几种主要能源年产量的灰色预测
THE GREY FORECAST OF OUTPUT YIELD OF SOME CHIEF ENERGY RESOURCES
【摘要】 本文根据灰色系统理论[1]建立了我国几种主要能源指标年产量的残差GM(1,1)校正灰色模型的长期动态预测模型,经检验模型精度为一级,并提供了到2000年的预测值.
【Abstract】 According to the theory of the grey sytem we have developed,for the annual yield of some chief energy resources target, a dynamic statemodel GM (1, 1 ) for the grey forecast of error -rectify. Through testing, theprecision of the model is good. we have obtained the forecast date up to theyear 2000.
