摘　　要：在评选综合效益最优给水排水工程方案时,常用加权平均评分法,作者对采用该法时,如何更合理地确定评价指标的权重值进行了分析.指出了常用的几种确定权重值方法的不足,提出用非零值对比法来确定评价指标的权重值,同时对该方法的分析过程和计算方法作了介绍,并列举了用此法进行综合效益分析的实例.Weighted averaging estimation (WAE) method has been adopted widely to evaluate the comprehensive benefit for optimal programme of water and wastewater engineering. The author searched more rational methods to determine the weightiness and found some weakness in the traditional way. Finally a new deal called un-zero compared method to determine the weightiness for evaluated index in WAE is proposed. The analytical process and the calculation method of this method are prescribed with practical example of comprehensive benefit evaluation in this paper.
