To eliminate flood disaster, which happened more and more frequently in China, a fuzzy-inference based neural network model is developed. This model can solve the problems of systematic difficulty, inefficiency, shortcomings of unable to self-study and inadequate in traditional method. Firstly, the detailed steps of forming the new model were given. Secondly, a case study was used to demonstrate how...
The comprehensive benefit evaluation system of floodwater utilization is a multi-objective multi-stage system integrating economic, ecological and social benefits as well as including quantitative and qualitative indexes. This paper deals with the application of variable fuzzy recognition model to benefit evaluations of floodwater utilization in Baicheng region, Jilin province. The result shows that...
Based on the characteristics of many factors with uncertainties in flood control, multi-objective fuzzy optimal theory and method is introduced, and multi-objective fuzzy optimal selection model of flood control's projects of storage and detention basin is established, and the model is applied in actual flood control, the problem of multi - objective decision system affected by certain factors and...
In modern emergency management, the coordination among governments in the early-warning procedure is very important, because a disaster is always followed by various kinds of secondary disasters. Aiming at this importance, a collaborative early warning method of transportation during snow disaster is established based on fuzzy comprehensive evaluation (FCE). First, factors that affect the early-warning...
The universal indicator system of water resources risk assessment has been built based on natural disaster risk theory, and it were disposed with rough set theory, which realized the attribute reduction to those indicators. Thus we can get target indicators in accordance with reality in the evaluation area and the weight of the indicators has been identified by subjective (Analytic Hierarchical Process)...
