用Matlab实现GM(1,1)灰色模型的供电量预测

The Gray Forecast GM Model(1,1) Applies to Forecast in Electric System by Use Matlab Software

介绍灰色预测模型GM(1,1)在电力系统中的预测应用,同时在Matlab平台上实现了灰色模型GM(1,1)函数的编制。以某市1995～2004年供电量数据为例,并通过此函数对该供电量进行了预测,为灰色数列模型GM(1,1)的应用提供了一种简便的运算方法。

This article introduces the gray forecast GM model （1,1） applies to forecast in electric system,have realized gray GM （1,1） model function establishment at the same time on Matlab software,have taken 1995 ～ 2004 Some years amounts of power-supply data as example,have forecast and by the fact that this function has been in progress to city amounts of power-supply,have been gray progression model GM （1,1 s） application has provided one kind of arithmetic handy way.
