| 摘 要： | 根据灰色系统理论中新息优先利用原理,在对缓冲算子和已有强化缓冲算子研究的基础上,构造了一类新的强化缓冲算子,有效解决了冲击扰动数据序列在建模预测过程中常常出现的定量预测结果与定性分析结论不符的问题.实例分析结果表明,这类新的强化缓冲算子能显著提高GM(1,1)模型的预测精度.

| Abstract: | According to the theory of prior using of new information in grey system theories,based on the present theories of buffer operators and some already existed strengthening buffer operators,some new strengthening buffer operators are established.The problem that there are some contradictions between quantitative analysis and qualitative analysis in pretreatment for vibration data sequences is resolved effectively.An example shows that the new strengthening buffer operators can increase the forecast precision ... |
