摘要
长期以来,宾馆行业多采用"节余比"指标来评价用水效率,容易产生"鞭打快牛"的弊病。采用数理统计方法,以分部位用水定额为基础,辅以调整系数方案,遵循模型构建的科学性、有效性、易操作性原则,建立了宾馆行业用水效率评价模型,并提出了节水指数的概念和计算方法。
The ＂ratio of water consumption＂ has been widely adopted in evaluating water use efficiency of hotels, but this method may lead to unfair punishment as a Chinese saying of ＂whip the fast and hard working＂. Therefore, a new model is established for evaluating water use efficiency of hotel sector under the principle of scientific, effective and operative, by means of mathematical statistics and water use quota of separate parts together with adjustment coefficient. The concept and calculation method of water conserving index are also presented.
