Based On The Earned Value Method Of WL Company Project Cost Control Research

The current our country construction enterprise project high production cost,resource waste,there is no guarantee that the phenomenon of project quality,is not conducive to the healthy development of enterprises.Therefore,effective cost control is very necessary,its main purpose is to ensure the quality of the premise,reduce project costs,reasonable allocation of resources,make the enterprise gains the best and the biggest profits.Taking WL company as the research object,this paper analyzes the problems of project cost management by theoretical demonstration and example analysis,and finds out that the company is lack of system in cost management process,cost control method is imperfect,project cost and schedule control are separated,and the cost supervision is weak,which lead to project cost much more than budget cost,multiple project losses,which not only affect the business efficiency of enterprises,but also weaken the competitiveness of enterprises.According to the problem analysis,based on the experience of the cost control at home and abroad,in combination with the practical situation of company and project,puts forward corresponding proposals.Combine the original project budget law earned value method applied to the actual project,reasonable distribution of project structure,clear management responsibilities,in accordance with the progress of the preparation of cost plan,finally,earned value method is introduced,using the parameters of the earned value method to calculate the cost of the project schedule and deviation,this paper analyzes the reasons of deviation,timely and accurate adjustment of the follow-up project schedule.Judgment so as to avoid the risk of cost control,cost control effectiveness,ensure the progress of the completion,the project management of scientific and rational resource allocation management,ensure the construction smoothly,but also provides the construction enterprises cost control management.
