中文摘要:为了解决灰色预测模型中的随机挠动序列问题,本文在灰色系统理论以及灰色预测建模技术的基础上,通过梳理历史文献的研究结果,提出了一个具有缓冲作用强度可调整的新型缓冲算子,即α-因子缓冲算子,该算子具有强度可调整、形式统一、预测结果优良等特性.具体来说就是通过调整强度系数可以改变其缓冲作用的强度大小、形式上兼顾了弱化缓冲算子和强化缓冲算子的统一性、在一定范围内的应用中预测结果优于其他的缓冲算子.实证的结果的确显示出了这些优良性质.

Constructing of α-Buffer Operator and Its Properties
Abstract:In order to solve the problem of impact torsion series in grey model, based on the theory of grey system and technology of grey prediction, this article put forward a new kind of buffer operator with an adjustment coefficient of buffer effect, which has several characteristics such as intensity controllable, unity formality and excellent prediction results. To be more specific, the adjustable intensity can be modified by changing the adjustment coefficient of buffer effect, both the weakening buffer operator and the strengthening buffer operator are taken into account formality, and the predicting outcomes are more outstanding than others in some range. And the empirical results do show these properties.
