【摘要】：中國經(jīng)濟的高速發(fā)展帶來了建筑業(yè)市場的興盛繁榮,而施工企業(yè)良好的進度和成本控制成為其占領市場的制勝法寶。傳統(tǒng)的掙值管理方法可以對項目成本和進度進行監(jiān)控,反映項目的執(zhí)行效果,但是無法準確識別項目實施過程中出現(xiàn)的異常變化及偏差的可接受水平,判斷項目是否處于可控范圍內(nèi)。利用統(tǒng)計過程控制理論中的控制圖方法可以有效監(jiān)控項目實施過程掙值指數(shù)的波動情況,監(jiān)測引起波動的偏差是否處于可接受水平,保證項目在穩(wěn)定狀態(tài)下的實施。本文將統(tǒng)計過程控制圖與傳統(tǒng)的掙值管理方法相結(jié)合,通過對掙值理論和統(tǒng)計過程控制理論等相關基礎的梳理,選定單值-移動極差控制圖(I-MR控制圖)進行建設項目掙值指數(shù)的監(jiān)控,計算I-MR控制圖的控制界限,并對獲得的數(shù)據(jù)進行正態(tài)性檢驗,給出非正態(tài)分布的樣本數(shù)據(jù)的正態(tài)性轉(zhuǎn)換方法,提出I-MR控制圖在掙值方法中的實施步驟以及成本、進度偏差的控制方法。最后對某棚戶區(qū)改造工程進行實例研究,驗證基于I-MR控制圖進行項目掙值績效(進度績效指數(shù)SPI和成本績效指數(shù)CPI)管理的可能性。這種方法能夠為項目成本、進度提供實時監(jiān)控和及時預警,改善傳統(tǒng)掙值方法無法識別項目實施過程中微小變化的缺陷,提高項目掙值指數(shù)的監(jiān)控能力,為項目管理人員及時提供準確信息,采取措施使項目維持在穩(wěn)定狀態(tài)內(nèi),保證項目的順利完成。
[Abstract]:The rapid development of Chinese economy has brought about the prosperity of the construction market, and the good progress and cost control of the construction enterprises have become the magic weapon to occupy the market. The traditional earned value management method can monitor the project cost and progress and reflect the effect of the project implementation, but it can not accurately identify the abnormal changes and the acceptable level of deviation in the process of project implementation. Determine whether the item is under control. By using the control chart method in the statistical process control theory, the fluctuation of earned value index in the project implementation process can be effectively monitored, the deviation caused by the fluctuation can be monitored at an acceptable level, and the implementation of the project in a stable state can be ensured. This paper combines the statistical process control chart with the traditional earned value management method and combs the relevant foundation of earned value theory and statistical process control theory. Single value-moving range control chart (I-MR control chart) is selected to monitor the earning value index of construction project, calculate the control limit of I-MR control chart, and test the normality of the obtained data. In this paper, the normality transformation method of non-normal distribution sample data is given, and the implementation steps of I-MR control chart in earned value method as well as the control method of cost and schedule deviation are presented. Finally, a case study of a shantytown renovation project is carried out to verify the possibility of project earning performance (progress performance index SPI and cost performance index SPI) management based on I-MR control chart. This method can provide real-time monitoring and timely warning for project cost and progress, improve the traditional earned value method can not identify the defects of small changes in the implementation of the project, and improve the monitoring ability of project earned value index. Provide timely and accurate information for the project manager, take measures to keep the project in a stable state and ensure the smooth completion of the project.
