As the construction industry becomes more sustainable in the future, such as green, ecology, and safety, the
higher the requirements for the ultimate objectives of the project.The traditional management objectives of investment,
duration, and quality can no longer meet the requirements of comprehensive optimization management. Therefore,
from the perspective of the project owners, the work introduced the safety and environmental objectives based on
traditional management objectives. The thesis analyzes the relationship between the objectives, and builds the
equilibrium optimization model. Moreover, this thesis uses multi-objective particle swarm optimization (MOPSO) to
solve the problem, and obtains a series of Pareto optimal solutions. Then, according to the specific requirements of
project management and the use of the efficacy coefficient method, the best solution is selected from the Pareto
optimal solutions. Finally, a Sichuan wind power project is taken as an example. The work used the MOPSO to run
1,000 trails, and calculate the mean and standard deviation. It verified the rationality of model and the practicability of
MOPSO.
