摘要
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 based on Bayesian,entropy weight method and prospect theory is proposed.The Bayesian method is used to judge the nuclear 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 alternatives;With the evolution of nuclear accidents,considering the evolution degree of nuclear accidents and the expectations 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.
