摘　　要：针对水库生态调度的模型构建和求解问题展开研究,提出了一种耦合多目标相关分析、多目标优化和多属性决策的水库生态调度方法。基于对水库实际调度目标的抽取和数学描述,采用相关性分析方法,分析各目标之间的相关关系,从而构建出水库生态调度多目标模型。采用NSGA-II法对模型进行求解,获得Pareto最优调度方案。基于备选方案逐次淘汰法(SEABODE)对优化求解结果进行多属性决策优选,获得最终调度方案。将建模方法、优化算法、优选方法耦合,从而形成一种贯通“建模-求解-优选”全过程的水库生态调度方法。以林家村水库为例,验证了该方法的有效性和应用效果,从而为水库生态调度提供了一种新的思路和方法。In order to study the reservoir ecological operation model construction and solution,the method coupled with multi-objective correlation analysis,multi-objective optimization and multi-attribute decision making is proposed.Based on the extraction and mathematical description of the actual reservoir operation targets,the correlation analysis method is used to analyze the relationships among the targets,and thus a multi-objective reservoir ecological operation model is constructed.The optimal Pareto schemes is obtained using the NSGA-II to solve the model.The final scheduling schemes is obtained using an approach to successive elimination of alternative schemes based on the order and degree of efficiency(SEABODE).The whole reservoir ecological operation process of“modeling-solving-optimizing”is formed by the coupling modeling method,optimization algorithm and optimization method.Taking Linjiacun Reservoir as an example,the validity and application effect of this method are verified,providing the new idea and method for reservoir ecological operation.
