基于熵权的用水总量与效率管理绩效考核研究

Research on Water Consumption and Efficiency of Management Performance Evaluation Based on the Entropy Method

提出用于考核用水总量与用水效率管理绩效的评价指标体系和方法。采取熵权法分析考核指标的权重系数,避免了权重系数确定过程中的主观性;引入三角形隶属函数,将考核指标划分为成本型、效益型指标,从而使用水总量与用水效率管理绩效考核过程更加科学合理。采用以上方法,对济南市2011年度各县、市、区的用水总量与用水效率管理进行绩效考核。考核结果显示:此方法能够适用于用水总量与用水效率管理的绩效考核,并能较好的考核各县、市、区的水管理能力和水平。

In this paper, a method and an index system of management performance evaluation about water consumption and water et- ficiency are proposed and the entropy method is used to analyse weight coefficient of the evaluation index in order to avoid the subjec- tivity in the process of determining weight coefficients. The triangle subordinate function method is introduced and the evaluation in- dicators are divided into cost index and benefit index to assess the management performance evaluation on water consumption and wa- ter efficiency, thus making the evaluation process more scientific and more reasonable. By adopting the method, this paper has evalu- ated water consumption and water efficiency of management performance in all counties of Ji＇nan in 2011. The results show that this method can be applied to water consumption and water efficiency of management performance evaluation and can assess the ability and the level of water management in all counties of Ji＇nan Province better.
