摘要
根据“灰色控制系统”理论,建立了贵州省煤炭产量的GM(1,1)预测模型,并给出算法及框图。通过关联度分析及残差辩识,对贵州省“七·五”计划期及“2000年”规划期的煤炭产量做出长期预测。
According to the Grey Control System Theory, the writer sets up a revisionary GM(1.1) prognosis model, and also gives the algorithm and frame figure, Through relative degree analysis and error identification, a believable forecast is made for the coal product in the Seventh Five-Year-Plan period and by the year 2,000 in Guizhou.
