步清理场地............................................................................93.4工程部组织详勘..............................................................................................103.5项目分区开发综合计划...................................................................................103.6图纸会审..........................................................................................................113.7“三通一平”的实施...........................................................................................113.8编制项目总进度节点控制计划......................................................................123.9编制现场工程师工作细则..............................................................................133.10前期的其他准备工作....................................................................................134东莞桥头项目的网络分析.................................................................................154.1确定目标.................................................................................................
