摘要
针对期望值方法的缺陷，将分区多目标方法（ＰＭＲＭ）应用到防洪系统最优规模决策中，该方法既考虑了经济上的最优性，又充分考虑了洪灾的风险性，克服了期望值方法的缺陷。应用表明，该法适合于具有风险因素的防洪系统规模的决策问题。
he deficiency of the conventional expect value method is analysed,and the parti-tioned multiobjective risk method is used to determine the optimal flood control scale.The optimization of economy and risk of flood are considered fully in this model. The deficiencies of the conventional expect value mothod and general eco-nomic method are overcomed in this method.Practical application illustrates that this method is suitable for such problems as flood control scale and optimal flood control frequency.
