摘要
将灰色模型应用于对给水管网漏损的预测,并用方差—协方差优选组合模型将灰色模型和二次指数平滑模型进行组合。实例分析表明,组合模型的预测精度优于单个模型,可用于对实际管网漏损的预测。
A gray model was used in water distribution pipeline leakage prediction. The model was combined with a second multinomial exponential smoothing model by variance-covariance. Application examples show that the combined model is more accurate than single model, and that it can be used in water distribution pipeline leakage prediction in practice.
