Yun Tian, Ying-ying Yuan, Jinlong Cao, Yiyong Xiao · 2013
The supervision of Complex equipment development (CED) projects is facing a lot of challenges in scheduling and cost control.In this paper, we presented a dynamic earned value management (DEVM) model based on mathematical programming for the real-time forecast of schedule/cost of CED projects.A similarity matrix of the items was introduced into the model to improve the accuracy of the forecasts.Moreover, we proposed a practical technique called Four-quadrant Diagram of Schedule-Cost to dynamically visualize the performances of a CED project, and a new index named Earned Value Divergence to evaluate to what degree the project is controlled.Finally, a case study was provided to illustrate the performance of this method.
