摘　　要：针对实际工作中出现不等时距的情况,依据灰色模型的建模机理提出了一种不等时距序列的灰色预测模型背景值的新的计算方法,并建立了新的不等时距序列的灰色预测模型,通过算例表明其效果优于传统的做法,有较高的拟合和预测精度.For unequal interval appeared on practical work,a new calculation formula about background value based on modeling mechanism of gray model was established for forecasting unequal interval grey.Moreover,a new unequal interval grey forecast model was established.The example illustrated that the effect is better than the that of the traditional method and possesses high forecasting accuracy.

关 键 词：不等时距序列 灰色预测模型 背景值
