Mang large-scale techical equipment projects are being developed and constructed in various departments of this country. "Ihe theory and method of systems science have found successful application and development in the management of large-scale technical equipment projects.1. Optimum alternative of project programme and system of project management organization;2. Planning control subsystem.. Analysis of system, system process and system model;3. Quality control system: First, technical problem; second, the problem of management;4. project management information system.The whole system shows that, along with the development of machining, and the continuous extension and deepenning of the information inside the system, the circuit of production management information comes into being. Furthermore, the information circuit is a combination of the computer and man. It plays a very importent role in the project management.
