Abstract: Based on the summary of construction characteristics of subway electromechanical project, according to the actual problems of the Jinbin subway project of western section of Zhongshanmen, complex system theories (Earned Value Management (EVM), Cost-significant(CS), Back-Propagation Neural Network (BPNN), Gray model (GM) ), virtual reality techniques and dynamic optimized management technique were applied in the process of construction management. The corresponding virtual dynamic optimized management system was developed to realize the virtual visualization management of the project. Before the subway construction, the virtual static optimized management system was set up, which had the characteristics of multi-work, multi-professional, multi-coordination, mutual intercrossing and paralleling, multi-dimension and multi-interference. In the process of subway construction, the dynamic optimized management system was established to focus on the key control project to carry out EVM analysis and PDCA cycle control. The existed problems were analyzed and the data repository of control measures was established, which was convenient for construction management and decision-making, so as to realize the scientific and informatization management.
