【摘要】：中国经济的高速发展带来了建筑业市场的兴盛繁荣,而施工企业良好的进度和成本控制成为其占领市场的制胜法宝。传统的挣值管理方法可以对项目成本和进度进行监控,反映项目的执行效果,但是无法准确识别项目实施过程中出现的异常变化及偏差的可接受水平,判断项目是否处于可控范围内。利用统计过程控制理论中的控制图方法可以有效监控项目实施过程挣值指数的波动情况,监测引起波动的偏差是否处于可接受水平,保证项目在稳定状态下的实施。本文将统计过程控制图与传统的挣值管理方法相结合,通过对挣值理论和统计过程控制理论等相关基础的梳理,选定单值-移动极差控制图(I-MR控制图)进行建设项目挣值指数的监控,计算I-MR控制图的控制界限,并对获得的数据进行正态性检验,给出非正态分布的样本数据的正态性转换方法,提出I-MR控制图在挣值方法中的实施步骤以及成本、进度偏差的控制方法。最后对某棚户区改造工程进行实例研究,验证基于I-MR控制图进行项目挣值绩效(进度绩效指数SPI和成本绩效指数CPI)管理的可能性。这种方法能够为项目成本、进度提供实时监控和及时预警,改善传统挣值方法无法识别项目实施过程中微小变化的缺陷,提高项目挣值指数的监控能力,为项目管理人员及时提供准确信息,采取措施使项目维持在稳定状态内,保证项目的顺利完成。
[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.
