Application of improved multi objective particle swarm optimization and harmony search in highway engineering

Abstract

Highway engineering construction is a complex multi-objective management project, and the traditional multi-objective task management approach has been difficult to cope with the uniqueness of highway engineering construction management. In order to improve the efficiency of multi-objective management in highway engineering, the study proposes to construct a multi-objective management model using particle swarm and harmony search algorithms for highway engineering management. First of all, the study first explores the management indexes in highway engineering, and constructs the functional relationship according to the selected indexes. Then the particle swarm algorithm is used to optimize the database of the harmonic search algorithm, and the harmony search algorithm can be based on the optimized database to find the optimal solution for objective management. The experimental results show that the improved particle swarm and harmony search algorithm has good distribution and convergence. After the optimization of the proposed model, the multi-objective highway project management scheme is 39% ahead of schedule, 17% savings in input funds, and 2.56% and 3.56% improvement in highway quality indexes and ecological environment management indexes, respectively, compared with the original scheme. Therefore, the model has a good application prospect to formulate the optimal multi-objective management scheme with excellent performance to improve the management efficiency of highway engineering.
