【摘要】：工程项目管理是指通过一定的组织形式,用系统工程的理论和方法对工程建设项目的工作进行计划、组织、指挥、协调和控制,以达到保证工程质量、缩短工期、提高投资效益的目的。由此可见,工程项目管理是以工程项目目标控制为核心的管理活动。挣值管理方法是一种有效的集成控制方法,其核心是通过测量已完工作预算费用,在计划和实际之间建立一个桥梁,通过计算项目各个评价指标和预测指标,分析项目成本和进度执行的情况,进而采取相应措施实现项目目标。本论文是结合作者亲历的工程项目,从实践应用的角度出发,重点研究总结了挣值管理中二级挣值法、关键路径挣值法、质量挣值法在中小型化工项目中的运用步骤与要点,旨在为今后的同类项目应用挣值法进行成本、进度控制提供有效的方法和参考的应用流程。本文首先以山西液化天然气项目为研究案例,紧扣该化工项目的实际情况和特点,通过对该工程二级子项目的跟踪检查,整理得到各分项工程的实际成本和进度,应用挣值法分析得出实际执行情况与计划之间的偏差,针对重大偏差采取纠偏措施,从而研究总结出二级挣值法在液化天然气类化工项目成本-进度管理中的具体应用步骤与要点,从本工程实施情况来看,取得了良好的控制效果。其次,以达州液硫装车系统项目为研究案例,计算出该项目的关键与非关键线路,应用关键路径挣值法,分析关键路径上的进度偏差与项目总进度偏差的关系,得出项目进度滞后的原因以及对项目成本的影响情况,从而制定相应的纠偏措施。通过本案例,研究总结出关键路径挣法在化工项目中的应用流程。最后,为了实现挣值法对工程质量的集成管理,将质量挣值法应用于化工管道的安装工程中。即在考虑质量影响因素的前提下,对项目的计划质量水平和实际质量水平进行度量,通过引入质量指数,计算项目质量挣值,并利用挣值法质量指标体系进行偏差分析,从而实现中小型化工项目在工程质量、成本、进度三方面的集成管理。
[Abstract]:Engineering project management refers to the purpose of planning , organizing , directing , coordinating and controlling the work of the engineering construction project by means of the theory and method of system engineering , so as to ensure the engineering quality , shorten the construction period and improve the investment benefit . This thesis is based on the author ' s experience in engineering projects . From the perspective of practical application , the paper summarizes the steps and key points of the application steps and key points of the two - level earned value method , the key path earning value method and the quality - earning value method in the small and medium - sized chemical projects , aiming at providing the effective method and the reference application flow for the future similar projects . Based on the research case of Shanxi liquefied natural gas project and the actual situation and characteristics of the project , the actual cost and progress of each sub - project are obtained . The deviation between the actual execution situation and the plan is obtained by using the earned value method , so as to study the concrete application steps and key points of the two - level earned value method in the cost - schedule management of the liquefied natural gas chemical engineering project . Secondly , the key and non - critical lines of the project are calculated , the key and non - critical lines of the project are calculated , the relationship between the progress deviation on the key path and the total project progress deviation is analyzed by using the key path earning value method , the reasons of the project progress lag and the influence of the project cost are analyzed , and the corresponding corrective measures are worked out . Through the case , the application flow of the key path earning method in the chemical engineering project is summarized . In the end , in order to realize the integrated management of the earned value method to the engineering quality , the quality earned value method is applied to the installation project of the chemical pipeline . In other words , the quality level and the actual quality level of the project are measured under the premise of considering the quality influence factors . By introducing the quality index , the quality of the project is calculated , and the deviation analysis is carried out by using the earning value method quality index system , so as to realize the integrated management of the small and medium chemical projects in the engineering quality , cost and progress .
