Research On Cost Control Of R Project Based On Earned Value Method

With a large number of Chinese engineering enterprises going to the world,the bid price of international infrastructure projects is getting lower and lower,and the pressure on profitability is increasing.The cost fine management of each company is becoming more and more important.The level of project cost management has gradually become the key to the success or failure of the project.Z company is a real estate construction enterprise with overseas engineering construction as its main business.It has long applied master format and general ledger systems to make cost and progress statistics,and controlled the cost of projects at all levels through earned value method,cost allocation and other tools.On the other hand,the application of earned value method in Z company is not in-depth.Earned value analysis is only used as a data statistical tool and is not really applied to the management process.In practice,it mainly relies on the experience of managers for cost control,which can greatly improve the accuracy and granularity of control.In order to improve the level of cost management,Z company must realize fine cost control through digital alternative experience,better apply the earned value method as a cost management tool,and control the cost and progress through scientific methods.However,at present,there are many problems in the application of earned value analysis in Z company,and it must be transformed suitable for the actual project.The author is the project manager of R Project.The project cost is about 1.4 billion yuan.The main project contents include road engineering,interchange,pedestrian overpass,etc.The market environment,project form,project volume and project construction complexity of the project are very suitable for the implementation,verification and improvement analysis of the earned value method.It is suitable for Z company to optimize the earned value analysis.Therefore,aiming at the shortcomings of Z company’s earned value analysis,this paper introduces the key chain method and two-level earned value method,and puts forward an improved earned value method to optimize the cost management of Z company.The main work includes: introducing the two-level earned value method to make the earned value analysis finer,reduce the internal progress of the project,offset each other,and clarify the actual progress of the project;Combining the key chain technology with earned value method,the key chain is defined and the schedule is adjusted;The concept of resource buffer is introduced,and the earned value detection point is set at the resource buffer,so that the earned value analysis can meet the reality of project management and better reflect the actual situation of the project.Through the above three aspects,the earned value analysis is closer to the actual needs of Z company,and the effective control of project cost and progress is realized.
