Research And Application Of Multi - Factor Earned Value Management Method In Engineering Project

Cost management is the core of the construction management of building construction enterprise eternal research content, is also the subject of construction enterprises. In the process of the whole life cycle of construction project, fine management, project cost management is the key factor of the success of the project management, is an important management job through all phases of the project life cycle, project construction success or failure to bad directly affect the level of the management, the management level of the effect. However, the current construction enterprises of our country exists generally in the low level of cost management, extensive management, the cost is high, the poor economic problems, especially the specification of the engineering quantity list valuation generally implemented in the country, to the cost management of construction enterprises has brought a more serious challenge.Earn value management theory of the source of law based on statistics, its existence in the origin (quantities) priority assumption. At the same time, earned value management will be integrated project management is simplified as a multi factor time and cost two factors integrated management. The Earned Value Management in abandoned the joint influence of engineering quantity and price factors, so its application in actual cost management also exist many problemsThis paper on the comprehensive index analysis method and the traditional method of earned value analysis, find out the deficiency, through the introduction of LMDI decomposition method, considering many factors which influence the amount of the assignment problem, combined with the actual situation of the project cost control, the cost control in the unit price factor decomposition, which factors of product of LMDI decomposition model and factors and factors of product hybrid forms of LMDI decomposition model is constructed, and on the basis of the traditional earned value method was improved on, through multiple examples verify the LMDI decomposition method to improve the multi factors of earned value method based on the validity and accuracy of the proposed.
