基于灰色系统理论对辽宁省万元GDP用水量分析预测

Analysis and Forecast of Water Consumption of Million Yuan GDP in Liaoning Province Based on Gray System Theory

提出万元GDP用水量的概念,阐述了灰色系统预测的原理和使用方法.根据对原有数据的生成处理,利用已知的数据进行校验,建立数据模型,求出参数.最后对未来5年辽宁省万元GDP用水量进行预测.将计算值与原始数据对比发现,用该模型对万元GDP用水量进行预测方便、准确、实用,为未来用水量提供可靠的参考依据.

The concept of water consumption of million yuan is put forward,and the principle and method of gray system prediction are expounded.Based on the generation and processing of the original data,the data is modeled by using the known data,and the parameters are obtained.The million yuan GDP water consumption of Liaoning Province in the next five years is forecasted.After comparing the calculated value with the original data,it is found that,using the model to predict the water consumption of million yuan is convenient,accurate and practical,which can provide a reliable reference for future water consumption.
