<p>你觉得灰色系统有用吗？既然缺少那么多的东西，怎么能保证一定的准确性呢？</p>

zhangyongyxbwcc 发表于 2009-5-9 18:22

说的好啊！！！

zhangyongyxbwcc 发表于 2009-5-9 18:31

好啊！！！

mcmzy 发表于 2009-7-26 19:37

嗯，有道理。

xiaoguo 发表于 2009-9-7 13:00

？？？？？？？？？？？？？？？

比如某年长江水质的预测，不用灰色系统着手分析.就很难入手啊.灰色系统还是有点用的吧？

zijian0717 发表于 2009-9-9 18:39

灰色系统当然有用啦  事实证明了的

skyyk 发表于 2009-9-9 21:36

LZ说的很对！
灰色系统有多种方法，通过对数据进行处理，将少数据、无规律，转换为有规律、可处理的

从而得到一定得预测结果！
