权重的确定是多指标综合评价中的一个重要步骤。本文针对传统层次分析法(AHP)在实践中无法摆脱评估过程中的随机性及专家的主观随意性等原因使得确定的权重与实际相悖的不足，提出将群决策的思想融入AHP法。通过将专家意见做为对各个指标赋权的主要依据，并根据指标之间的相关逻辑来逐步调整各指标的权重占比，保持动态赋权，从而改进传统AHP法。然后根据建立的指标层次结构模型运用改进的AHP法求得主观权重，将其应用于供水绩效评估指标权重确定方法中，获得满意的效果。改进AHP法可以用于制定合理、公正的绩效评估体系，也可以应用于其他的评价指标体系权重确定。

The determination of weights is an important step in the comprehensive evaluation of multiple indicators. In this paper, the traditional AHP (AHP) can't get rid of the randomness in the evaluation process and the subjective randomness of the experts in practice, which makes the weight of the determination and the actual deficiencies, and proposes the idea of group decision making into the AHP method. By using expert opinions as the main basis for empowering various indicators, and gradually adjusting the weight ratio of each indicator according to the relevant logic between indicators, and maintaining dynamic empowerment, the traditional AHP method is improved. Then, based on the established indicator hierarchy model, the improved AHP method is used to obtain the subjective weight, which is applied to the method of determining the weight of the water supply performance evaluation indicator, and the satisfactory effect is obtained. The improved AHP method can be used to develop a reasonable and fair performance evaluation system, and can also be applied to the determination of other evaluation indicator system weights.
