【摘要】 城市月供水量规律分析和预测是供水企业调度管理工作的重要组成部分。以天津市为例,考虑到供水量的季节规律变化,提出了基于季节指数的水量预测模型,并进行了预测结果准确性的验证。结果表明,预测值和真实值相对误差的绝对值在0.559%~5.803%之间,能较好地满足月供水量预测要求。更多还原

【Abstract】 Variation analysis and prediction of urban water supply quantity monthly is an important part of dispatching and management for water supply enterprise.In view of the seasonal variation of urban water supply quantity in Tianjin,the water supply quantity prediction model based on seasonal index was set up and the prediction accuracy was tested.The results showed that the absolute value of relative error between predictive values and actual values was 0.559% to 5.803%,and could meet the requirement of monthly water prediction.更多还原
