On the basis of establishing the supply chain optimization model and analyzing the basic particle swarm optimization algorithm, an improved particle swarm optimization algorithm is proposed to solve the supply chain optimization problem. In the process of optimization, the algorithm replaces some bad fitness particles with good fitness particles, which makes the algorithm have the ability to filter, speed up the search and ensure convergence to the global optimal solution. The experimental results and the basic PSO are validated and compared, which shows that the improved PSO has better performance and is simple, fast and accurate.
