| 摘 要： | 针对传统灰色预测模型只能解决实数序列和区间灰数序列预测的不足,提出了三参数区间灰数的预测模型.通过定义三参数区间灰数的核和精确度,进而得到三参数区间灰数的核序列、"重心"点序列和精确度序列,从而将三参数区间灰数序列预测转变成实数序列预测,分别对三组序列建立预测模型,在不破坏灰数整体性的前提下,推导还原得到三参数区间灰数的预测模型,并对其进行精度检验,最后用一个实例来验证所建模型的有效性和实用性.

| Abstract: | Modeling objects of traditional prediction models are only suitable for real number sequences and interval grey number.Therefore,based on three-parameter interval grey number,and a new prediction model is proposed.The kernel sequences,the "center of gravity" sequences and degree of accuracy sequences are defined and predicted.Then the unbiased prediction model of three-parameter interval grey number is achieved by deducing and reverting.An example is presented to illustrate the usefulness and effectiveness of the proposed prediction method. |
