摘要
针对城市管网漏损率数据的非线性和随机波动性特点,建立了以马尔可夫链修正灰色GM(1,1)的预测模型,以2005年—2012年全国管网漏损率为研究对象,比较分析了灰色和灰色马可夫链预测结果,指出经马尔可夫链修正后的模型预测精度更高。
In view of the city pipe network leakage rate data had the characteristics of nonlinear and stochastic volatility,based on the Grey Markov Chain model,from 2005 to 2012 the national pipeline leakage rate as the research object,comparative analysis of Gray and Gray Markov Chain to predict the results,revised obtained by Markov Chain model prediction accuracy is higher.
