灰色模型结合Matlab数学软件预测工业需水量应用研究

Prediction of industrial water demand using grey model combined with a Matlab software

采用灰色系统理论法对宁夏灵武市工业需水量进行中长期序列预测,并结合Matlab数学软件对灰色模型进行求解。同时采用普遍使用的定额法对该区域的工业需水量进行预测,并对两种预测结果进行了对比分析。结果表明,预测结果相近,说明灰色系统理论法用于工业需水量序列预测有一定的优势。

The moderate-long term sequence prediction was conduced for the industrial water demand in Ningxia Lingwu City by grey system method. The grey model was solved combined with the Matlab software. Meanwhile,the norm method of general usage was adopted for the prediction of industrial water demand in this area. These two kinds of prediction results were compared and analyzed.The results indicated that the predictions were similar by the two methods and grey system method had certain advantage for the sequence prediction of industrial water demand.
