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.
