摘　　要：分析了防洪调度决策的多目标性、模糊性,并针对传统的相对优属度规格化公式存在的不足,采用基于影响度因子的改进优属度计算公式,同时以改进熵权法与二元对比定权法将目标的客观属性与决策者的主观偏好相结合确定综合权重,建立了多级模糊优选防洪调度决策模型,应用于大伙房水库防洪调度决策中,取得满意结果。Based on analyzing the fuzziness and multi-objectiveness in flood control decision making, this paper pointed out the shortages in fuzzy relative membership normalization function. And then, we improved this function based on objective affection degree. Furthermore, we mixed subjectivity and objectiveness in weight definition by mixing entropy and binary compare methods. Finally, a fuzzy optimization model was established for real-time flood control deeision making. The model was applied to the flood control decision making of Dahuofang Reservoir, obtained satisfying results.
