基于Alpha截集的模糊DEMATEL方法突发事件关键影响因素分析

Analysis on key influencing factors of emergencies by fuzzy DEMATEL method based on Alpha cut sets

为了改善已有突发事件关键影响因素分析中模糊DEMATEL方法在处理模糊信息过程中存在的不足,以原油油轮气体泄放为例,采用基于α截集的模糊DEMATEL方法分析关键影响因素和相互关联关系。研究结果表明:该方法能够得到不同视角的分析结果区别于传统方法得到的一组结果,从而很好地验证方法的可行性和有效性。研究结果可为模糊DEMATEL方法的改进和突发事件关键影响因素研究提供参考。

In order to improve the shortcomings in the process of handling fuzzy information by existing fuzzy DEMATEL method for the analysis on key influencing factors of emergencies,taking the gas discharging of crude oil tanker as an example,a fuzzy DEMATEL method based on Alpha cut sets was employed to analyze the key influencing factors and the interrelationship among factors.The results show that this method can obtain the analysis results from different perspectives,which are different from a set of results obtained by traditional methods,so as to verify the feasibility and effectiveness of this method.The research results can provide reference for the improvement of fuzzy DEMATEL method and the research on key influencing factors of emergencies.
