基于直觉模糊距离法的堰塞湖减灾方案选优

摘要

针对堰塞湖减灾群决策信息的不确定性与模糊性,为解决不完全信息条件下属性指标及专家之间存在的相互关联群决策问题,综合运用直觉模糊集理论、海明距离原理和熵权理论,将直觉模糊距离群决策方法运用到堰塞湖减灾决策过程中.工程实例研究表明,运用直觉模糊距离法决策出的最优方案具有较高的区分度和敏感性,增强了决策的客观性、科学性,能为堰塞湖减灾决策提供更为可靠的依据,具有较强的实用价值.%According to the uncertainty and fuzzy of group decision information of barrier lake disaster relief, and in order to solve the correlation between the indicators and group decision experts under the condition of incomplete information, intuitionist fuzzy sets theory, Harming distance principle and entropy theory are comprehensively applied to solve the problems of barrier lake disaster relief decision in the decision-making process. Cases show that intuitionist fuzzy distance methods have a higher degree of differentiation and sensitivity and enhance the objectivity, science of the decision-making, the model can provide reliable bases for the barrier lake disaster relief decision-making and has a strong practical value.
