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IAbstractInternetplanisatechniquethatdemonstrateseachtask,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;optimizationofinternetplanII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...........................................
