摘要
本文通过对煤炭市场价格及其影响因素的分析,应用灰色系统理论建立了煤炭市场价格灰色动态预测数学模型.通过计算举例及误差分析表明,该模型的建立是合理的.它为煤炭市场价格的预测提供了一种有效的方法和手段.
the summary of this text draws an analysis to the market price of coal and influence factor, used grey systematic theories and set up the grey trends of market price of coal and predicts the mathematical model. And error analysis indicate through calculating for example, the setting-up of this model is rational. It offers a kind of effective method and means for prediction of the market price of coal.
