摘　　要：多目标水库洪水调度目标的权重确定一直是实际防洪调度中的难点,针对过去单一考虑主观权重或客观权重的多目标决策模式的缺陷,通过引入权重折衷系数的概念,提出了兼顾主观决策与客观决策统一的模糊循环迭代模型,可以同时得到方案优属度和目标权重。由于模型同时考虑了决策者意图和方案本身属性,使方案排序结果更为合理适用,将其应用于水库洪水调度方案的评价中,实例表明,该模型科学、实用。Due to the limitation that the objective weight or subjective weight is considered separately in the multi-objective decision-making, the concept of a tradeoff coefficient is imported, and a fuzzy iteration methodology paying attention to subjective and objective decision-making, which, at the same time, gives a objective weight and the relative membership degree of alternative, is presented in this paper. Since this model takes into account, in the meantime, the objective intent of decision-maker and the natural property of alternative, the ranking of alternative is more feasible and reasonable then former method. Finally, a case is applied in the appraisal of reservoir flood control to show that the model is scientific and practical.
