摘　　要：针对城市供水方案多属性,多指标的特点,采用变异系数赋权法结合灰色关联理论,通过计算评价方案与理想方案间的优属度,建立了城市供水方案优选模型。应用该模型对郑州市引黄供水方案进行优选,结果表明该模型计算简便,结果客观可靠,为城市供水方案优选提供了科学依据。Aiming at the feature that the urban water supply schemes with multi-attributes and multi-indexes, adopted the method compared the variation coefficient to making rights with the theroy of gray correlation, a scheme optimization model for city water supply was established by calculating the optimum degree between the evaluting scheme and the ideal one. This model was applicated to the optimization of the water supply schemes for intake Yellow River to Zhengzhou City. The results have shown that this model is simple calculation, objective results, and can supply the scientific basis for the ootimization of city supply schemes.
