Network comprehensive optimization for schedule and cost in project construction based on PSO algorithm

Based on the principle of the maximum economic benefits can be obtained by optimizing the project network schedule, the comprehensive optimization of the cost, the supply of resources and the influence of latent uncertainties are considered systematically, and a mathematical model under multi-goal conditions is proposed in this paper. Then by integrating niche technology and using dynamic inertia weight, the particle swarm optimization algorithm is improved and is applied in the process of optimizing the model. Finally, an example is used to prove the improved PSO algorithm is of high effectiveness in solving the comprehensive optimization of project schedule.
