The Optimization Analysis of Cold Chain Logistics Distribution Route based on Particle Swarm Optimization (PSO) Algorithm

Abstract

Focusing that the goods delivered by cold chain has the characteristics of easy corrosion, distribution network and complicated distribution routes, we put forward particle swarm optimization (PSO) algorithm to make optimal distribution strategy and solve the VRP problem in the process of distribution. Aimed at optimizing the shortest distribution route we establish universal math model and build PSO solving model of cold chain logistics distribution to realize the distance distribution optimization problem. The results of experiments shows that the cold chain logistics distribution strategy of PSO can make the distance shortest and solve the nonlinear problem of cold chain logistics effectively.
