| Abstract: | This article predicts demand for urban logistics on genetic algorithm and BP neural network algorithms,proving that the genetic BP neural network algorithms is better than a single algorithm in the forecast accuracy and convergence rate.Based on the extensive logistics industry,it proposes to adopt three logistics demand as the network's output indicators,improves the breadth and reliability of prediction,and puts forward a method of continuous forecasting in order to be used in actual decision-making. |
