/methodology/approach: In this paper, a PSO-GRNN model is proposed to predict the railway freight volume. In this model, GRNN is applied to … carry out the nonlinear regression analysis and output the prediction value, PSO algorithm is applied to optimize the GRNN … model by searching the best smoothing parameter. In order to improve the performance of PSO algorithm, time linear …
