Application and Implementation of Earned Value Method in Project Cost Management System

Cost control is one of the three control objectives in project engineering.Earned Value Method is an effective method of cost control.Based on the application of contract management,estimate management and project investment analysis module in the project cost management system this paper,calculates and disposes the three cost value in Earned Value Method through system database design and algorithm design,and describes the Earned Value curve,realizes the application of Earned Value Method in cost management system,thereby achieves the decision support functions of conducting comprehensive analysis and predicts to the project cost operation situation.
