核事故发生时,采取正确的应急决策可以减轻事故的后果和危害.考虑到核应急决策的多目标性和模糊性,并针对传统AHP法的不足,利用三标度AHP法建立了多层次应急决策评估模型.模型较大程度的减小了评价的主观性,具有操作性强、稳定性好的特点.将模型与模糊层次模型计算结果进行比较,二者对方案的优劣排序是一致的.但模型在对最优方案的取舍上分辨率较高,对核应急决策具有实际的指导意义. In the event of a nuclear accident, the correct emergency decision-making can reduce the consequences and harms of the accident.According to the multi-objective and fuzziness of nuclear emergency decision-making and the deficiency of the traditional AHP method, a multi-level emergency Decision-making evaluation model.The model reduces the subjectivity of the evaluation to a large extent, has the characteristics of strong operability and good stability.Comparing the results of the model with those of the fuzzy hierarchy model, the two are in good agreement with each other However, the model has a higher resolution in the choice of the optimal solution and has practical guidance to nuclear emergency decision-making.
