| 摘 要： | 本文通过引入灰色系统理论,对该理论的建模方法和精度检验方法进行了简单全面的介绍。并通过实例讲解了该方法的具体运用。该方法在对拟建工程进行投资估算时不仅有需要历史资料少,无需估计其它参数的特点,而且还有很高的预测精度。这恰恰符合了灰色系统的小样本高精度的特点。

| Abstract: | This article has carried on the simple comprehensive introduction to method of this theory's modelling and accuracy test through introducing into grey system,and explained this method concrete utilization through the example.The method not only needs less historical data,does not need to estimate the characteristic of the other characteristic parameter,but also has the very high forecast precision.This has conformed exactly to the characteristic of gray system's small sample high accuracy. |
