Abstrac At present, China's economic construction is in a period of rapid development, national development strategies from the perspective of structural adjustment of economic policies and investment, construction faced with good opportunities for development, the market is vast. Rapid economic development is incompatible with the contradiction between the market mechanism is reflected in the construction projects focused on the key issue is that perfect sound project management methods, and promote the development of secondary industry in China. In recent decades, modern project management theory in modern science and technology and management, in particular, information theory, cybernetics, systems theory, computer technology and operational research and development on the basis of it, and the practice of modern engineering project astounding results. The universality of the project management and the important role of social development, its research and applications are increasingly subject to many governments, business and industry wide attention. Our project management in many engineering, technical, and management has been applied in the supervision of engineers, cost engineers, project managers in training and professional qualification tests involve the content of project management. As projects and systematic project management, complexity, and makes all kinds of technical work, management and functions of the work of a growing tendency to overlapping between the mutual influence and constraints, among them the existence of complex division of labor and cooperation relationship, so we properly handle the impact of factors among them, continue to sum up from the practice of a variety of scientific management methods and means to better adapt to the country's economic construction, scientific and technological progress and social development.
