Coordination of Construction Project Cost and Schedule Based on Grey Forecasting Method

In the premise of quality establishment, cost control and schedule control are the major goals of the construction project management. This paper is based on grey system theory as the foundation, and uses the grey control method to realize the cost and schedule control and establishes the coordination of GM (1, 1) prediction model, which is the core of the system. The GM (1, 1) grey forecasting model and network planning optimization combination as the effective date rectification control put forward the future control direction. Finally, it uses the case to evaluate the feasibility and rationality of the project cost and schedule control scheme.
