The entire process cost control sys

The entire process cost control system is based on system theory, value engineering and cybernetics models described in Chapter 2. First, the principles of system theory are adopted in the project decision stage. In the process of project feasibility study, the costs are analyzed, determined, determined and controlled according to the integrity, optimization, dynamics, comprehensiveness and modeling characteristics of the system theory. Second, the principles of system theory and value engineering are applied during the design phase of the project. Using system theory, grasp the key points and balance of the design under the overall situation, and select the optimal design plan according to the optimization principle of value engineering to control the cost. Third, in the project bidding phase, the principle of value engineering is adopted, and the optimal contracting scheme is selected to control the cost. The first shower, using the principles of system theory, cybernetics, and value engineering in the project construction phase, grasp the whole, and select the optimal solution, such as problems, information feedback, problem solving, to control costs; fifth, the use of control On the principle of system theory, in the completion of the settlement stage, the end of project cost is obtained, the final step of construction cost control is realized, and the experience of project cost control is summarized to provide reference for project cost control.
