城市防洪减灾决策方案优化研究

城市防洪减灾决策的成功与否直接影响着将来的洪水所造成的损失大小.如何应用自然、经济和社会信息,经超前分析以确保实施某一优化方案之后所造成的损失最小是防洪减灾决策的核心问题.本文深入地分析了城市防洪减灾决策方案优化的众多影响因素,在此基础上把模糊优选神经网络模型应用到城市防洪减灾方案优化中,并建立了城市防洪减灾方案优化模型,并通过实例验证了其有效性.

Study on Decision-Making and Alternative Optimum of Center Urban Flood Control and Disaster Reduction

Whether the decision of flood control and disaster reduction is successful will affect the damage of flood directly.How to apply the natural,economic and social information, through anticipatory analysis,to ensure the minimum damage after practicing certain optimum scheme is a core problem in the flood control and disaster reduction decision-making.In this paper,the factors affecting this decision-making are analyzed,the fuzzy optimum selection and neural network are applied in schemes optimization of urban flood-control and disaster reduction,and the model of optimum schemes is established,whose validity is tested through example.
