3. Based on the risk analysis methods of water resources system and water demand and supply model, a risk analysis model of regional water supply and utility system with large reservoir groups is put forward.

establishes risk analysis model of preventing flood in urban areas, indefinite evaluating model; sets up the model of drainage charges and an evaluating index system for cities which economize on water.

And in line with the special floodwater utilization measures,a risk analysis model for floodwater utilization was established,which makes the floodwater utilization safe and effective.

From the points of mathematical proceeding of uncertainty factors, the risk analysis model based on probability theory (related to the field of random) is introduced, and new risk analysis models based on fuzzy subordinative degree (related to the field of fuzzy), grey number (related to the field of grey) and unascertained mathematics (related to the field of unascertainty) are put forward.

A fire risk analysis model for assessing options for flammable and combustible liquid products in storage and retail occupancies

To this end, I describe a probabilistic risk analysis model that can be used to assess the benefits of different fire safety measures, focusing on reinforcing the emergency water pumps.

We accordingly develop a risk analysis model and associated likelihood-based methodology when the response follows either a gamma or reciprocal gamma distribution.

Watershed risk analysis model for TVA's Holston River basin

World literature was reviewed in order to derive a risk analysis model that would be helpful in the management of PAM.

One of the key problems in water resources system research today is how to quantify uncertainty, which is inherent in every water resources system. Uncertainties are the origin of risk in hydrology and water resources. In this paper, the types of uncertainties in water resources system are comprehensively concluded, such as random, fuzzy, grey and unascertainty, and the concept of uncertain system of water resources is puts forward. From the points of mathematical proceeding of uncertainty factors, the risk...

The multi-objective risk decision model includes the investment risk evaluation model and the multi-objective decision model. The investment risk evaluation model mainly concerns the probability characteristic of the risk index. Regarding the net-present-value as the investment risk evaluation index, the maximum entropy risk analysis model is set up. The maximum entropy density function of the model is obtained and all kinds of risk characteristic values are calculated. The multi-objective...

The multi-objective risk decision model includes the investment risk evaluation model and the multi-objective decision model. The investment risk evaluation model mainly concerns the probability characteristic of the risk index. Regarding the net-present-value as the investment risk evaluation index, the maximum entropy risk analysis model is set up. The maximum entropy density function of the model is obtained and all kinds of risk characteristic values are calculated. The multi-objective decision model mainly deals with the risk decision under the situation of multi-scheme and multi-risk characteristic values. The multi-objective decision model is established to resolve the problem of limited schemes, and the approach is applied to ideal solution sorting method to solves the problem about multi-object risk decision of investment projects under the situation of multi-scheme and multi-characteristic values. The feasibility and validity of the model is improved by a case study.

Using the existing successful experience for reference,Baicheng City of Jilin Province has established the local floodwater utilization system based on the local conditions.This system makes full use of lots of swamp and wetland and great inflow to compensate the short of water resources due to less rainfall and short engineering measures.And in line with the special floodwater utilization measures,a risk analysis model for floodwater utilization was established,which makes the floodwater utilization safe...
