摘要
在灰色GM(1,1)模型和优化的等维递补GM(1,1)模型的基础上,构建了灰色+BP神经网络组合模型。对2001~2005年我国人口的变化分析后,建立人口总量模型进行预测,利用原始数据建立的灰色+BP神经网络组合模型预测我国2008年以后五年的人口总量为13.39亿、13.49亿、13.60亿、13.7亿、13.79亿,有逐年上升的趋势。经综合误差分析和后验差检验均为"优秀",说明该模型具有一定的应用价值。
In this paper, we built the grey combine with BP neural network model based on GM ( 1,1 ) model and the Improved GM ( 1,1 ) model. We analyze the changes of China's population of the year 2001 - 2005, then we establish the model to predict the total population. Using raw data to predict the next five years China's total population, they are 1339000000, 1349000000, 1360000000, 1370000000, 1379000000 ,obviously there is a yearly upward trend. After the integrated error analysis and late error examination the model shows “excellent”, and has a good value.
