【摘要】 以白化方程组为基础,利用梯形公式白化灰导数,同时利用新信息原理,得到一种改进的多变量灰色预测模型.应用实例表明:改进模型具有较高的模拟和预测精度,适用于原始数据序列为非齐次指数函数情形的预测,并且拓宽了灰色模型的适用范围.更多还原

【Abstract】 In this paper,based on the white different equation set and trapezoid formula,grey derivative is whiten,and by using the new information principle,a new grey prediction model was proposed.The comparative analysis show that the improved model is better in accuracy,when data satisfies non-homogeneous gray exponentially.And so on,the application of grey prediction model can be extended.更多还原
