摘要
运用灰色系统理论中“等维灰数递补动态模型”对城市生活用水量进行了分析与预测。一是对用水人口进行预测,并运用回归理论对城市生活用水量与用水人口的关系建立模型,对城市生活用水量进行了预测;二是运用等维灰数递补动态模型直接对生活用水量进行预测。
The urban life-water quantity is analyzed and forecasted by using the same dimension gray recurrence dynamic model of gray system theory. Firstly, the water-use population is forecasted, the model of relation between the water-use population and the urban life-water quantity is established by using regression theory, the urban life-water quantity is forecasted by using this model. Secondly, the urban life-water is forecasted by using directly. The actual example indicate the two forecast methods are both available.
