基于改进的GM（1,N）货运量预测模型
A forecast model for freight volume based on improved GM(1,N) model
摘要
Abstract
In order to minis the excessive error from traditional GM(1,N) mode in freight volume forecasting, this paper uses the idea of equal-dimension gray filling to improve the traditional GM(1,N) mode. Meanwhile, using the new forecast data to replace the original data, this paper proposes an improved GM ( 1, N) model. Through a comparative analysis of the results of the two models can be seen that improved GM (1, N) model in forecasting accuracy has been significantly improved than traditional GM (1, N) model. This model can be more timely and accurate reflection of changes in the data. This model, with simple calculation and higher accuracy, has a high practical and research value in the field of freight volume forecasting.关键词
