Optimization of subway intelligent construction management system based on BIM+GA+SA
In order to realize the optimal management of the construction period,cost,quality and other objectives of the subway TBM construction project,based on the BIM Revit platform,genetic algorithm(GA)and simulated annealing algorithm(SA)were introduced into the simulation and optimization of construction plans,and a subway intelligent construction management system based on BIM+GA+SA was constructed.The results showed that the system's built-in genetic algorithm(GA)+simulated annealing algorithm(SA)could avoid being trapped in local optimal solutions,and had strong local search ability,convergence,and stability.The system had achieved good ap-plication results in a shield tunneling section of Guangzhou Metro Line 3.Thirteen construction plans were selected from 768 construction organization plans,and the duration,cost,and quality of these 13 construction plans were compared by the system,providing the best construction plan for the project department to ensure that the construc-tion of the subway TBM project achieves the best comprehensive benefits in terms of duration,cost,and quality.
