Risk evaluation model for radiation protective countermeasures based on fuzzy entropy weight
On the basis of establishing a risk assessment index system, a model for assessing the risk of radiation protective countermeasures is proposed by introducing a fuzzy mathematics method and entropy weight theory, and the risk order of the radiation protective countermeasures is ranked by their entropy weight coefficients, which solves the decision problem of uncertain and fuzzy indexes in the risk assessment index system and could provide the decision-making basis for commanders in the process of nuclear accident rescue. The illustrative case study shows that the model could use the inherent information of the indexes adequately, and makes risk assessment for radiation protective countermeasures more reasonable, practicable and scientific.
Optimization model of emergency scheme based on entropy weight decision-making
Aimed at the fuzziness of the emergency scheme optimization, a multiattribute decision-making model based on entropy weight is presented. By digging the inherent information of candidate schemes adequately and adopting the method of entropy weight combined with experts scoring, the model can obtain a synthetic weight considering subjective and objective factors, and then entropy weight coefficients of candidate schemes are calculated, by which the optimal emergency scheme can be selected out. Case study shows that the proposed model is reasonable, reliable, and makes for decision-making scientifically, which provides a new approach to resolve fuzzy multiattribute decision-making problem and can be applied to assist commanders in making decision.
