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.
Application of Fuzzy Optimized Entropy Weight Model on the Risk Management of New Drug Research & Development Innovation Techniques Projects
OBJECTIVE:To construct a fuzzy optimized model based on entropy weight and to discuss the application of the model on the risk management of new drug researchdevelopment project.METHODS:Risk management model of new drug researchdevelopment projects was established by combining fuzzy mathematics and entropy weight theory.RESULTS:The new drug researchdevelopment projects can be optimized and ranked based on the evaluation results on the model.CONCLUSION:The fuzzy optimized entropy weight model can be applied for the evaluation in the risk management of new drug researchdevelopment projects,which serves as scientific base for the administrative decision.
PRANA - Decision Support System for Assessment of Countermeasure Strategy in the Long-Term Period of Liquidation of the Consequences of a Nuclear Accident (Agrosphere)
The description of the computer system PRANA DSS (Decision Support System for the Protection and Rehabilitation of the Agrosphere after a Nuclear Accident) for analysis of protective measures in the long-term after a nuclear accident is presented. The development of PRANA DSS is based on the use of geo-informational technologies and elaboration of approaches and methods of estimation of the consequences of the Chernobyl accident. The features of the system, its components and examples of PRANA implementation are considered.
