School of Mechanical Engineering and Automation, Beijing University of Aeronautics and Astronautics， Beijing 100083, China；2.School of Mechanical and Vehicle Engineering, Beijing University of Technology，Beijing 100081, China) Abstract: The paper conducted research on the Earned Value Method application in the management process of defense-type engineering projects, assisted project managers to make integrated monitoring about project schedule and cost. Meanwhile, the method was improved to overcome its disadvantage in the analysis on project quality effect factors, adding three quality-cost parameters based on cost limited control method. The three parameters are QBCWS (Quality Budgeted Cost for Work Scheduled), QACWP (Quality Actual Cost for Work Performed), QBCWP (Quality Budgeted Cost for Work Performed). By using the three additional parameters, four project quality estimation indexes were further developed，including QCV (Quality Cost Variance), QSV (Quality Schedule Variance), QCPI (Quality Cost Performed Index) and QSCPI (Quality Schedule Cost Performed Index, enriched the parameter and index system of the Earned Value Method. The improved method can monitor project quality, cost and schedule comprehensively. Its efficiency in the application of integrated project monitoring was illustrated with an example of engineering project management process, and better analysis results were obtained.
