摘要
在城镇给水系统规划设计中 ,工业用水量预测占有重要地位。文章研究用经济学中的柯布 -道格拉斯生产函数建立城镇工业用水量预测模型 ,并以用水量预测公式拟合中的残差绝对值之和最小为目标函数 ,应用线性规划确定用水量预测公式中的参数 ,以提高拟合精度。实例分析说明了用该文所述方法预测城镇工业用水量 。
The forecasting for urban industrial water demand plays an importaut role in the planning and designing of the urban water supply system.In this paper, Cobb Douglass production function is used to build the forecasting model for urban industrial water demand. The minimizing sum of the absolute values of residuals, which are obtaind from regression analysis with the water demand formula, is taken as the objective function, and linear programming is applied to determine the formula parameters in order to enhance the regression precision. The case study shows that the formula has high precision.
