Abstract
针对核事故应急决策问题,提出一种基于贝叶斯和改进VIKOR相结合的方法.利用贝叶斯理论对核事故等级进行判定,实现阶段性执行结果和即时信息对核事故等级的动态分析.针对核事故应急决策的初始阶段,采用熵权法得到属性的客观权重,利用VIKOR方法得到备选方案的最优选择;随着核事故的演化,考虑核事故演变的程度与决策者预期,引入累计前景理论实现对核应急方案的调整.最后,通过算例分析,验证所提出方法的实践性与有效性.
Aiming at the problem of nuclear accident emergency decision-making,an improved VIKOR method bas-ed on Bayesian,entropy weight method and prospect theory is proposed.The Bayesian method is used to judge the nu-clear accident level,and the dynamic analysis of the nuclear accident level is realized through staged execution results and instant information.For the initial stage of nuclear accident emergency decision-making,entropy weight method is used to obtain the objective weight of attributes,and VIKOR method is used to obtain the optimal selection of alter-natives;With the evolution of nuclear accidents,considering the evolution degree of nuclear accidents and the expec-tations of decision-makers,the cumulative prospect theory is introduced to adjust the nuclear emergency plan.Finally,an example is given to verify the practicality and effectiveness of the proposed method.
