Abstract
The construction of water conservancy projects is increasingly restricted by non-technical factors such as climate, environment and society, so it is particularly important to optimize it to improve the benefits of construction enterprises. Taking a river dredging project in cold region as an example, this paper uses NSGA-II algorithm to carry out multi-objective optimization of the construction time-cost, and uses MATLAB software to compile the construction optimization program of dredging project. Finally, the optimal combination of construction time and cost is obtained. The results show that the optimization results are in line with the actual situation of the project and save about 10% of the investment for the project. The method in this paper can provide useful reference for the optimization control of the construction progress of the actual project.
