Abstract��
The data on the coal production and consumption in Jilin Province for the last ten years were collect- ed��and the Grey System GM (1�� 1) model and unary linear regression model were applied to predict the coal consumption of Jilin Production in 2014 and 2015�� Through calculation��the predictive value on the coal con- sumption of Jilin Province was attained��namely consumption of 2014 is 114.84 ×10 6 t and of 2015 is 117��98 × 10 6 t��respectively�� Analysis of error data indicated that the predicted accuracy of Grey System GM (1�� 1) model on the coal consumption in Jilin Province improved 0��21% in comparison to unary linear regression model�� |
