【摘要】：隨著現(xiàn)代社會(huì)經(jīng)濟(jì)的快速發(fā)展,建設(shè)工程項(xiàng)目越來(lái)越多,規(guī)模也越來(lái)越大,工程項(xiàng)目管理的內(nèi)容也在不斷的完善,項(xiàng)目進(jìn)度管理作為工程項(xiàng)目管理中的一項(xiàng)非常重要的工作,能全面反映項(xiàng)目的實(shí)施情況,其重要性越來(lái)越突出,也對(duì)項(xiàng)目進(jìn)度管理的方法,提出了更高的要求。工程進(jìn)度管理對(duì)于企業(yè)而言,都是獲得經(jīng)濟(jì)效益的有力保證。每個(gè)建設(shè)項(xiàng)目,在建設(shè)期間都要投入大量的財(cái)力,并承擔(dān)著巨大的財(cái)務(wù)壓力和資金回收的風(fēng)險(xiǎn)。所以,工程早日完成投入使用,就能夠早日產(chǎn)生效益。作為施工企業(yè),在合同簽訂之后,在不發(fā)生重大施工內(nèi)容變更的前提下,如果想獲得相對(duì)更多的經(jīng)濟(jì)效益,就必須通過(guò)科學(xué)的管理方法,而工程進(jìn)度管理就是合理獲得良好經(jīng)濟(jì)效益的有效和直接手段[1]。如何進(jìn)一步控制工期,節(jié)省資源,節(jié)約工程項(xiàng)目的投資,是目前廣大項(xiàng)目管理者普遍關(guān)注的問(wèn)題。施工單位是控制施工進(jìn)度計(jì)劃的主體,需要對(duì)影響進(jìn)度計(jì)劃的因素進(jìn)行分析調(diào)查,預(yù)測(cè)各項(xiàng)因素對(duì)進(jìn)度的影響,指導(dǎo)工程項(xiàng)目的進(jìn)度計(jì)劃實(shí)施,保證進(jìn)度控制。編制項(xiàng)目進(jìn)度計(jì)劃是項(xiàng)目管理工作中的重點(diǎn)內(nèi)容,能全面反映一個(gè)工程項(xiàng)目的實(shí)施情況。在施工階段做好進(jìn)度管理,對(duì)確保工程按期完工起著重要的作用。傳統(tǒng)的網(wǎng)絡(luò)進(jìn)度計(jì)劃,因?yàn)榭紤]到工程施工過(guò)程中存在很多的不確定因素,其活動(dòng)實(shí)施時(shí)間也不能完全確定,所以在確定網(wǎng)絡(luò)進(jìn)度計(jì)劃時(shí)間參數(shù)的時(shí)候采用的是計(jì)劃評(píng)審法(PERT),時(shí)間參數(shù)的確定是利用有經(jīng)驗(yàn)的技術(shù)人員對(duì)每個(gè)事件進(jìn)行工期的大致估計(jì),通過(guò)確定最樂(lè)觀時(shí)間、最悲觀時(shí)間和最可能時(shí)間。在時(shí)間參數(shù)的估計(jì)中,傳統(tǒng)的網(wǎng)絡(luò)進(jìn)度計(jì)劃采用的是最悲觀時(shí)間。這樣使工程的整體進(jìn)度較長(zhǎng),資源占用量大,從而使工程成本也較高。通過(guò)對(duì)傳統(tǒng)網(wǎng)絡(luò)進(jìn)度計(jì)劃的分析,可以看出要想獲得良好的經(jīng)濟(jì)效益就要保證合理工期,改進(jìn)后的網(wǎng)絡(luò)進(jìn)度計(jì)劃在確定時(shí)間參數(shù)的時(shí)候采用最樂(lè)觀時(shí)間。與傳統(tǒng)網(wǎng)絡(luò)進(jìn)度計(jì)劃相比,具有施工工期短,費(fèi)用節(jié)約等優(yōu)勢(shì),早投產(chǎn)早使用,搶占先機(jī)取得良好的經(jīng)濟(jì)效益和社會(huì)效益。
[Abstract]:With the rapid development of modern society and economy, more and more construction projects have been built, and the contents of project management have been continuously improved. Project schedule management is a very important work in engineering project management. It is more and more important to reflect the implementation of the project, and it also puts forward higher requirements for the method of project schedule management. Project schedule management is an effective guarantee for enterprises to obtain economic benefits. Every construction project has to invest a lot of financial resources during the construction period, and bear the huge financial pressure and the risk of capital recovery. Therefore, the early completion of the project into use, will be able to produce early benefits. As a construction enterprise, after the signing of the contract and without major changes in construction content, if we want to obtain relatively more economic benefits, we must adopt scientific management methods. The project schedule management is an effective and direct means to obtain good economic benefits reasonably [1]. How to further control the duration of the project, save resources and save the investment of the project is a common concern of the project managers at present. The construction unit is the main body of the construction schedule control, it is necessary to analyze and investigate the factors that affect the progress plan, predict the influence of each factor on the progress, guide the implementation of the project schedule plan, and ensure the schedule control. Drawing up project schedule is an important part of project management, which can reflect the implementation of a project. It plays an important role in ensuring the completion of the project on schedule by doing the schedule management well in the construction stage. The traditional network schedule, because there are many uncertain factors in the construction process, the implementation time of its activities can not be fully determined. Therefore, in determining the network schedule planning time parameters, we use the plan review method (PERT), time parameters determination is to use experienced technicians to estimate the duration of each event roughly, by determining the most optimistic time. The most pessimistic time and the most likely time. In the estimation of time parameters, the most pessimistic time is used in the traditional network schedule. In this way, the overall progress of the project is long, the amount of resources is large, and the cost of the project is higher. Through the analysis of the traditional network schedule, we can see that if we want to obtain good economic benefits, we must ensure a reasonable time limit, and the improved network schedule adopts the most optimistic time when determining the time parameters. Compared with the traditional network schedule, it has the advantages of short construction period, cost saving and so on.
