Forecast Model of Coal Demand Based on Improved Tandem Gray BP Neural Network

Guohua Gou

Abstract—In this study, we build a new coal demand prediction model of tandem gray BP neural network. Firstly we use 2000-2015 years coal demand data to establish three gray prediction models: GM(1,1), WPGM(1,1) and pGM(1,1); Secondly, by comparison, we select the best prediction model pGM(1,1) and at the same time take coal demand factors as the BP neural network input, 200-2015year of coal demand date for training and testing. Lastly we proceed to predict coal demand in China in 2016 and 2020. Prediction result is: mean relative error of the improved tandem gray BP neural network prediction results is 1.92%, which is lower 0.158% than pGM(1, 1) model and 0.28% than BP neural network model respectively.

Index Terms—BP neural network, gray forecast, coal demand forecast, tandem gray BP neural network.
